Java Jobs

Estoy en la etapa final de reclutamiento de un desarrollador full-stack Java con React y requiero una mirada experta que valide con rigor el nivel senior de los candidatos. La evaluación debe profundizar en tres frentes: conocimientos sólidos de Java, destreza con React y probada experiencia en el ciclo completo de un producto full-stack. El plan es aplicar una prueba basada en el desarrollo de una aplicación completa. Espero que definas el enunciado, aclares los requisitos funcionales y no funcionales, acompañes al candidato durante la resolución (solo para atender dudas de alcance) y, finalmente, revises el resultado con criterios de calidad de código, arquitectura, cobertura de pruebas y buenas prácticas de documentación.

Tengo una aplicación desarrollada en Java con Spring Framework que corre sobre PostgreSQL y se edita en Eclipse IDE. Se actualizo una tabla en la base de datos por lo que implica actualizar los codigos correspondientes para que esos nuevos campos sean también afectados. Alcance inmediato: • Se necesita generar un formulario que contenga los combos anidados de Estado, Municipio y Localidad. • Ya hay un modulo similar que lo hace, de ahi se puede tomar el ejemplo. Para lograrlo necesito que: • Revise s el código fuente, detectes los cuellos de botella y apliques las correcciones pertinentes. • Implemente s mejoras de manera limpia, siguiendo buenas prácticas de Spring y Java. • Entregue s cada ajuste probado con PostgreSQL y un bre...

Necesito una versión inicial sencilla de una aplicación Android que use la cámara frontal del teléfono colocado en el parabrisas para detectar en tiempo real las patentes de los vehículos que pasan. Cada matrícula reconocida debe consultarse al instante contra mi base de datos propia (puedo facilitar un endpoint REST o un archivo local). Cuando la patente coincida con un registro, la app debe generar una notificación inmediata—visual y/o sonora—para alertar al conductor. No requiero una interfaz compleja: basta una pantalla con la vista previa de la cámara, la última patente leída y un indicador del estado de conexión con la base. Tecnología: soy flexible; puedes emplear ML Kit, OpenALPR u...

I want to recreate an app similar to that of what I have as an compiled APK format. Your first step will be to analyze the package (JADX, apktool, baksmali—whatever you prefer) and set up a clean Android Studio project. From there I want three kinds of changes: a refreshed design/layout, a couple of new features that I’ll outline once you’re inside the code, and a sweep to fix the bugs that have been frustrating current users. Deliverables • Fully readable project source code along with APK • Updated UI/UX applied across all screens • New features integrated and working as specified • Identified bugs resolved and regression-tested • Re-built, signed APK ready to install, plus the complete modified source project The rebuilt app mus...

I’m gearing up to build a production-ready set of smart contracts and need an experienced developer to bring the on-chain logic to life. The core of the assignment revolves around architecting, coding, and testing the contracts themselves; tokenomics, dApp front-end, and broader infrastructure are handled elsewhere. To streamline selection, I’d like to see concrete past work—live contracts, GitHub repos, audits, or anything that proves you’ve shipped secure Solidity code before. Please highlight any experience with Truffle, Hardhat, Foundry, or comparable frameworks, plus the security tools you rely on (Slither, MythX, Echidna, etc.). Gas optimization and adherence to current best practices (e.g., EIP-2535, OpenZeppelin upgradeable patterns) will weigh heavily in m...

**Android App for Learning Stock Market Trading Charts** We are building an Android-based educational tool designed to teach users how to read and analyze stock market trading charts. The app’s primary focus is on providing beginners with a hands-on, interactive experience to learn core concepts like candlesticks, volume, and price action. It’s not an e-commerce or social networking platform—every element of the app should serve the educational purpose. **Key Features & Requirements:** 1. **Interactive Stock Chart:** * An embedded interactive stock chart will be central to the app. Users should be able to: * **Pinch-to-zoom** for adjusting time scales. * **Scroll** through historical data and price action. * **Tap** on chart elements for instant...

I need an interactive Android prototype that clearly demonstrates three core flows: user authentication, in-app messaging, and push notifications. The goal right now is proof-of-concept, so polished visuals are less important than showing the screens, transitions, and basic logic that tie these features together. What I will give you • A short written user journey for each flow • Basic wireframes and a color palette • Sample push-notification copy What I expect back • A tappable Android prototype (Figma, Adobe XD, or similar—let me know your preference) that lets me move through sign-up/login, open a chat, send/receive a message, and trigger a push notification demo • All source files, neatly organized layers, and exportable assets • A quic...

I need a complete, production-ready cryptocurrency built on a private blockchain that reaches consensus through Practical Byzantine Fault Tolerance (PBFT). The scope starts with selecting or building the core ledger, moves through token definition, and ends with a running network that my team can operate behind our firewall. Because PBFT prioritises speed and deterministic finality, I expect node software that demonstrates low-latency block confirmation in a controlled environment. Docker-based deployment or a similarly portable setup is preferred so we can spin up multiple validator nodes quickly during testing. Deliverables • Source code for the ledger and consensus layer • Token specification (supply, decimals, fees) implemented in the chain logic • CLI or lightwe...

I’m ready to roll out a dedicated Android e-commerce app and need the full build—interface, logic, and secure email-based sign-up all wrapped into a polished APK. The core flow is straightforward: browse products, add to cart, check out, and let users manage their orders from a personal dashboard. Only email/password authentication is required, so include account creation, sign-in, password reset, and session handling with best-practice security measures (JWT/Firebase Auth or an equivalent). Because the project is Android-only, lean on native components in Kotlin or Java and follow current Material guidelines so the UI feels modern and smooth. To keep things tidy, I’ll review progress in a Git repo. Please structure the code cleanly (MVVM or similar), comment critic...

I have a personal domain and need to edit straightforward portfolio site written in Java Next. For this first phase I only require a basic, professional-looking draft that I can publish quickly and refine later. What I expect right now: • A slim Java Next project scaffold with one home page and one dedicated “Projects” section, styled in a clean, corporate manner. • Deployment instructions so I can push the site to my own hosting under my domain. • A short tech note outlining how I could later bolt on extra modules such as an interactive gallery, a contact form, or even a small blog section without rewriting the core. Keep the code organized, commented, and standards-compliant (HTML5, CSS, minimal JavaScript where needed). If you can deliver the runnable p...

We have a ride-hailing app built with React + Capacitor (Android). Currently, the driver’s GPS stops sending updates when the app is minimized or the screen is locked. As a result, the driver disappears from the passenger map until the app is reopened. We need someone to implement background GPS tracking so that: Location keeps updating even when the app is minimized or the screen is off. Foreground service runs with a persistent notification (“Sharing location”). The app is excluded from Android battery optimization if possible. Works smoothly on Android 10+ (tested on latest versions). The solution must send location updates to our API/WebSocket every few seconds. Tech Stack: Frontend: React + Capacitor Backend: Node.js (Express) Hosting: VPS (Ubuntu) Goal: M...

I’ve just begun experimenting with the Claude Code and Warp AI IDEs and I’d like one-on-one guidance that takes me from first-time setup all the way to writing, testing and debugging production-ready Python code. Here’s what I want to cover, in roughly the order I expect to need it: • Smooth installation and configuration of both IDEs on macOS, including any extensions or CLI tools they rely on. • Day-to-day workflow basics—opening projects, using the command palette, chatting with the embedded AI, and version-control integration. • Moving beyond “hello world”: advanced coding techniques, refactoring with AI assistance, prompt engineering inside the editor, and pair-programming style usage. • Effective debugging: stepping t...

I already automate parts of WhatsApp Web with Python + Selenium, but I now need it wrapped into a clean Windows-only desktop application. Your task is to take my existing logic, extend a few predefined features I will share (think scheduled message blasts, dynamic contact selection, and media attachments), and present every parameter in an intuitive GUI. The stack must stay in Python and Selenium; for the interface you may choose Tkinter, PyQt, or Kivy—whichever lets you deliver a responsive, installer-ready EXE with no command-line setup for the user. Core expectations • Integrate my current scripts and add the extra functions I outline. • Build a stable GUI that lets users log in to WhatsApp Web, adjust each feature, and monitor progress in real time. • Packa...

I’m putting together a simple yet complete Android learning project built in Android Studio Ladybug with Java 17. The goal is to mimic a real-world authentication flow from scratch. Here’s what I need: • A launch screen containing two EditTexts (email and password) plus a login button. • Credentials are stored and validated locally—use SharedPreferences or Room, whichever you feel is cleaner for a beginner-friendly codebase. • After successful validation, the user is taken to a second screen that pulls the saved name, email, and profile picture and lays them out in a tidy profile view. Nice-to-have touches If time allows, feel free to add a “Remember Me” checkbox, proper password masking, and an option to upload or change the profile ...

I have a published Android photo-editing app that needs a quick round of bug fixing. You can preview it here: What I’m seeing: • Saving & Exporting – edited photos are saved but there need to check the last screen. I need the original resolution preserved when users tap Save/Share. • User Interface – a few interaction quirks still slip through. Please run through the main editing screens, identify anything that blocks a smooth flow, and patch the root cause. Scope is intentionally lean: diagnose, fix, and supply an updated APK plus the modified source files with a brief change log. If you can replicate the low-quality export and resolve it fast, that’s the priority; polishing the UI comes right after. The project is small but important, so clea...

I converted my React JS website into an Android APK, but Google sign-in breaks once it’s inside the app. On the web, the flow built with react-google-login works perfectly; however, the APK relies on a custom-wired version of the same logic and the OAuth pop-up never completes, leaving users stuck at the login screen. I need you to trace the exact point of failure—whether that’s an OAuth redirect, SHA-1 mismatch, missing intent filter, or a WebView setting—and implement a rock-solid fix so users can authenticate with their Google accounts from the APK just as smoothly as they do in the browser. Core expectations • Diagnose and correct the Google login flow inside the existing Android build. • Keep the current React codebase intact where possible, but ref...

I’m looking for a freelancer with expertise in Machine Learning, Deep Learning, and Software Defined Networking (SDN) to develop a complete project titled: “Intelligent Detection Mechanism for DDoS Attack Prevention in SDN-VANET.” The goal is to design and implement an intelligent, ML/DL-based detection and mitigation system that can detect Distributed Denial of Service (DDoS) attacks in SDN-enabled Vehicular Ad-hoc Networks (VANETs). 1.

I’m expanding my existing Jenkins setup and want a clean, repeatable process for two things: • Bring up a brand-new Windows agent, register it with my current Jenkins controller, and label it appropriately. The box will need a current Java Development Kit installed so that it can run build, scan, and test steps without complaining. • Tweak the current declarative pipeline so that when the scan/test stage fails it marks the build as “unstable” (or whatever status you recommend) and then carries on to the remaining stages instead of aborting the entire job. I’ll give you SSH/RDP or JNLP credentials to the Windows machine along with access to the Jenkins UI. Please deliver an updated Jenkinsfile (with clear comments), the exact node configuration settings...

The project involves 3 app being created but interlinked App 1 - Displays ads on a android Tablet, it just rotates the ads on 15 second cycle. the ads will be pictures or silent videos.

I have a set of unicode protected PDF files that hold complete voter records—names, addresses, voter IDs and their images—laid out as printable voter slips. I need a small, reliable piece of software that can extract each PDF, parse every field (image included), and place the results into a single Excel workbook using a custom layout that I will share once the project starts. Key points you should know before you quote: • The PDFs are all in the same unicode format; • Every record must transfer in full, including the embedded photo, so the tool has to pull and save images directly into the sheet (not just as file paths). • The Excel output isn’t a simple column-by-column dump; I need a tailored structure that mirrors the order I already use internally...

I need an experienced Android developer who can jump in right away to turn my utility-app concept into a production-ready APK and set up the accompanying admin panel. The core app is strictly a utility tool—no e-commerce or social-networking elements—so the focus stays on clean functionality.
