Spring Boot Jobs

Necesito levantar desde cero una plataforma SaaS B2B que automatice auditorías digitales complejas. La idea es que el sistema recopile datos a través de integraciones directas con herramientas de marketing digital, plataformas de análisis de datos y nuestros CRM, procese esos insumos con modelos de inteligencia artificial y expida, sin intervención humana, informes, hojas de cálculo y recomendaciones accionables. Planeo un desarrollo por fases que cubra backend, frontend, base de datos y todas las integraciones externas. Mi stack preferido para la lógica de servidor es Java, por lo que agradeceré experiencia sólida en ese ecosistema (por ejemplo Spring Boot, Quarkus o similares) y familiaridad con arquitecturas escalables orientadas ...

I’ve been assigned a tricky maintenance ticket in our Spring MVC / Spring Boot code-base and, as someone still ramping up on Java, I’m stuck tracking down logical errors that sit squarely in the service layer—the part where our business logic lives. The symptoms: data flows in correctly from the controllers and persists fine through the repositories, yet the results returned to the UI are wrong. Unit tests covering the affected services either fail or pass with unexpected values, so I need a fresh pair of expert eyes to walk through the code with me, isolate the faulty branches, and refactor or rewrite the logic so every scenario behaves as intended. What I’ll provide • I can share my screen and follow the steps suggested by you. I can’t provide yo...

It includes: A 277-item service catalog with search and live bill calculation Razorpay payment integration (full payment or advance, test mode currently) An owner dashboard to manage bookings WhatsApp booking confirmation . With an AI integration

Beyond application development, I’ve had the opportunity to design, develop, and take responsibility for web platforms supporting international congresses and technical events. These experiences involved delivering production-ready solutions under real deadlines and collaborating with different stakeholders and technical teams. I’m particularly interested in opportunities involving: Full-Stack Web Application Development .NET / ASP.NET Core Development Spring Boot amp; Java Development API Development amp; System Integration React / Vue / Angular Applications SaaS Platforms amp; Business Applications Remote Engineering Teams Freelance and Long-Term Projects I’m looking to collaborate with international teams, startups, and companies where I can contribute tech...

This assignment centres on building and refining data-driven services in both Java and Python for the analysis layer of our internal platform at Niti Technologies India Software, Kharadi – Pune. The code you ship will ingest raw records, transform them through clean, well-tested business logic, then surface the results through REST endpoints that other teams consume. I already work with both stacks daily, so you will find an established Git workflow, CI pipeline, and SonarQube gating in place. Expect to pair with our QA group for manual and automated test coverage and to attend brief, on-site stand-ups; Pune-based contributors slip naturally into that rhythm, yet our processes are structured enough for fresh graduates to grow quickly. Deliverables • Modular Java 17 / Spr...

BajriX is an active construction-materials marketplace running on React, React Native, Spring Boot, PostgreSQL and AWS. I need an experienced developer who can drop straight into the existing repository, understand the current architecture and take the lead on building out new features while keeping the codebase clean, modular and well-documented. Your day-to-day work will involve: Experience with e-commerce or marketplace logic, AWS authentication flows and third-party API integrations will make you especially effective here. When you reply, please link to past work that shows similar responsibilities—code samples, GitHub repos or live projects are all welcome. Also include your typical availability and expected charges so we can map out milestones right away. I’m ready...

I have a full-stack Java codebase that I need set up, walked through, and examined from top to bottom. My first priority is uncovering any security vulnerabilities or hidden backdoors, so you will need to comb through the entire stack—server-side, client-side, build scripts, and deployment configs—looking for risky patterns, outdated dependencies, or suspicious commits. Once the security sweep is complete, I also want your eye on execution speed. Any hotspots that slow response times, blocking calls, or inefficient algorithms should be flagged with clear, actionable fixes. You are welcome to profile locally or spin up a test environment; I’ll provide repo access and a clean VM image so you can reproduce the build. Deliverables • Written audit report that lists ev...

I need production-ready software that proves out the latest frontier-model capabilities from end to end. The work spans everything from designing the data layer to wiring up sleek UIs, then packaging and deploying so that real users can click around and see the model in action. You can reach for the stack that lets you move fastest—Python/Django or FastAPI, Java/Spring Boot, TypeScript/Node.js or , even Rust, C#, or modern C++. Cloud services (AWS, Azure, GCP) and containerisation with Docker/Kubernetes are welcome if they speed delivery; I’m flexible as long as the final result is easy to stand up and maintain. Frontier-model features sit at the heart of each build. Whether it’s natural-language understanding, computer-vision pipelines, data-driven recommendations, or ...

<PLEASE APPLY EXPRIENCED ONLY, its more than 2 year contract >The task spans both green-field builds and upgrades to our existing Java Spring Boot back-end and React typescript front-end codebases. New modules will be spun up from scratch while legacy screens, APIs, and database mappings receive incremental improvements, so versatility across the full stack is essential. We are looking for long time contract, flexible time, remote work, PART TIME for an IT company. SHOULD HAVE GOOD KNOWDGE USING Ai during work. please send Biodata with details
