Codex operator -- > Chat/gpt work ai operator -- > Website posting/web admin using Codex to develop/manage and populate the website, fix bugs and do template all in Codex - daily site admin

Project Overview I am seeking an experienced full-stack developer or small team to audit, improve, secure, and modernize an existing production website and infrastructure. This is **not a greenfield project**. An existing frontend, backend/API, PostgreSQL database, content, media, forms, administrative functionality, Docker deployment, and VPS environment are already in place. The current website has experienced intermittent outages and loading failures. Based on prior troubleshooting, the likely problem area is a combination of deployment/runtime stability and security rather than a simple frontend bug. Known symptoms/issues include: Website sometimes hangs or times out while Docker containers still appear to be running. Nginx and Docker are functional, but the deployment is not yet ...

I have a PHP / Laravel web application that must stay perfectly in step with our on-premise Microsoft Active Directory. The only focus is data synchronization—specifically, keeping user profile details (display name, email, phone, title, etc.) in real time. No authentication or group management work is required; sign-in is already handled elsewhere. Here is how I picture the job: • Establish a secure LDAP/LDAPS connection to our on-prem AD from the Laravel app (the server is behind a VPN; I can expose the required ports). • Map the AD user attributes I will provide to the corresponding columns in my users table, then create or update those records automatically. • Implement an event-driven or near real-time strategy—DirSync/Change Notifications, queued j...

My current Laravel application is stable, but it has reached the point where genuine AI-powered features and better runtime performance are essential. I want three things achieved in one focused sprint: 1. New functionality with the OpenAI API • Content generation endpoints that accept a prompt and return well-formatted copy in JSON. • A language-translation service that can be called from anywhere in the codebase (middleware-friendly), returning translated strings while respecting existing localisation files. 2. Faster, leaner execution through the Gemini API Gemini will handle selected heavy computations now performed server-side. I need thoughtful caching, graceful fall-backs, and measurable response-time improvements without breaking existing routes or queu...

I need a cloud-based platform that handles every aspect of job scheduling and dispatch for plumbing companies. The application must run smoothly in modern desktop browsers first; mobile or tablet support can come later, so please optimise the user experience, layout, and performance with that priority in mind. At its heart the system should take incoming work orders, match them to available technicians, and generate the most efficient daily plan automatically. To make that happen I want three AI-driven capabilities baked in from day one: • Automated job allocation • Predictive maintenance alerts • Route optimisation The system will need a clean admin dashboard where staff can create, view, and edit jobs, plus a dispatcher view that shows live technician status on a ...

I’m ready to turn a concept inspired by Airtasker and Uber into a production-ready marketplace where users can book home, transport, and delivery services from their phone or browser. The project covers three experience layers—Customer, Service Provider, and Admin—and must run smoothly on iOS, Android, and the web with a single, shared back end. You will own the full product cycle: UX/UI design, scalable back-end architecture, real-time matching and tracking, in-app chat, ratings, secure payments, and an analytics-friendly admin console. Stripe (or a comparable gateway) and location services need to be wired in from day one, and the codebase should be clean enough for future micro-service expansion. Deliverables • Interactive wireframes and final UI assets for all ...

MVP Build — Quote Request We're looking for a freelance developer or small team to quote an initial MVP build. This is a rough-scope request to get a ballpark quote — not a full technical spec. Additional phases/tiers will be scoped separately once we're underway. What we're building (high level) A web platform that connects to third-party business software a client already uses (accounting/ERP-type systems, CRM/marketing platforms, etc.), pulls their data into a secure cloud environment, and gives the client a simple portal to log in and view/query that data — including an AI-assisted question-answering feature over their own data. Core skills required Backend development (Node.js/Express or equivalent) — building and hardening API routes, workin...

PROJECT OVERVIEW I am building Pipe-r, an AI-powered field-service management platform designed specifically for plumbing companies. The goal is to create a polished, scalable SaaS product that can compete with platforms such as Jobber and ServiceTitan while providing deeper plumbing-specific workflows, better automation, a faster user experience, and practical AI tools. A prototype/application shell currently exists at and was created using Base44. It establishes the product direction, interface, navigation, and portions of the intended workflow. The selected developer or agency must first audit the existing application and determine what can safely be retained, improved, migrated, or rebuilt. This is not a simple website or basic scheduling application. I need a production-ready, mu...

My priority is to build and refine Microsoft Dynamics 365 Business Central through new AL objects, with the spotlight on custom tables and pages. These pages must support clean data entry, run their own validation, trigger custom workflows, and surface key metrics in dashboard-style reports.

Additional work will include, when required, adjusting RDLC or Word layouts for reports, extending posting and approval workflows, exposing data through APIs or web services, and tuning SQL for performance. Deliverables • AL code for tables, pages, and supporting codeunit...

I need a seasoned PHP developer to design and build a clean, well-documented API from the ground up. The project centres entirely on backend logic—there is no front-end work—so your focus will be creating efficient endpoints, solid authentication, and clear JSON output. Here’s what I have in mind: • Code in modern PHP (8.x preferred) and follow PSR standards. • Use a framework or micro-framework you’re comfortable with—Laravel, Lumen, Slim, or even plain Composer packages are fine—as long as it stays lean and easy to maintain. • Include token-based authentication, structured error handling, and basic rate limiting. • Provide concise documentation (endpoints, parameters, responses) plus a Postman or Insomnia collection so I can...

I need a solid PostgreSQL-backed RESTful API to drive the Solar TwinPro web application. Your task is to design the database schema and expose clean, versioned endpoints that cover full CRUD functionality for each core resource in the system. The web front-end will consume JSON, so consistent status codes and clear error handling are important. Please structure the project so it can be deployed easily (Docker preferred, but I am open to other simple approaches) and include concise documentation; an OpenAPI/Swagger spec is ideal so the front-end team can plug in without guesswork.

I represent a marine-sector company that now needs a full digital presence—far more than a brochure site. The goal is to deliver a polished corporate website supported by an online booking engine, a content-management system our staff can run without developers, and a secure client portal that streamlines every post-booking interaction.

I need a purpose-built B2B e-commerce portal that allows corporate clients and our field sales representatives to interact inside a single, secure environment. Unlike a standard storefront, the site should emphasise relationship management: every user signs up, lands on the appropriate dashboard, and can start a private conversation thread with the rep assigned to them before any order is placed. Core workflow I have in mind: • User registration & profile creation for two roles—client and sales rep. • Internal messaging so both sides can discuss pricing, availability and order details in real time. (We already manage product data in-house, so a full catalogue can be added later; the immediate focus is on the people connection.) The underlying platform simply needs...

I need a seasoned .NET backend developer to build a suite of RESTful APIs that will power our next release. The core of the job is pure API development—no UI work—so you should feel completely at home writing clean, well-structured C# code in .NET (preferably .NET 6 or later), wiring it up with Entity Framework or Dapper for data access, and documenting everything with Swagger / OpenAPI. Here’s what the APIs must handle: • User authentication (token-based, ideally JWT) • Full CRUD operations for our primary data models • Smooth third-party integrations, starting with two vendors that expose JSON endpoints I’ll provide the database schema, access credentials, and a concise list of integration endpoints on kickoff. You’ll return: 1. So...

My production C# application currently targets .NET Framework 4.8 and has started to show its age. I need it migrated to a supported, more secure runtime (ideally the latest LTS release of .NET), with every dependency updated and any obsolete APIs refactored. The primary driver is security: I want all outstanding vulnerabilities removed, HTTPS enforcement tightened, and modern authentication/cryptography practices adopted throughout the codebase. During the upgrade I also want to introduce a clean integration layer so the app can talk to external systems (REST and, if feasible, simple message-queue endpoints). This should be implemented in a way that keeps the core logic decoupled and unit-testable. Finally, a handful of persistent UI glitches—visual misalignments and sporadic cont...

I’m ready to move my Paying-Guest/hostel operations off spreadsheets and into a single, web-based platform built with .NET (C#), SQL Server or MySQL, HTML, CSS and JavaScript. The application will sit on a hybrid setup—part cloud, part on-prem—so clean separation of concerns and a painless deploy script are important. Core scope • Secure, role-based authentication for Owners, Students and Administrators, each landing on a tailored dashboard. • Property and room management with live availability, quick search and filters. • Student self-registration followed by a guided room-booking flow that updates availability in real time. • Integrated rent ledger: capture payments, show history, flag overdue amounts and let me export or print offline recei...
