AI-Powered Full-Stack Developer / Support Engineer for [login to view URL] We are looking for developers to help us grow [login to view URL], a platform where we build, publish, sell, and deploy software products. This is not just a one-off coding task. We are looking for people who can potentially work with us long-term across development, maintenance, deployment, and customer support. What you’ll be doing Your responsibilities may include: * Developing new applications and features * Improving and extending our existing applications * Fixing bugs and technical issues * Reviewing and improving existing codebases * Deploying applications and configuring production environments * Helping customers install, deploy, configure, and customize purchased software * Responding to technical customer questions * Creating new products from specifications * Testing applications before release * Improving performance, security, UX, and code quality * Maintaining existing products as dependencies and frameworks evolve * Working with GitHub repositories, branches, pull requests, and issues AI agent experience is required A major part of our development process is AI-agent-assisted software engineering. You should already know how to work effectively with tools such as: * OpenAI Codex * Claude Code * similar autonomous/agentic coding tools We are not looking for someone who simply copies code from ChatGPT. You need to understand how to use coding agents professionally: give them good specifications, inspect an unfamiliar repository, plan changes, delegate implementation, review generated code, run tests, debug failures, iterate, and verify that the final result actually works. AI should make you dramatically faster — it should not replace your engineering judgment. Technical skills Our projects may use different technologies, so you don’t need to know everything. Experience with some of the following is valuable: * PHP / Laravel * JavaScript / TypeScript * Vue / React * [login to view URL] * Tailwind CSS * Node.js * MySQL / PostgreSQL * Redis * Docker * Linux * Git / GitHub * REST APIs * Stripe * Cloud deployments * CI/CD * [login to view URL] / WebGL * Swift / SwiftUI for some projects Strong general software-engineering skills are more important than knowing every framework on this list. What matters to us We want someone who: * can work independently * can understand an existing codebase quickly * knows when AI-generated code is wrong * doesn’t consider “the agent said it’s done” to mean the task is actually done * tests their work * communicates clearly * can investigate problems instead of waiting for step-by-step instructions * cares about shipping working software * is comfortable working across multiple small and medium-sized products Customer support Some work involves helping AIFabrico customers. A customer may say: “I purchased this application but I can’t deploy it.” We expect you to be able to inspect the problem, communicate with the customer, configure or modify the application where necessary, and help get it running. So written English and the ability to explain technical issues clearly are important. Long-term opportunity We’re interested in finding multiple reliable engineers whom we can repeatedly assign work to as AIFabrico grows. There will potentially be work involving: support → bug fixes → customization → product development → new applications Good developers can therefore receive ongoing work rather than a single project. When applying Please include: 1. Your GitHub profile or examples of software you’ve built. 2. Your main technology stack. 3. Your experience with Claude Code, OpenAI Codex, or other coding agents. 4. An example of a real project where you used an AI coding agent productively. 5. How you verify AI-generated code before shipping it. 6. Your hourly rate. 7. Your weekly availability. 8. Your timezone. 9. Whether you’re comfortable communicating directly with customers. Please do not send a generic AI-generated proposal. Start your application with: [login to view URL] so we know you’ve actually read the brief.

Hi — Elias here from Miami. I see you're looking for a full-stack developer for your AI project at AIFabrico. The goal seems to be integrating advanced AI capabilities into your platform to enhance functionality and user experience. The real challenge often lies in ensuring scalability and maintainability. What usually matters most here is how the AI integrates with existing systems, as well as managing user roles and permissions effectively. The tricky part is usually balancing performance with the complexity of AI logic, especially as you expand. My approach would focus on building a modular architecture, allowing for easy updates and feature additions. I'd aim to create clear separation between the AI components and the core application, ensuring reliability and future-proofing the system. I've worked on similar platforms that required robust AI integrations, focusing on performance optimization and seamless user experiences. A few questions to better understand the scope: Q1 – What specific AI functionalities are you looking to implement initially? Q2 – How do you envision user roles and permissions interacting with the AI features? Q3 – Are there existing systems or APIs you plan to integrate with? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Hello, I’ve read the brief carefully and understand that you’re looking for more than a developer who can simply generate code. You need an independent full-stack engineer who can inspect unfamiliar codebases, use AI coding agents effectively, verify the output, troubleshoot production issues, and communicate directly with customers when required. My workflow is: Understand → Plan → Delegate to AI → Review → Test → Debug → Verify → Deploy When working with tools such as Claude Code, OpenAI Codex or similar coding agents, I first understand the repository and requirements, provide focused specifications, review every meaningful change, run the appropriate tests, inspect edge cases and only then consider the implementation production-ready. I can work across the full lifecycle: New feature development Existing application improvements Bug investigation and fixes Codebase reviews/refactoring Database issues For customer issues, I’m comfortable investigating the actual problem, explaining the solution clearly, and helping the customer get their purchased application running rather than simply forwarding technical instructions. g fixes → customization → product development → new applications—fits well with how I prefer to work. I’d be happy to start with a repository review or a small technical task so you can evaluate my development and AI-assisted engineering workflow directly. Best regards, RAHEEL

The real requirement here is disciplined AI-assisted development, not simply knowing Laravel or React. I’d use coding agents to inspect unfamiliar repositories, break work into verifiable changes, and accelerate implementation, while keeping architecture decisions, code review, testing, and production debugging under direct engineering control. For AIFabrico, I’d also treat deployment and customer support as part of the engineering workflow: reproduce the issue, trace the actual cause, fix it cleanly, and verify the installation rather than handing back generated code. Which part of the stack is currently most active in AIFabrico: Laravel/PHP products, React/Vue applications, or a mix?

Hey, the emphasis on using AI coding agents with real engineering judgment is what caught my attention, especially reviewing generated changes instead of trusting an agent blindly. I’d use Codex or Claude Code to inspect unfamiliar repos, plan focused changes, then run tests and review the output before anything ships. The tricky part is switching between development, deployment, and customer issues without losing that verification step. What kind of AIFabrico projects would you want the first assignment to focus on?

You want people who can ship new products, keep the live ones healthy, and help buyers get them running. I already ship live software: paid OCR tools, storefronts, and production apps that stay up. AI agents do the heavy lifting, so I can start right now and send a live working sample of one of your products in 24-48 hours. You will see the quality, a buyer-ready install path, and how I would help a customer stuck on setup, before we lock in ongoing work. Which product should I use for that first live sample?
