Is your AI-powered MVP built on a fragile 'vibe-coded' foundation? Are you struggling to scale a prototype that was built with lightning speed but is now plagued by bugs, security holes, and technical debt? I transform brittle AI prototypes into robust, **production-ready applications**. As a senior AI engineer specializing in the **Node.js** and **React** ecosystem, I bridge the gap between rapid, AI-assisted development and the disciplined engineering required for scalable, secure software. But robust software is only half the battle. The other half is making it *work for your business*. I design and implement **intelligent automation workflows** that connect your apps, eliminate manual tasks, and free up your team to focus on high-impact work. Whether you need to rescue a failing project, automate a core business process, or build a scalable MVP from the ground up, I provide the expert oversight to ensure your AI initiatives deliver real, measurable value. **My Core Services:** * **🤖 AI Code Rescue & Remediation:** I conduct deep **AI code audits** to debug, refactor, and secure fragile codebases (especially those built with LangChain.js). I turn unmaintainable prototypes into stable, scalable assets ready for real users. * **⚙️ Intelligent Workflow Automation & Integration:** I design and build digital assembly lines for your business. I offer a full spectrum of automation solutions: * **Rapid Integration:** Using **Zapier, Make.com & n8n** to connect your existing tools and solve immediate process bottlenecks. * **Custom API Development:** Building custom **Node.js** APIs and webhooks to connect proprietary systems or handle complex logic that no-code tools can't. * **AI-Powered Decisions:** Infusing your workflows with intelligence using the **OpenAI API** to triage support tickets, qualify sales leads, or generate content automatically. * **🚀 Custom AI Solution Development:** I architect and build bespoke AI solutions from scratch, from **Custom GPTs** and intelligent **AI Agents** to complex RAG (Retrieval-Augmented Generation) pipelines that leverage your private data. * **👨‍🏫 AI Engineer & Career Mentorship:** I provide 1-on-1 coaching to help developers navigate the AI landscape, master tools like LangChain.js, and build a successful career in AI engineering and automation. **My Tech Stack:** * **Languages:** Node.js, TypeScript, JavaScript * **Frameworks:** React, Next.js, Express.js, NestJS * **AI / LLM:** LangChain.js, OpenAI API, LlamaIndex, Vector Databases (Pinecone, Qdrant) * **Automation Platforms:** Zapier, Make.com, n8n Ready to move past the prototype phase and build a real business? **Send me a message with your project details or book a session to get started.** --- ### Service Packages * **Package 1: AI Code Audit & Production-Ready Roadmap** * **Description:** Have an AI-generated MVP that feels unstable? I'll perform a comprehensive review of your codebase. You'll receive a detailed report identifying security vulnerabilities, performance bottlenecks, and a concrete, actionable roadmap to make your application **production-ready**. This is the perfect first step to de-risk your project. * **Package 2: Intelligent Automation Workflow** * **Description:** Let's put a core business process on autopilot. We'll map out a high-impact workflow and I'll build a robust automation to solve it. Ideal for **automating lead qualification**, **triaging customer support tickets**, or **streamlining content pipelines** using the best tool for the job—Zapier, Make, or custom Node.js scripts. * **Package 3: Scalable AI MVP Development** * **Description:** Need to build an MVP the *right* way? I'll architect and develop a **scalable MVP** from day one, using professional, spec-driven development practices. We'll build a strong foundation with clean, documented code and a modern stack (Node.js, React) to avoid the technical debt that plagues "vibe-coded" projects.

Freelance Api testing Developer - Guillaume Faas

Building software has always been a passion of mine. This is still true after almost 15 years of experience in various environments and business sectors. I've never really considered it work but "problems to solve". Yes, I love puzzles or anything that requires you to turn your head around. Passion also means curiosity and hunger for knowledge. I regularly read blogs, articles, and books and practice katas by myself. Some of my favourite authors are Robert C. Martin (aka Uncle Bob) and Mark Seemann. Continuous improvement is a mindset I consider essential. If I had to pick one priority when building a product, I would choose quality. This has always been what I put first. I'm not satisfied when "It Works", it must also be done well. I always tried to improve the team I joined wherever I've been. Whether by providing experience, a fresh eye, ideas, or mentoring younger peers. About mentoring, sharing knowledge represents a key aspect of my participation in a team. I do believe that knowledge is useless if you keep it to yourself. We need to use our knowledge to teach and inspire others, the same way others have inspired us. Putting this all together, it’s quite clear I advocate Software Craftsmanship. Hearing about this ideology for the first time has been one of the biggest milestones in my career. It is the perfect match for what I consider important in terms of mindset. Since then, I’ve continuously tried to spread the ideology by sharing ideas and methodologies. Feel free to take a look at my GitHub account: https://github.com/Tr00d You'll find katas I do for fun or coaching purposes, but you'll mostly see how I code.
