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.

After completion of my post graduation in Master of computer application, I have been working as a web developer and in last 5 years I have worked on number of projects in various range of complexity. Started with core PHP/MySQL and then dived into CMS to learn various popular CMS like Wordpress, Drupal, Modx, etc. out of which I have obtained expertise in Drupal development. In Drupal, I have customized available modules and integrated designs from HTML layouts. Moreover, I have also worked on frameworks of PHP like Smarty and also working on Facebook App and web pages. Being a quick learner and tech enthusiast, I keep update of all the new technologies in web development field.
I have experience as both a front-end developer and a full-stack developer. I've also worked as a technical team lead, and a software engineering manager. My areas that I currently focus on teaching for are React, DevOps, Cypress, and Spring Boot. Have also done a few thousand hours of tutoring over the past 11 years, mostly for software development. I'm conscious of keeping people from feeling overwhelmed or lost. I meet you where you are in your current skill level. When we work together, the learning is enjoyable and empowering.
IMPORTANT: If you want to contact me, and your timezone is significantly different, feel free to just open a session request during my timezone evenings (after 8pm till midnight). I've noticed that figuring out the request details via chat is extremely cumbersome. I'm a professional developer working on Application Performance Management in Dynatrace; currently stationed in Gdynia, Poland. I've done a number of jobs in the past, including Graphics Driver development at Intel, Game Development at Huuuge Games and other, potentially unrelated things. I've started programming wanting to be a game developer, so there's a huge chance I can help you with your C++ game project. I also know my ways around the low-level parts of C and C++. Right now my main focus at work is Node.js, so if you have some questions about that, ask away. I also did a fair share of weird front-end experiments, so Three.js, WebGL and stuff like WebWorkers don't scare me. And finally, if you need some tips about Haskell or functional programming in general, that's my personal hobby area. In general, don't hesitate to ask, as I always try to get the feeling for your problem so that we both end up satisfied!
