What I'm looking for
AI Full Stack Engineer with 6+ years building scalable web applications, SaaS platforms, and AI powered products from idea to production.
I currently lead development at 10Pearls as Senior Lead Software Engineer, driving technical decisions and architecture across frontend, backend, mobile, and database layers. I lead design and implementation of AI powered features using LLMs and RAG systems, and provide technical leadership and code review guidance across the team. Before this, I spent over two years there as a Senior Software Engineer building and maintaining full stack applications with React, Next.js, React Native, and Node.js.
Earlier, I worked at Tone and Tighten in the United States for two years, building backend services and REST APIs and working across the full development lifecycle from feature development to production support.
My core stack: React and Next.js on the frontend, Python with FastAPI and Django, and Node.js with Express on the backend. On the AI side, I work with LLMs, OpenAI APIs, Claude, LangChain, RAG pipelines, vector databases, AI agents, and embeddings, focused on integrating AI where it creates real measurable value rather than adding it for its own sake.
I like owning a project end to end, from architecture and database design through AI integration, frontend, testing, and production support. Open to senior engineering roles or technical leadership where AI is a core part of the product.
