I build production-ready web apps, MVPs, SaaS platforms, and agentic AI systems that are clean, scalable, and built to solve real business problems.
My strength is connecting two worlds: solid full-stack engineering and practical AI integration.
That means I don’t just build features. I design systems that are reliable, easy to maintain, and useful enough to drive real product growth.
I’m one of the engineers behind TubeOnAI, an AI-powered summarization and productivity platform used by 100k+ users.
Working on a real AI product at this scale taught me that great engineering is not only about writing clean code. It is about understanding the business, the users, the cost, the architecture, and the long-term maintainability of the system.
I care deeply about building products that are:
- Business-aligned — solving the right problem before writing the first line of code
- Scalable by design — fast to ship, but strong enough to grow
- Reliable in production — predictable, secure, and cost-conscious
- Clean for developers — readable architecture, maintainable code, and strong DX
- Simple for users — intuitive experiences that hide technical complexity
If you need a technical partner who can take ownership from idea to production, I can help you build something solid.
I design and build AI-powered systems using agentic workflows, RAG pipelines, embeddings, tool-calling, deep search, and Model Context Protocol integrations.
I build scalable backend systems and modern frontend interfaces using technologies like Node.js, Go, Next.js, React, Prisma, PostgreSQL, MongoDB, Redis, and Docker.
I work on performance, reliability, data persistence, real-time communication, browser extensions, desktop apps, and clean system architecture.
