About Me
I'm a full-stack engineer with 9+ years of experience building complete products from the ground up — crafting clean, responsive UIs in React and Next.js while designing the distributed backend systems that power them with Node.js and NestJS. I've worked across the entire stack: relational and NoSQL databases, Redis caching, event-driven queues, AWS infrastructure, and more recently AI integrations using LLMs and RAG pipelines. I care about clean architecture, readable code, and developer experience as much as I care about what ships to users.
