Crafting experiences,
not just code.

A brief introduction to who I am and what I care about building.

I'm a Frontend-focused Full Stack Developer with 2+ years of professional experience turning complex product requirements into clean, performant web applications. My foundation is React.js — I live in component architecture, hooks, state management, and the performance micro-details that separate good apps from great ones.

Beyond the frontend, I'm comfortable building APIs with Node.js and Express, designing MongoDB schemas, and deploying production-ready workloads on AWS and Vercel. More recently I've been deep in the GenAI space — building RAG pipelines, AI agents, and LLM-powered features using OpenAI, LangChain, and vector databases like Qdrant.

I've contributed to large-scale learning platforms at PW Skills, building and optimizing frontend systems used by thousands of users. Working on high-traffic applications has strengthened my focus on performance, scalability, and clean architecture — principles that directly reflect in my code.
