About
I’m a full-stack software engineer with 4+ years of experience building production web applications, responsive customer-facing interfaces, and reliable backend services. I work across the stack using React.js, TypeScript, Next.js, Node.js, Python, and SQL, and I enjoy turning product requirements into clean, accessible, data-driven experiences.
Along the way, I’ve integrated REST APIs, implemented secure authentication with JWT and OAuth 2.0, optimized PostgreSQL/MySQL/MongoDB queries, and improved performance with caching strategies. I also bring hands-on experience with Docker, AWS/Azure, CI/CD, and automated testing (Jest/Cypress), plus additional exposure to AI-powered search, RAG pipelines, and LLM integrations.
