About

I’m a Full-Stack Developer focused on AI & GenAI, with a keen eye for detail and a strong focus on delivering results quickly. Over the past 4+ years, I’ve helped startups transform ideas into scalable solutions — from crafting intuitive UIs with React, Next.js, and Flutter, to building robust backends using Node.js, Express and Firebase. Lately I’ve been building AI agents, RAG pipelines (Gemini embeddings, vector search on Astra DB, LangChain) and MCP integrations, alongside MVPs and SaaS applications. On the analytics side, I’ve implemented Mixpanel and PostHog tracking, routed event data through RudderStack, worked with Google Ads and Meta Ads data, built pipelines that bring App Store and Google Play data into Mixpanel, and prototyped AI agents for customer sentiment analysis. With hands-on experience in AWS, MongoDB, and Supabase, I thrive in environments that demand both technical precision and collaboration. Let’s connect and build something that matters!
