About

I build production software that real users depend on. From marketing automation platforms processing thousands of emails to financial systems handling secure transactions, I focus on writing code that scales and doesn't break at 3 AM.

Currently a Founding Engineer at Cresca, where I architected the entire backend infrastructure, distributed job processing with BullMQ, real-time analytics dashboards, and production deployments on AWS with proper email deliverability setup.

My stack: React, Next.js, TypeScript on the frontend. Node.js, PostgreSQL, MongoDB, Redis on the backend. I also work with AI integrations (Gemini, OpenAI) and handle DevOps, Docker, PM2, CI/CD pipelines.

I care about system design, writing maintainable code, and building things that actually solve problems. Won a hackathon once. Still figuring out why Docker containers refuse to start sometimes.

Projects

Things I've built

A mix of side projects and real work. Most of these started as "I wonder if I can..." and turned into something useful.

SkillForged

AI tool that generates personalized learning roadmaps. You tell it what you want to learn, how much time you have, and it creates a week-by-week plan with resources.

My Finhub

Financial transaction platform. Had to figure out how to make payments secure and fast at the same time — ended up with JWT auth, Redux for state management, and clever caching.
