About Me

Software engineer with 5+ years of experience building scalable systems (ERPs, Fintech, SaaS, B2B), AI Agents and data pipelines. I enjoy turning messy, real-world workflows into reliable, production-grade products, ranging from straightforward internal tools to complex systems with automation, analytics, and strong operational reliability.

Recently, I've been working on AI Agent systems, automation and instant quoting price prediction with ML, 3D geometry visualization, workflow orchestration with LangGraph, observability, and shipping both backend services and React/TypeScript product experiences. I care a lot about clean architecture, measurable performance, and systems that are easy to operate in production.

I got into technology in college through web development and never stopped what still hooks me is breaking down complex problems and shipping solutions that make people's work faster and decisions smarter.
