Philosophy
Thoughtfully designed.
Carefully engineered.
Enhanced with intelligent automation.
Built to stand the test of time.

I work with founders, technical leads, and teams who need someone that can own the full stack — from database schema to deployed product. Not a handoff. Not a consultant. Someone who builds alongside you until it ships.

Selected Work

Three products. One standard.

"Real-time clarity. Zero spreadsheet hell."

Full-stack analytics platform built from scratch for growth teams operating at scale. Architected the event pipeline, designed the data model, and engineered a live dashboard that processes millions of events per day — sub-2s query response at p99.
