Ideas are a start.
This is the work.

From the data underneath
to the page people finally see.
A few things I’ve helped bring to life.

How I work.
From idea to impact.

Choose a discipline. Follow the thinking.

FULL-STACK PRODUCT

From schema to checkout to the page students open at 2 a.m. before an exam — I build and run the entire thing.

Scale is a number.
Efficiency is the craft.

30→1

LLM calls per conversation.
47% more data captured.

At VARA5 I built a real-time voice personalization engine on OpenAI Realtime that turns natural conversation into confidence-scored guest profiles — then re-architected extraction into a single end-of-call pass.

7.4M+

Weekly API requests

Served from self-hosted Docker on DigitalOcean across Supabase Postgres, Auth and Realtime.

85%

Database load removed

Schema and query work that cleared a 1,200+ req/min bottleneck during exam season.

28/28

Production scenarios, byte-identical

Led the migration of a 20,000-line legacy commission platform to React with a zero-drift live cutover.

THE COMMON THREAD

Build something useful.
Make it hold under load.
Give it room to grow.
