Hi, I am
Hands-on CTO | Lead Engineer
I lead engineering at Hexis, the nutrition platform used by 40% of the Tour de France peloton and 50% of the Premier League.
Remote · Dubai · US and EU hours
Hexis
Multi-day queries now return in under 700ms. That turnaround was a key factor in closing a $2.1M seed round.
Every athlete has years of history, with millions of rows per table, and multi-day queries took minutes. I replaced a heavily joined schema with co-located JSON storage and rewrote the query patterns.
AI startup (client)
Scored 100% on the Vectara RAG benchmark across 3,000 queries.
I built it from scratch. It reads whole data rooms and answers analysts' questions with page-level citations. Before any answer is written, a verification step drops every page that doesn't support the question, so it says "not found" instead of guessing.

Athletes in Europe, the US and Australia get a nearby API and database.
Each region writes to its own Postgres node, pglogical keeps them in sync, and HAProxy fails over to the others. Schema changes go through an automated freeze, drain and re-enable step.
Verizon Media / RYOT
Synchronous responses under 300ms, and onboarding cut from weeks to days.
I designed the backend from scratch, including a headless Blender pipeline that turns huge creator files into versions that render on iOS and Android browsers, with no human in the loop.
