Christian Vega · Data & AI Technical Lead

I lead data & AI delivery.
And I ship the proof.

I'm a data & AI technical lead. I set direction and drive delivery, and I stay hands-on enough to architect the systems and earn engineers' trust. Six years in regulated healthcare data, now leading AI & automation at Optum (UnitedHealth Group).

0 live production systems
0 listings served (Nidopr)
0 contracts ingested (LicitaPR)
0 healthcare & enterprise data

The proof, in numbers

What these systems do.

~64,000 property listings aggregated & served (10+ sources, nightly) Nidopr
+44% → +5% valuation-model bias after back-testing & trust-gating Nidopr ML
40 automated production health checks → phone / Discord / email Nidopr Monitor
~1.24M government contracts ingested (~90% of universe) LicitaPR
422K → ~345K vendors resolved to entities (Splink + deterministic) LicitaPR
Live on AWS business OS: builder + POS + KDS + inventory FT-OS

How I lead

I set the direction.
And I stay close enough to the build to make it real.

Six years across healthcare and enterprise data, with a clear leadership climb and three production systems taken from concept to live. I direct the architecture, the model evaluation, and the AI-assisted delivery layer, and I own the judgment and verification that decide whether it holds up. Give me a team and I multiply what they can ship.

Off the clock

Can you see a breakup coming in the aggregate?

A question I couldn’t shake, chased down with 16 years of real US search data and hand-rolled statistics — then I spent most of the effort trying to prove my own answer wrong. It even cites the peer-reviewed paper that argues against its own thesis.

Move the month, watch the gauge settle, run the forecast out, then read the caveats sitting right next to the charts.

Have data? Let’s make it think.
