AI products.Built. Scaled.

I build production AI products and the infrastructure that makes them reliable — from multimodal apps and recommendation agents to evaluation gates for high-stakes LLM systems.

01 / Selected work

AI systems with public proof.

Evaluation infrastructure, multimodal products, retrieval agents, and production systems with real users and adoption.

02 / Philosophy

I care about the version of AI that survives outside the demo — where real users, real money, and real failure modes are on the line.

As a technical founder I've shipped a Mongolian-first multimodal nutrition app to 2,500+ users, co-founded PrimitiveBench — a vendor-neutral evaluation layer for AI infrastructure now partnered with CalCompute — and built recommendation and retrieval systems serving students across 16+ universities.

The throughline is discipline around the model: structured outputs, golden datasets, agent traces, deterministic fallbacks, and CI eval gates. Flexible reasoning becomes a reliable product only when its output is measurable, debuggable, and safe downstream.

I move at founder speed but build with engineering restraint — because taste, distribution, and reliability are all part of systems design.

03 / Capabilities

Technical depth, made legible.

Core patterns behind measurable, debuggable agentic systems.

01

Production AI products

From prototype to paying users, uptime, subscriptions, and growth.

02

Evaluation infrastructure

Golden datasets, agent traces, structured validators, and deployment gates.

03

Multimodal intelligence

Fine-tuned vision-language models with reliable structured outputs.

04

Agentic recommendations

Tool calling, retrieval, ranking, and live external data integrations.

04 / Experience

Founder speed, engineering discipline.

Production ownership inside small teams and real constraints.
