My Approach

Why Work With Me

Business-First

Hybrid pipelines — AI where needed, deterministic code where it's cheaper — drastically reducing your API costs.

End-to-End Delivery

Backend, async workers, cloud infra, and the frontend. No hand-off friction — one engineer who owns the stack.

Production-Grade Code

CollateralQC processes 100s of documents monthly with zero downtime. Real systems, real teams, not toy demos.

Clear Communication

Regular updates, clean documentation, honest timelines. You'll always know where the project stands.
