I like owning the whole problem. For six years I've shipped web, mobile and AI products for fintech, logistics and events teams, and I stay on after launch. I founded Precision InfoTech, where 9 in 10 clients come back for the next build. I write code the next engineer can read, and I care about fast, accessible interfaces.

Typed end to end

Zod at every boundary and typed query hooks in the client. Contracts fail at build time, not in production.

Built to run

Containers, CI/CD, structured logs, rate limits and API docs are part of the first release, not a later clean-up.

Secure by default

I'm Microsoft-certified in identity and access. RBAC, MFA and least privilege go in from the first commit.

Technical assessments with on-device proctoring
Candidate code runs entirely in the browser with Monaco and Sandpack, so there is no server-side sandbox to run. Identity checks use MediaPipe face detection, and no video leaves the device.
