How I Work

From problem to production.

I take ownership of features from concept to production. You describe the problem, I design the solution, build it, deploy it, and make sure it stays running.

Architecture First

I map out data flows, failure modes, and scaling concerns before writing code

Ship Fast

Working software in days/weeks, not months

Production-Ready

Monitoring, error handling, documentation, and operational runbooks included

No Handoffs

I handle frontend, backend, infrastructure, and deployment

Built for startups and small teams where velocity and ownership matter more than specialization.
