Highlighted Projects

A selection of products I've architected, built, and deployed end to end.

KeyHold Pro — Multi-Tenant Inspection SaaS

Replaced a Texas inspection firm's third-party reporting product with a platform I designed and built. PostgreSQL row-level-security tenancy, billing, admin console and an office review workflow, covered by 336 automated tests. In daily production use.

Multi-Store Commerce Platform

Lead engineer and operator for live stores in Bangladesh and the UK: checkout, stock, courier sync, COD reconciliation, my own Android SMS gateway, phone-OTP login and in-house web push. Diagnosed an 18.5 s admin query down to a single index.

Ad Measurement & Attribution
