№ 00 · Positioning
Strategy, engineering, and delivery — under one roof.
I grew up on the JVM. My first commits went into Grameenphone's ERP; my last decade has been split between senior engineering, university lecturing, corporate training at Ernst & Young, and long-form public-sector consulting on the Digital Sylhet City Project.
Today, as Product Development Manager at KriyaKarak, I run the whole arc — discovery, architecture, delivery, iteration — with a preference for small teams, sharp scopes, and measurable outcomes.
