Fractional CTO for startups and scale-ups in the US & EU, working across engineering leadership, AI adoption, and architecture.
What I do
Fractional CTO
Technical leadership without the full-time hire. Roadmap, hiring, standards, and the calls that are expensive to get wrong.
AI orchestration & adoption
Help teams onboard AI into how they actually build and operate. Not a demo, a working practice.
Architecture design & review
Design systems that are dumb, easy to reason about, and decoupled enough to survive change. Or come in cold and tell you what's wrong with the one you have.
About
I'm Hasib. I care about quality, innovation and leadership. I solve the problems that are actually at hand, and I design solutions to be dumb, easy to reason about, within reach, and decoupled enough to survive change.
Eleven years across product engineering, architecture, and company building. I co-founded Craftsmen and helped grow it from zero to over $1M ARR and 80 people in under four years, twice named Best Startup by BASIS. We served broadcast and media-technology clients across Europe. Then I went independent, then spent a year at Automattic on WordPress and WooCommerce. Currently building something new.
Based in Dhaka, Bangladesh. Working with clients across the US and EU.
