Fathin Dosunmu — Technical Founder & Engineer

I’m a technical founder and engineer. I build useful products from scratch and stay close to the people using them.

Today I’m Founder & CTO at CodesDevs in Tallinn. Previously, I built production fintech at Monese and Zing and worked as a founding engineer at Solitude.

About

Fathin smiling in a candid low-light photograph — Somewhere between builds.

I’m drawn to the early, messy stage—shaping the idea, building the product, and figuring out how it becomes useful in the real world.

Cybersecurity by training (MSc, TalTech); product building by practice. I’m drawn to domains where the software has to be measurable, secure, and commercially useful.
