Message

At Paribu AS, I led a 15-person team responsible for the trading and order management domains of a crypto exchange. I delivered regulatory data sync over AWS for legal reporting and a crypto/fiat staking system.

At Verve Group, I led two geo-distributed teams on a real-time bidding platform handling 4M+ QPS, and contributed to a 30% compute cost reduction. Earlier, I helped grow engineering teams from 5 to 20+ at UITSEC Technology Group and co-founded Codehane, a B2B legal tech platform serving 50+ law firms across Turkey.
