OSAMA BARI / CTO

Chief Technology Officer · D24 Fintech Group · Dubai

I build regulated trading systems, and the web3 rails beneath them.

Matching engines measured in microseconds; exchanges measured in licences. Four regulated venues shipped across three jurisdictions — two ranked in the CER.live Top 10 most secure crypto exchanges worldwide — with a 40% cloud-cost reduction, a 15% year-on-year engineering-efficiency gain, and the 150-person organisation, in-house and offshore, that runs it all.

Profile

EXEC SUMMARY

Close to the code, accountable for the outcome.

I'm a hands-on CTO. For the last five years that has meant owning trading-platform and blockchain engineering as a founding technology leader — building matching engines, order management, market data, custody, settlement and on-chain economies from zero, across digital assets and traditional capital markets.

The part that compounds is the organisation: I recruited and led an engineering and product team of 150+ people within a year — an in-house core combined with offshore teams across countries and time zones — with the governance in place so every platform keeps scaling after launch.
