A builder of systems and the teams that run them.

Osama Bari is a Dubai-based technology executive and the Chief Technology Officer of D24 Fintech Group, where he leads engineering across the group's core trading technology — ATLAS, a C++ ultra-low-latency liquidity and matching engine; a white-label exchange platform delivered to external clients; and OFZA.com, a VARA-regulated digital-asset exchange.

A hands-on CTO with more than 14 years in software, financial technology and blockchain, he builds regulated trading systems from zero — matching engines, order management, market data, pre-trade risk, custody and settlement — and has delivered multiple regulated venues end to end across the UAE (VARA), India (FIU-IND) and Mauritius (FSC). Two of those platforms, OFZA.com and BitDelta.com, are independently ranked among the CER.live Top 10 most secure crypto exchanges worldwide.

His web3 practice runs just as deep: on-chain since 2017, he has built private blockchains, enterprise Hyperledger systems for supply-chain and trade finance, Solidity smart contracts for payments, escrow and asset issuance, institutional custody on MPC, HSM and multisig, DeFi integrations with MEV and bridge-risk mitigation — and RaceKingdom.io, a metaverse NFT racing platform with an evolving on-chain economy built on ERC-1155 and Soul Bound Tokens.

He is a builder of teams as much as systems: at BitDelta he joined with no team, platform or infrastructure and recruited an engineering and product organisation of more than 150 people within a year — an in-house core combined with offshore teams across countries and time zones — instituting DORA metrics, MTTR governance and structured handovers so platforms keep scaling independently after launch. He is a regular commentator in the fintech press and holds a BA from Sampurnanand Sanskrit Vishwavidyalaya with diplomas in Computer Science from NIELIT and NIIT.
