Rockstar🎓
Top SchoolKostis Karantias is a software engineer based in Athens with 14 years of experience and a decade-plus focus on cryptocurrency systems, particularly wallet synchronization and cross-chain interoperability. He has driven both research and implementation: publishing papers and designing ledger-to-ledger protocols at IOHK, and contributing protocol-security work to the well-known Ergo client (including PoPoW validity checks and refactors). His background spans low-latency C++ services at Bloomberg, market-data and trading systems built with Go/NodeJS, and data-driven strategy analysis using Pandas and sklearn. Comfortable leading teams from whiteboard protocol design to production-grade code, he blends academic rigor with pragmatic engineering to tackle complex distributed-ledger challenges.
