Summary
🤩
Rockstar🎓
Top SchoolAlexander Nemish is a pragmatic CTO and functional compiler engineer with 15 years of experience building high-assurance systems in blockchain, finance, and distributed architectures. He designed and implemented the Marlowe interpreter—the largest smart contract on Cardano—co-authored peer-reviewed papers on smart contracts, and contributed to Plutus tooling, reflecting deep expertise in programming languages, type theory and cryptography. A polyglot developer (Scala, Haskell, Rust, C++, TypeScript, Python, Java) who has delivered Deutsche Bank–level solutions with Akka long before mainstream adoption, he blends research-grade rigor with product-minded pragmatism. He leads by technical example, teaches advanced Scala, and shapes architecture for state-channel and exchange designs while keeping a keen eye on privacy and self-sovereignty. Notably, his curiosity extends beyond software: he’s an inventor and adventurer who built custom hardware (a GPS tracker for cutaway canopies), composes music, and co-owns a skydiving dropzone where he also automated operations. Based in Paris, he currently drives technology strategy at Lantr after architecting Cardano-based exchanges at Cosmex and core smart-contract work at IOG.
