Rockstar🎓
Top SchoolSergey Levitin is a Senior HFT Developer with 14 years building low-latency, production-grade systems across finance and crypto, currently engineering an HFT engine, zero-copy WebSocket client and custom TCP stack using C++ and DPDK. He combines deep systems and Rust expertise—evidenced by active contributions to teloxide and a public interactive CV—with a track record of bootstrapping data pipelines and IaC-based infrastructure using Terraform and Ansible. Previously he led backend teams to deliver high-throughput exchange engines in Go and end-to-end payment and Lightning Network solutions at Xapo, including integrations, CI pipelines and smart-contract testing. Sergey is comfortable rewriting fragile services from first principles to regain reliability and test coverage, and has repeatedly built fast, secure crypto payment gateways and KYC/back-office platforms. Based in the Barcelona metro area, he blends hands-on low-level engineering with team leadership and pragmatic DevOps practices. A not-often-stated detail: he has implemented address-generation and protocol workarounds (BIP32-like for Libra) when no off-the-shelf solution existed, showing a willingness to invent where needed.
