Summary
🤩
Rockstar🎓
Top SchoolDenis Serebryansky is a Senior Software Developer and Tech Lead based in Germany with a decade-long focus on high-load backend systems and blockchain-enabled trading platforms. He architected and built core services for a cross-chain CEX/DEX liquidity aggregator at Lumia, including spot and futures engines and DeFi integrations that helped drive $3–4.5M daily spot volume while eliminating on-chain infrastructure costs. His background includes low-level contributions to the Waves blockchain client (transaction handling, fee logic and order processing) and prior work on anti-fraud and big-data systems at Sberbank-Technology. Denis combines hands-on backend Scala expertise with Solidity smart-contract development, observability-first reliability practices (Grafana), and proven hiring and team-mentoring experience. Less obvious: he repeatedly optimizes financial and operational resource allocation—once increasing available liquidity by one-third through architectural and protocol changes.
