Aleksei Gubin

I’m a Senior Blockchain Developer with 7 years of software engineering experience, focused on full-node development, DeFi protocols, and high-performance blockchain infrastructure. I enjoy turning complex protocol requirements into reliable systems that can run at scale.

In recent work, I architected and developed a microservices backend for a multi-chain platform to enable real-time indexing and processing across 10 major blockchains. I also led from-scratch integrations and contributed to measurable product impact, including 50,000+ new MAU and $10M+ in new platform deposits.

Before that, I built a high-performance blockchain explorer processing 15+ blockchains at 5,000 RPS, and I implemented core Price Oracle functionality using Go and Solidity. I’ve also worked extensively with Cosmos SDK governance modules and protocol-level coordination, while delivering indexers that processed millions of transactions per day.

I’m hands-on across the stack—writing Go services and Solidity contracts, using security tooling like Slither and Echidna, and deploying with Kubernetes and CI/CD pipelines. I lead with architectural thinking, keep up with best practices, and thrive in remote collaboration with protocol designers, security experts, QAs, and frontend teams.
