Summary
🤩
Rockstar🎓
Top SchoolAleksandr Bukata is a senior software engineer based in Lisbon with a decade of experience building high-load distributed systems across fintech, music streaming, and Web3. He moved from backend roles at Tinkoff and Yandex — where he built notification infrastructure and features for a 26M-subscriber podcast platform — into Web3, delivering NFT indexing at Rarible and observability for Chainlink’s CCIP. Aleksandr specializes in Go and Java, distributed systems, and production-grade observability, and he led integrations that now drive top-tier CCIP volume while scaling automation across EVM and non-EVM chains like Solana and Aptos. A pragmatic engineer who reduces bus factor, he took projects from MVP to production (NFT stats, indexer features, Stripe billing) and contributes fixes and telemetry enhancements to the widely used Chainlink repo. He prefers remote or hybrid roles in Lisbon and brings a data-mining master’s background to systems design, which informs his emphasis on reliable, measurable production behavior.
