Summary
👤
Senior🎓
Top SchoolAleksandar Čekrlić is a Staff Software Engineer with eight years of experience specializing in blockchain, Web3 infrastructure, and high-performance distributed systems. He has led development of core peer-to-peer node software and networking layers using Go, libp2p and IPFS, and implemented consensus and resource-isolation solutions for decentralized compute networks. Aleksandar combines low-level systems expertise—from C-based cross-platform system software to cgroups/Job Objects—with cloud-native practices like Docker, GraphQL APIs, and observability via OpenTelemetry and Prometheus. A founder of a consulting practice and a key engineer on projects that integrated blockchain data into exchanges and analytics platforms, he’s as comfortable reverse-engineering APIs as designing scalable indexing services. Based in Serbia, he’s driven by curiosity and an engineer’s urge to “look under the hood,” often surfacing non-obvious performance improvements and resilience guarantees in production systems.
