I build distributed systems that are fast, reliable, and secure. As a Software Engineer at Clearmatics (London, Remote), I designed features for network topology, message sharing schemes, and participant staking/penalty mechanisms using Go and fault-tolerant consensus algorithms. I also restructured and optimized a message-sharing system—cutting network overhead by 90% via cryptographic aggregation and boosting network capacity by 400%.

I focus on performance and operational correctness in production-like environments. I designed a high-throughput PostgreSQL data-indexing pipeline, authored optimized SQL/indexing/schema changes to reduce dashboard latency by 30%, and resolved critical security vulnerabilities by debugging low-level cryptography incompatibilities while improving test coverage by 20%. Previously, at Latoken (Malta, Remote) as a Core Developer, I handled distributed-systems reliability (including DDoS and threshold public key encryption scheme issues), built fault-tolerant consensus persistence using RocksDB, improved after-failure sync speed by 20%, and optimized Web3 API execution/RPC responses to prevent node failure modes while increasing unit test coverage by 80%.
