Nikita Mura

I’m a Senior Go Developer with 8 years of experience engineering high-load distributed systems—vector databases, real-time telemetry processing, and blockchain infrastructure. I focus on performance engineering and high-performance computing, combining zero-allocation Go techniques with SIMD/AVX-512, unsafe/mmap, and deep profiling with pprof and trace.

At Weaviate, I architected and optimized the vector search subsystem, implementing HNSW and vector quantization (Product Quantization) for billion-scale indexes. I improved P99 latency by more than 25% using Go assembly with SIMD, cut RAM consumption by nearly one-third through custom allocators and data-structure optimization, and engineered storage engine performance with LSM-trees, efficient compaction, and WAL handling.

I’ve also driven resilience and scalability in distributed and cloud-native environments: I implemented Raft and Gossip for cluster state management, and created a new sharding mechanism enabling stable operation of 64+ node Kubernetes clusters under write-intensive workloads. Previously at Shell, I raised uptime to 99.98%, processed nearly 4 TB/day without capacity increases, and sped up inventory event processing over 3× with concurrent services and SQL query optimization; earlier at SingularityNET, I built gRPC/gRPC-Web interfaces and Ethereum payment-channel infrastructure, reducing request-proxying latency by 20% and cutting gas fees by ~18%.
