Summary
🤩
Rockstar🎓
Top SchoolKhalid H is a senior backend engineer with 11+ years building high-throughput distributed systems, blockchain parsers, and custom frameworks—fluent in Rust, Go, Node/TypeScript and production tooling across Docker, Kafka, Redis and Postgres. He has shipped Lisk protocol and SDK work at Lightcurve and contributed to the popular Lisk SDK, and maintains Rust projects spanning zero-knowledge proofs, WASM tooling and Rocket-based APIs. Experienced in low-level Rust (unsafe, Tokio, async, cryptography) and practical integrations (gRPC, message brokers, Redis Streams, Elasticsearch), he repeatedly tackles large-file parsing, concurrent processing and real-time SSE/TCP services. Based in Vilnius, he pairs deep systems expertise with strong API and DB design skills, and a knack for turning complex blockchain and streaming requirements into reliable, testable services. An understated strength is his cross-language pragmatism—choosing the right tool (Go goroutines, Rust async, or Node workers) to maximize concurrency and operational simplicity.
