Senior Software Engineer II at Tembo
Brazil
Summary
🤩
Rockstar🎓
Top SchoolVinícius R is a Senior Software Engineer II based in Brazil with eight years of experience building fault-tolerant, low-latency distributed backends, primarily in Rust and TypeScript. He has delivered production Rust systems for payments, blockchain indexing (notably contributions to The Graph’s graph-node), and real-time AR backends, with a strong emphasis on performance tuning, reducing allocations, and idiomatic refactors. His work spans Postgres extensions, ECDSA/secp256k1 signing and nonce management, and latency-sensitive Redis-backed pipelines, demonstrating both security-conscious design and operational rigor. An active open-source contributor, he focuses on micro-optimizations that matter—replacing eager operations with lazy ones, removing unnecessary clones, and improving test coverage for CLI tools. He also mentors peers in Rust and has experience across full-stack tasks, from REST APIs to front-end TypeScript features. Colleagues would describe him as pragmatic, detail-oriented, and unusually attuned to tiny changes that yield measurable system-wide performance gains.
