Summary
🤩
Rockstar🎓
Top SchoolAndré Silva is a seasoned backend software engineer with 16 years of experience building and hardening core infrastructure for blockchain and distributed systems from Porto, Portugal. He spent seven years at Parity Technologies contributing to Polkadot and Substrate, improving RPC/state APIs, consensus behaviors and node reliability—work that directly impacts production blockchain clients used globally. A pragmatic systems hacker, his open-source footprint includes performance-conscious numeric work in Scala's Spire, Ethereum tooling like ethabi and parity-ethereum, and lower-level protocol engineering across Polkadot projects. He pairs deep protocol and Rust experience with attention to testing, benchmarking and maintainability, and even contributes to tooling and build environments (QMK/Nix) where reproducible builds matter. Not actively looking for new roles, he nonetheless remains engaged in influential open-source projects and enjoys reducing complexity in core platform code.
