Build Systems, Toolchains & Developer Infrastructure
Led a company-wide migration of 300+ services across two repositories to Bazel, replacing fragmented Nix, Docker, and Poetry workflows with a unified multi-language build platform spanning Rust, Python, C++, Go, and Erlang.
Worked on custom Rust toolchain and sysroot setup to support hermetic, reproducible, and stable builds across local and CI environments.
Designed and implemented dependency-graph-driven CI and build graph optimization across multi-language services, enforcing explicit dependency boundaries, improving reproducibility and cache effectiveness, reducing unnecessary rebuild scope, and reducing common CI paths from ~170 minutes to as low as ~7 minutes (incremental build).
Built shared Bazel rules, macros, and containerd-compatible local workflows, standardizing developer workflows and accelerating adoption across teams.
