During May 2025, work focused on enhancing the major/traefik repository by developing a rate limiting middleware feature in Go. This feature introduced a per-middleware scoped rate limit counter, which keys the counter by both the source and the middleware name. By doing so, it enabled independent and granular rate limits for each middleware, effectively preventing cross-limiter interference and improving tenant isolation. The implementation aligned with the existing rate limiter architecture, minimizing integration risk while increasing observability and testability for per-middleware quotas. The work demonstrated skills in backend development, API gateway design, and advanced rate limiting strategies within distributed systems.
