Rust John Basrai

Senior Software Engineer Rust & C++ · Systems & Distributed Architectures · High-Performance Applications

About Me

Senior systems engineer with 15+ years of experience building backend and distributed systems, currently focused on Rust for authentication infrastructure and secure, high-assurance services. I care deeply about architectural clarity, explicit boundaries, and automated testing.

  • 🌍 Yuba City, CA
  • 🤝 Open to Rust-focused backend and distributed systems work

Current Focus

  • tokn — OAuth2/OIDC/JWT authorization server in Rust, implementing RFC 6749/7636 with automated protocol testing (PKCE, token rotation, scope enforcement).
  • rtp-opus-streamer — real-time audio streaming system in Rust using RTP (RFC 3550) and Opus (RFC 6716), exploring resilience, observability, and behavior under network constraints.

📌 Writing & Talks

🔐 Project Spotlight — tokn

OAuth2/OIDC authorization server in Rust with PKCE, refresh token rotation, and automated security testing.

Highlights

  • RFC-compliant OAuth2 server with PostgreSQL persistence
  • JWT lifecycle management (RFC 7519)
  • Redis-backed token revocation and replay protection
  • 10 automated integration tests covering security edge cases
  • Clean architecture using EMBP and trait-based abstractions

Stack: Axum, PostgreSQL (SQLx), Redis, Argon2id, Docker Compose

🧩 Selected Projects

Repo Focus
axum-quickstart Async REST APIs in Rust with WebAuthn/Passkeys, PostgreSQL, Redis, Prometheus
cr8s Rocket backend with JWT auth, role-based access, SQLx migrations, full integration testing
zkp-cp Chaum–Pedersen zero-knowledge proofs in Rust (gRPC, tonic)
mempool-vortex Ethereum mempool monitoring and latency analysis in Rust

🛠️ Technical Focus

Systems & Architecture

  • Secure sandboxed execution (Linux namespaces, cgroups v2)
  • User-facing ingress, scheduling, and backpressure
  • Explicit control/data-plane separation

Languages & Runtime

  • Rust (async, networking, systems)
  • C / Modern C++
  • Python, SQL, WebAssembly

Infrastructure & Observability

  • PostgreSQL, Redis, Docker
  • Prometheus, Grafana, Loki

Testing & CI

  • Integration-heavy testing strategies
  • Security-focused test coverage
  • GitHub Actions & GitLab CI

📋 Architecture Patterns

Explicit Module Boundary Pattern (EMBP)

A documented Rust pattern for enforcing architectural boundaries while preserving refactor freedom.
