AI/ML engineer · production agents, realtime voice, applied ML, and AWS platforms

Website · LinkedIn · Email

I build software that has to work beyond the demo: AI agents, realtime voice systems, model-backed workflows, APIs, and networked products. At Tech 42, I serve as a primary implementation engineer across client systems on AWS, working from architecture through evaluation, deployment, observability, and handoff. I am an AWS Certified Solutions Architect – Associate.

Outside work, I build independent systems projects in Python, Go, Rust, and TypeScript. Skirk and twoman began as practical engineering responses to connectivity constraints affecting people in Iran; together, they have earned 950+ GitHub stars.

Selected projects

  • Skirk — A Go-first encrypted transport that exposes local proxy and VPN interfaces and moves TCP streams through a Google Drive mailbox.
  • twoman — A host-preserving relay for shared cPanel and managed CloudLinux runtimes, with Linux, Windows, and Android clients.
  • Calluwu — An open-source toolkit and portable Rust runtime for building realtime AI voice agents, with TypeScript SDKs and a browser WebRTC client.
  • Trajectory — A source-available Rust DNS-native transport with encrypted access, recursive-DNS paths, and CLI, desktop, and Android clients.

Engineering focus

  • Applied AI and ML: agentic workflows, RAG, realtime voice, computer vision, evaluation, and observability
  • Backend and cloud: Python, FastAPI, AWS, distributed systems, APIs, and production delivery
  • Systems engineering: Go, Rust, networking, protocol design, and cross-platform clients

I also contribute focused improvements upstream. JuliaLang/julia#58181 is a merged REPL improvement that preserves and displays the input alias used for a character.
