Systems engineer · 20+ years · C/C++ → Go → AI-integrated infrastructure

Most of my production code lives in proprietary repos — a decade at BlackBerry, earlier years at Nokia and Torch Mobile, and now an independent trading platform.

Independently designing and operating an AI-assisted algorithmic trading platform. A Go execution engine on a self-managed 5-node Kubernetes cluster, with Anthropic Claude integrated as a real-time research partner via custom MCP (Model Context Protocol) servers. End to end: infrastructure, application, gRPC services, and iOS / web / CLI clients.

• AI / LLM — Anthropic Claude · MCP servers · agentic tool-use patterns · pgvector
• Infra — Kubernetes (k3s) · Docker · gRPC · Traefik · Ansible · HA PostgreSQL · Gitea
• Observability — Prometheus · Grafana · Loki
• Languages — Go · C/C++ · Python · TypeScript / React

• BlackBerry / RIM — 10 years across the BB10 browser (WebKit), WatchDox secure-messaging infrastructure, and IoT platforms
• Torch Mobile & Nokia — early-career WebKit work on mobile browsers; authorized WebKit committer
• DataValet · Bluescape — Go backend and full-stack roles
