• Production system serving a UAE workforce client — 178+ employees across 6 companies, 50+ REST APIs, live since 2024. Built in Go using Chi + pgx + Neon PostgreSQL.
• Implemented 4-level RBAC (super_admin → admin → company_owner → viewer) with JWT auth and an InjectCompanyScope middleware that silently gates every query — a company_owner crafting a URL with another company's ID gets an empty response, not a 403.
• Designed the UAE document compliance engine as a pure-function package: ComputeStatus(expiryDate, graceDays, alertDays, docNumber, now) — status is derived at read time, never stored. No cron drift, no staleness, trivially testable. Covers 5 mandatory document types with configurable per-company fine schedules.
• Deployed on Render with multi-stage Docker builds, Neon PostgreSQL, Cloudflare R2 for file storage, and graceful shutdown with a 5-second drain timeout. Background goroutines handle scheduled compliance notifications.

• Built a Flutter app that downloads, loads, and runs LLMs entirely on-device — multi-model chat and image analysis without any cloud API calls.
• Owns the full model lifecycle: HuggingFace-gated download (idempotent, cancellable, progress-tracked) → load into memory (configurable max tokens, GPU/CPU backend) → session init with temperature and system instruction → streaming inference → dispose. Skips thinking tokens from DeepSeek/Qwen3.
• Separately deployed Ollama to a local Kubernetes cluster via Docker Desktop — 2 YAMLs (Deployment + Service), pulled qwen2.5:0.5b into pod, port-forwarded, and confirmed via curl against the OpenAI-compatible /v1/chat/completions endpoint.

• Contributed a Badge widget to StacDev/stac (786+ stars) — a server-driven UI framework that renders Flutter UI from JSON. Studied the existing model/parser architecture before touching a line.
• Built the Badge model with full JSON schema support for positioning, alignment, colors, and child widget composition, plus a custom parser for runtime JSON-to-Flutter widget conversion.
• PR #388 merged into production. Badge widget is now available to all Stac users.
