Production SaaS for AI-powered resume tailoring. Event-driven background jobs (Inngest) run multi-minute LLM pipelines with step-level checkpointing; OpenAI Responses API with Zod-validated structured outputs; ~90% inference cost reduction via prompt-cache-optimized prefixes; middleware-enforced JWT auth for premium gating; 5-job CI pipeline with Dependabot and Sentry observability.
Production multi-tenant SaaS platform for fitness studio management. 99K+ lines of TypeScript, 500+ users, $20K+ CAD processed. Row-level tenant isolation via a scopedPrisma client; Square SDK with idempotent payments and per-studio credentials; AWS SES/SNS/AppSync for email, SMS and real-time messaging; a 5,000+ test Vitest suite and 70 Playwright e2e specs against every Vercel preview; branch-protected CI with shadow-DB migration checks and Gitleaks secret scanning.
Agentic legal associate for instant, cited access to Canadian law. A LangGraph state machine routes intent and runs jurisdiction-aware vector retrieval (provincial queries auto-merge federal law) over a 16,000-chunk corpus of seven Canadian statutes (MongoDB Atlas vector search, Google text-embedding-004), with Gemini 2.0 Flash structured outputs, multi-turn thread memory, and a draft-to-PDF pipeline for legal notices. FastAPI backend, Next.js 16 frontend. Built for Delta Hacks 12.
Event-driven microservices platform for remote multi-guest podcast recording and broadcast-grade mastering, extended with an automated post-production and publishing pipeline. Six services communicate over a RabbitMQ topic exchange with dead-letter queues, each built on a hexagonal architecture. WebRTC captures multi-track audio, uploaded to object storage in checksummed chunks. FFmpeg masters the result with EBU R128 loudness normalization and multi-track mixing, driven by an event-driven session state machine. faster-whisper produces word-level timestamps; AI generates show notes, chapters, and titles with a deterministic fallback; RSS 2.0 feeds handle distribution. Verified end-to-end against a Docker Compose stack.
3D-printed cable-driven robotic hand that mirrors real hand gestures in real-time using computer vision (MediaPipe + Raspberry Pi 5 + Arduino Mega + PCA9685)
