Real-time 2D virtual social platform
“Users control pixel-art avatars in tile-mapped rooms while video calling, screen sharing, and chatting. Deployed on AWS EC2 via Docker with a GitHub Actions CI/CD pipeline and zero-port SSM deployment.”
AI job aggregator · 12 sources
“Scrapes 12 sources (HackerNews, YC, LinkedIn, Wellfound & more) via Playwright. Scores listings on a 12-point calibration scale using a 4-tier AI fallback: Gemini → OpenRouter → local Apple MLX → heuristic — with circuit breakers and ThreadPool concurrency.”
AI-powered room & flatmate matching
“Real-time WebSocket chat (exactly-once delivery), BullMQ async scoring pipeline, Transactional Outbox notifications, circuit breakers, and full RBAC — deployed on Vercel + Railway.”
Privacy-first macOS voice assistant
“Press a hotkey → record speech → transcribe via Apple MLX Whisper (4-bit quantized) → optionally query a local Ollama LLM → paste directly at cursor via Quartz HID event injection. 2.4s dictation latency at 1.55GB peak RAM.”
Real-time carbon footprint dashboard
“Monitors CPU (per-core), GPU, memory, battery & disk — then calculates live carbon footprint. Features CPU time-delta idle detection with a 5-minute threshold, per-process sparkline trends, and a Tech-Noir glassmorphic design.”
