Real-time multiplayer game

A live football player auction where 2–10 friends bid from their own phones — synced in under a second. Join by link, nickname only.

• 678-player pool from a Python pipeline over Kaggle FIFA 20 → EA FC 24 data and Transfermarkt values, 110 curated legends, photos via the Wikipedia API, and its own rating formula
• 431 tests across four layers: 165 pgTAP, 173 Vitest, 13 Playwright E2E (5 simulated phones bidding at once) and 80 pytest

Hindi / Hinglish voice assistant

A JARVIS-style assistant for Windows: say "Hey Titan" in Hindi, Hinglish or English, and it does the job on the laptop — then answers in English.

• Three-lane LLM fallback — NVIDIA (Llama 3.3 70B), then Groq, then Gemini 2.5 Flash — switching silently when one fails
• Wake word "Hey Titan" with Levenshtein fuzzy matching for mishears, barge-in, and semantic turn detection for English and Hinglish
• Actions: open and close apps, search sites, play on YouTube, web search, weather, file search, volume, lock, sleep, screenshots — each reports success or failure out loud
