Owners manage members entirely through WhatsApp commands, and their members get reminded before a membership runs out. The same backend runs personal reminders in Hindi, Hinglish or English — even by voice note: GPT-4o-mini reads the intent, Whisper turns voice into text.

• Owner commands: ADD, MY MEMBERS, REMOVE, RENEW, BIZ STATUS, BROADCAST, with analytics for the owner
• Renewal reminders at 7d / 3d / 1d / expiry with DONE and SNOOZE buttons: 1,500+ sent at a 98% delivery rate
• Plans at ₹999 / ₹1,999 / ₹2,999 a month via Razorpay, a referral system and 5 approved Meta utility templates
• Privacy Policy, B2B Terms and a DPA live — accepted on payment, or signed as a PDF with the DPA SIGN command

All game logic is server-authoritative: every write goes through Postgres RPC functions, so simultaneous bids are resolved by the database, not the client. The timer lives in the database too, pg_cron sweeps expired lots every 5 seconds, and a dropped phone is back in the right state within 3 seconds.

• 11 Postgres RPC functions own every write; place_bid is atomic (row lock, base price, slot and budget checks), with row-level security on every table
• 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
• Host controls (skip, pause, 60-second undo), 16 formations with position fit, bots that play with the same budget and info, and a 1080×1920 result card to share

TITAN evolved from a Hinglish voice assistant into an Electron desktop companion. Its React workspace brings together conversation, reviewed memory, research, files, timers and a separate browser. Hold-to-talk gives each recording a clear beginning and end; durable work context keeps goals, resources and next steps across restarts. The earlier wake-word build remains in the development history below.

• Hold-to-talk with a ready chime, release-to-send and Stop-to-discard; typed input and optional wake mode remain available
• Persistent work context, an action journal and reviewed memory with correction and forgetting; interrupted actions retain an honest unknown state
• Research with sources, bounded file access, PDF exports and durable timers with pause and resume
• A separate browser profile with explicit form-submit approval and connection-time public-address checks; no silent direct-network fallback
• Sandboxed renderer, trusted-frame IPC, PIN sessions and lock revocation; revision checks reject stale responses after locking
