Shipping live apps, frontend systems, and release-ready product surfaces.
Interface architecture, product framing, QA automation, deployment, and release polish — the app, the infra, and the story as one integrated system.
Consumer-Friendly Crypto Casino
A crypto casino built for play, not protocols. 30+ games — Crash, Dice, Mines, Plinko, Blackjack, Roulette, slots, and more. Instant deposits, live chat with rain rewards, a Discord bot linked to your account, tournaments, referrals, and a built-in multi-asset wallet. Fair by default, never a lecture.
Mystery TCG Pack Opener
Rippet turns card collecting into a fast browser loop: rip mystery packs, reveal five-card pulls, collect duplicates, claim daily shards, and sell cards back instantly through a rarity-floor market. A provably fair HMAC-SHA256 engine powers every rip.

Market tooling with faster information flow, stronger context, and real execution-adjacent depth. Board, wallet, Dex, room, company surfaces with quote preview, swap build, auth, bookmarks, and social tools.
