Message

At VoiceScript, I designed and shipped a real-time messaging pipeline handling about 500,000 messages a day. I also built an email delivery pipeline and implemented Stripe webhook handling for subscriptions and payments.

I owned core frontend architecture and shipped features including API keys, invitations, and subscriptions. I directed development of Attorney Player, a real-time transcript viewer built with Next.js, with its MVP completed in one month.

At AllCart LLC, I built and led a five-person engineering team and delivered the core platform during its hot build phase. Earlier, at SkinSwipe, I built SteamFox, a Steam Marketplace price collector, and developed backend systems for Steam skin trading used by more than 100,000 active users.
