## About

```text
At Noble.codes, I own architecture and delivery, including a real-time moderation portal on WebSockets that cut review time by 40%. I also added Redis singleflight caching for ftw.riotgames.com under high load and connected six social platform APIs behind one normalized data model.

I built Poryv, a Telegram Mini App for fitness trainers, solo—from client and progress features to bot reminders and payments—and it’s live with its first trainers. At JustAnswer, I worked on conversion A/B tests that increased subscriptions by 7%, added Apple Pay, Google Pay and PayPal to checkout, and moved more than 30 legacy screens to React.
