I'm developing Mail Connector, a web-based AI email automation platform for Gmail and Outlook. It features smart filtering, background task queues, real-time action execution, and automated deployment through GitHub Actions.

I developed LLIMO.CO, a SaaS platform for a US client, using Django and React, integrating Stripe payments, and launching it on AppSumo. I also built Verify, a phone verification platform with a public API, using React, NestJS, and the Telegram Bot API.
