## About

```text
I've spent 15+ years building and supporting long-lived SaaS products, most recently at Railsware on a B2B SaaS application. I migrated a legacy frontend to React and supported modules including Settings, Scheduling, and Email and SMS campaigns.

At Function4, I developed an events management platform, delivering messaging, notifications, paid ticketing with Stripe, guest management, search, and an admin panel. I also migrated the frontend to Vue.js and introduced Scrum and Kanban practices.

Earlier at iStat24.com.ua, I rebuilt a call-tracking service on Ruby on Rails and PostgreSQL, developed CRM and telephony integrations, and built a client Android application. I've also interviewed and trained developers and coordinated small Agile teams.
