Software engineer
Fortune Zviregei.
I build interfaces for systems that never stop sending data.
I'm a frontend lead at Adtran in Gdynia, Poland, building the real-time interfaces engineers use to keep optical networks running. Since 2019 I've worked across the stack — React and TypeScript at the front, Ruby on Rails and AWS behind it — cutting load times, migrating billing to Stripe, and mentoring the engineers who pick the work up next.
