Work experience

Senior Software Engineer

from 03.2007 to 07.2026 (19 years 5 months)
Railsware, Дистанційно (IT)

Software engineer and architect with ~19 years at Railsware (2007–2026), a product studio and consultancy — so my work spans building Railsware's own SaaS (Mailtrap, Zealth) and delivering client engagements as part of Railsware's team (Calendly, BrightBytes, RatePoint, and more). I grew from a Ruby on Rails developer into a software architect and tech lead, and I've repeatedly been the "deferred-to" technical authority on architecture, performance, and scaling.
