Work Experience

Back End Developer at Nexters (G DEV)
August 20, 2025 - August 20, 2025
Based in Limassol, Cyprus, I work in a team focused on increasing new players' retention. I contribute to prototyping MVP features, validating them with A/B tests and analytics, implementing or discarding ideas based on results. Notable projects include live-ops improvements (new templating for repeated events), dashboards, and legacy code refactoring to a microservice architecture. I also developed simple web pages using Vue.js for lootbox openers simulator and QA checker, and participated in internal tooling for faster marketing splits. I contributed to end-to-end tests and integrated analytics data collection with RSD, and shipped lightweight frontend pages enabling manual Cron launches.

Participated in legacy code refactoring, and built a virtual bank emulator for fiscal data operations (e.g., Starrus).
