At Reactron Technologies Oy, I designed and maintained AWS microservices for a subscriptions platform, integrating RocketGate payments and automated chargeback handling. The systems I worked on processed 10,000+ transactions and $1.5M+ in revenue a month.
I built an admin and billing dashboard with React, NestJS, and Java Spring Boot to manage subscriptions, transactions, and business contracts. It reduced manual work and improved internal monitoring.
I also developed web and mobile applications for a content-sharing platform, including media uploads to AWS S3 and a console used by internal teams. For a mobile advertisement platform, I refactored legacy software and added analytics and push notifications, contributing to its redeployment and higher user engagement.
Since December 2025, I’ve been building and open-sourcing transform-cgf, a Python toolchain for converting CryEngine assets that was adopted for producing new in-game skins in production.
