Full-stack software engineer building resilient payments and GIS systems.
EstoniaWhat I'm looking for
I’m a full-stack software engineer who’s helped teams deliver during high-stakes transitions—most notably contributing to the core payments team during a major migration to Adyen and stabilizing legacy systems by resolving production bugs in critical payment flows.
In my earlier roles, I worked hands-on across BE and FE to migrate, develop, and expand software for a hospitality and tourism startup, focusing on high performance, maintainability, and scalable architecture (including optimizing database queries). I also supported close client relationships and provided technological consulting while aligning priorities.
Most recently, I spearheaded the development of over 10 GIS microservices from scratch, designing RESTful APIs and building geospatial data processing workflows to improve efficiency. I’ve also maintained a Europe-wide parking app with test-driven development and alerting, and I bring a strong engineering mindset using modern frameworks, cloud, and containerized deployment.
