- Work Pilots OySenior Python ArchitectDIGITAL & ITNovember 2019 - May 2023 (3 years and 6 months)Espoo, FinlandWe did a complete rewrite of their legacy system. I was responsible for the API, database, service, admin frontend.The API's response time decreased significantly from an average of 500ms to 100ms after the rewrite. Additionally, I developed a transactional memory cache to eliminate slow database calls, further improving the response time to 20ms. Finally, I ported the cache to Rust, resulting in less than 1ms performance for some endpoints.
