At AndSoft, I built and optimized a .NET REST API for QR-code recognition. After addressing barcode-library memory leaks and optimizing garbage collection, I reduced CPU utilization from ~100% to <10% at the same workload and restored processing of all incoming files.
I also introduced reusable NuGet packages across projects and built a bidirectional Canias integration microservice for driver profiles and accounting data. I established CI/CD for new solutions and deployed services on Azure.
At Vexcash, I led a team of 4–7 developers and guided the extraction of business capabilities from a monolith into microservices. I also established CI/CD, helped achieve 80% unit-test coverage in new projects, and developed a centralized logging system that cut costs by 14%.
At Godel, I led development on reed.co.uk and implemented selected methods for its CV Comparison Service. I optimized location lookup, making searches three times faster and improving location-matching accuracy by 20%.
