What I'm looking for

I want to build end-to-end products where I can design APIs, ship microservices, and deliver reliable frontends—using strong testing and CI/CD. I enjoy roles that value performance, GDPR/compliance thinking, and continuous improvement.

I’m a Full Stack Software Engineer with 8 years of project experience, specializing in Nest.js, PHP/Laravel, and modern UI frameworks. I’ve built and improved production systems and open-source platforms, including enhancing GDPR compliance, developing REST APIs, and boosting performance and reliability through thoughtful backend and frontend integration.

Most recently, I built the Open Journal Systems (OJS) backend using PHP, Laravel, Vue.js, Docker, and GitHub Actions—delivering 10+ Laravel APIs for GDPR workflows and reducing manual consent processing time by 30%. Previously, I helped migrate a monolith to microservices with Nest.js and improved deployment time by 45%, built microservices that increased responsiveness, and raised unit test coverage to 90% with Jest while automating delivery with CI/CD.
