What I'm looking for

I seek a collaborative, Agile team-focused role where I can build robust backend systems, mentor peers, work with modern stacks, and deliver high-quality, testable software.

I am a software engineer with 6+ years of web development experience, focused on backend systems and full-stack delivery. I thrive in Agile teams and prioritize clean, maintainable code guided by DRY, KISS and separation of concerns principles.

I have refactored legacy APIs for readability and extensibility, designed and optimized SQL and NoSQL databases, and implemented job processing using Hangfire. I have hands-on experience with .NET, Spring Boot, Java and Angular, and I write unit and integration tests to maintain high quality.

My work has included designing authentication/authorization with JWT, integrating third-party payment APIs, conducting R&D (including a language translation tool and GDPR compliance research), and delivering CI/CD deployments. I have achieved test coverage above 90% in past projects.

I am organized, adaptable, and enjoy mentoring colleagues and performing code reviews. I look for collaborative teams where communication, technical excellence and mutual support drive impactful products.
