What I'm looking for

I seek a collaborative, security-conscious engineering role focused on backend systems, automated testing, CI/CD, and opportunities to mentor and modernize legacy, regulated SaaS platforms.

I am a senior software engineer with over nine years delivering enterprise-grade, regulated SaaS solutions within Agile SCRUM teams. I focus on maintaining and modernizing long-lived business-critical systems while improving performance, reliability, and code quality.

My technical expertise centers on Delphi and Object Pascal, supplemented by Python, C#, .NET, JavaScript/TypeScript, and C++. I design and implement backend services, RESTful APIs, and database-driven applications using PostgreSQL, MongoDB, MySQL, and SQL Server.

I champion automated testing and CI/CD—raising unit test coverage from about 60% to over 85% and implementing GitHub Actions and Azure DevOps pipelines to increase release frequency. I also drive secure coding practices, input validation, and audit logging to meet compliance requirements for regulated platforms.

As a collaborative contributor and mentor on remote teams, I partner with Product Owners on story sizing and acceptance criteria, improve sprint predictability, and reduce onboarding time for new engineers. I deliver production-ready solutions with an emphasis on maintainability and measurable improvements.
