Available to hire
I am a senior backend developer with over 20 years of experience in backend and full-stack development. I specialize in PHP, SQL, Delphi, and Visual Basic, and I bring solid frontend skills in JavaScript and jQuery. I have a proven track record of remote collaboration, legacy system modernization, and performance tuning. I’m looking for a remote role where I can contribute to scalable, maintainable systems within international teams.
In my career, I’ve consistently delivered robust backend solutions, migrated legacy systems to modern platforms, and optimized performance to reduce load times. I enjoy solving complex data and integration challenges, and I’m adept at working across time zones with diverse stakeholders to drive successful project outcomes.
