I help businesses build, improve, and maintain software and infrastructure they can rely on. Clients usually come to me when they need someone who can take ownership—not just complete isolated technical tasks. I help launch new platforms, modernize existing systems, improve reliability and performance, automate operations, and solve problems that are slowing the business down. My focus is always the outcome: stable systems, smoother operations, less downtime, easier maintenance, and a setup that can grow with the business. I'm based in Germany and communicate fluently in English (C2), German (C1), and Romanian (native). I also operate my own hosting infrastructure, which can be useful for development, staging, testing, and deployment when a project needs it. You can expect clear communication, realistic commitments, and dependable follow-through. I'm also available after delivery for ongoing development, maintenance, monitoring, improvements, and long-term technical support. If you need someone experienced who can take responsibility for the technical side and stay involved long-term, I'd be glad to help. less -
