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 -
