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 -

My background is chemical engineering, but my work has grown far wider than that. Clients bring me problems in data analysis, spreadsheets and dashboards, financial modeling, business development and sales outreach, lead generation, market research, technical and business writing, process automation, web and app development, graphic design and presentations, and engineering calculations. I take the time to understand the real problem first, then pick the right tool for it, whether that is Excel and VBA, Python, Google Sheets and Apps Script, Power Automate, Make, n8n, SQL, or a good old phone call and a well written email. Some recent work: a 32,255 SKU product catalog cleanup, a 23 sheet investment P&L model, a pricing engine covering 3,544 pharmaceutical products, a 26 region sales control tower with 1,624 live formulas, a construction schedule with Gantt tracking, outbound sales and partnership research for a US firm, and a long list of reports, decks and documents written from scratch. I reply within a few hours, I ask the questions nobody else asks, and I do not disappear mid project. If you want a short sample before committing, just ask. less -
