Summary
👤
Senior🎓
Top SchoolPeter Duijnstee is an independent software developer and freelance IT consultant with over two decades of hands-on experience and 14 years of focused professional engagement, specializing in Ruby on Rails and workflow automation. He helps organizations streamline business processes by designing and building tailored automation that reduces manual steps and improves accuracy, with clients ranging from crowdfunded microfinance (Lendahand) to travel marketplaces (Gites.nl). Peter has repeatedly delivered production-ready systems, including the initial MIS for investors at Intellecap (FundForge) and a multi-market holiday-home platform, showing strength in both greenfield projects and legacy modernization. Based in the Randstad, he blends deep engineering skill with practical business sensibility, often acting as the bridge between product goals and technical implementation. Less obvious: his long freelance tenure since 2000 means he’s as comfortable consulting on strategy and process design as he is on day-to-day coding and deployments.
