I'm Floris, an independent contractor in Haarlem with 30+ years of programming experience. I've built e-commerce platforms and three open-source tools (Canvas, ObjectQuel, WakaPAC), and spent the last decade focusing on legacy modernization. I handle any complex PHP or JavaScript work — from greenfield development to transforming unmaintainable systems into maintainable, productive platforms.
I'm an independent contractor with 30+ years of programming experience across multiple languages. I've built e-commerce platforms and three open-source tools, and spent the last decade focusing on legacy modernization. You work directly with me — fast decisions, clear communication, no corporate overhead. I handle any complex PHP or JavaScript work, and I deploy Canvas, ObjectQuel, and WakaPAC on client projects when they're the right fit.
I've spent years building these three tools to handle the specific problems that come up in legacy PHP work. These are open-source tools I deploy when they fit the problem.
PHP framework for gradual legacy transformation. Handles mixed old/new code during migration, provides clean separation of concerns, and enables incremental refactoring without big-bang rewrites.
Visit WebsiteA domain-level query engine with ORM capabilities and an expressive query language. Makes complex database logic readable, supports temporal data and rich relationships, and minimizes SQL string handling.
Visit WebsiteJavaScript reactivity system for progressive front-end modernization. Update legacy interfaces incrementally without requiring complete rewrites or heavy framework migrations.
Visit WebsitePHP and JavaScript development, architecture, and modernization.
Transform unmaintainable PHP or JavaScript systems using Canvas, ObjectQuel, and WakaPAC or your existing stack. Extract business logic, eliminate deprecated dependencies, establish test coverage. Independent system assessment to identify bottlenecks and create realistic modernization roadmaps.
Work with your existing frameworks and codebases — Symfony, custom systems, or any PHP/JavaScript stack. New feature development, API design, complex database operations with intricate relationships, change tracking, query optimization. Front-end work with WakaPAC, jQuery, or vanilla JavaScript.
Security hardening: identifying and resolving SQL injection, XSS, CSRF, and insecure authentication. Performance optimization: profile slow systems, analyze database queries, implement caching strategies. Evidence-based improvements.
I started programming at age 9 with BASIC, moved through Pascal and C/C++, and have been working with PHP since version 5 and JavaScript since the early DOM days. I've built e-commerce platforms, custom CMSes, and spent the last decade focusing on legacy modernization. I understand old patterns because I've written them, maintained them, and refactored them. Canvas, ObjectQuel, and WakaPAC represent 30+ years of experience distilled into tools that work in practice.
