I specialize in modern CMS ecosystems - particularly Craft CMS, Statamic, and ExpressionEngine - combined with frontend frameworks like Tailwind, Vue.js, React, Alpine.js, and Nuxt.js to create flexible and future-ready solutions. Over time, I have worked extensively on projects where performance, structure, and long-term maintainability matter more than just "getting it done." What I actually help with: ✅Building custom Craft CMS websites (including Commerce, modules & plugins) ✅Developing Statamic sites with clean, flat-file architecture ✅Maintaining and extending ExpressionEngine projects ✅Creating headless CMS setups with API-driven frontends ✅Migrating legacy or WordPress sites into scalable CMS platforms ✅Solving complex frontend/backend integration challenges How I approach development: I don’t just write code - I structure systems. That means: ➢ Clean architecture that other developers can understand ➢ Performance-first builds (Core Web Vitals matter) ➢ Minimal technical debt ➢ Thoughtful CMS setups for non-technical editors Tech I work with daily: ➢ Craft CMS, Statamic, ExpressionEngine ➢ Vue.js, React.js, Nuxt.js, Alpine.js ➢ PHP, Laravel ➢ REST APIs, Headless architectures ➢ Tailwind CSS, Vite, modern build tools I prefer working on projects where quality and long-term thinking are valued over shortcuts. If that aligns with what you need, feel free to reach out.
