Senior WordPress Developer

Co-Founder

WordPress powered Websites and Apps, WP Plugins and eCommerce solutions

Web & Apps Developer

I’m a versatile Web Developer with a passion for blending technology and marketing to create impactful digital solutions. My expertise spans modern frameworks like React and Next.js, alongside deep experience with CMS platforms such as WordPress and HubSpot, where I currently focus my efforts. I’ve also worked extensively with e-commerce systems like WooCommerce and Shopware, giving me a solid foundation in building user-centric, results-driven platforms.

I thrive on efficiency, using automation tools like Zapier and n8n to streamline workflows and save time, skills I bring to every project. Working in marketing teams is where I shine, leveraging data to drive strategy and deliver value. I’m big on fast, meaningful A/B testing, think personalization and user experience tweaks alongside Technical SEO (also AEO/GEO)  to boost visibility, and discover positioning.

I also focus on optimizations and audits to keep platforms running smoothly and up to best practices. Plus, I’ve got hands-on experience helping marketing teams migrate legacy code, making those transitions as painless as possible.

Looking ahead, I’m excited to explore MACH (Microservices, API-first, Cloud-native, Headless) and DXP (Digital Experience Platform) systems to push the boundaries of digital marketing.
