I have spent the last decade mastering the architecture of high-scale WordPress solutions. At Pluginslab, we don't just write code; we build infrastructure that grows with your business. Whether you need to optimize a slow store, build a SaaS platform from scratch, or integrate cutting-edge AI into your workflow, we have the experience to deliver. Our Core Focus Areas: - Performance & SaaS: We specialize in deep-dive audits for high-traffic sites. We analyze database queries, server configurations, and code bottlenecks to ensure your WooCommerce store runs at maximum speed. We also excel in building robust SaaS products. - Artificial Intelligence: We guide enterprise clients on AI strategy, implementing LLMs and automation to help you ship faster and grow smarter. - Modern WordPress & Mobile: We are experts in Full Site Editing (FSE) and Block themes, ensuring your site uses the latest standards. We are also fully qualified to deliver end-to-end native mobile apps (iOS and Android) with complex API integrations. I work closely with Nuno Areias, a Senior Backend and Android Engineer who has been with me for over 11 years. Together, we ensure that every layer of your stack — from the server-side database to the frontend — is handled by a senior specialist. We are fluent in English, German, Portuguese, and Spanish. Our goal is to work on solid, well-thought-out projects and build long-term relationships. * Enterprise-level Performance Audits & Database Tuning * AI Strategy, OpenAI/LLM Integrations, and Automations * Advanced WooCommerce (B2B, Subscriptions, Custom Checkouts) * WordPress Full Site Editing (FSE) & Block Theme Development * Native Mobile Development (iOS/Android) with API Integration * SaaS Product Architecture & MVP Development * External API Integrations & ERP Syncing * Complex Data Migration & Bulk Import/Export * Custom Payment Gateways & Crypto Implementation * Project Management for Enterprise-Scale Builds

Marcel developed my project as planned and as described in the scoping document even though I asked for some last-minute changes in the workflow. Marcel excels not only in his technical knowledge but also in his ability to understand the customer's needs and the user's point of view. I plan to start soon other projects with Marcel. Finally, I want to thank him for his patience and readiness to deliver beyond commitment.

Marcel was a pleasure to work with from the first message. I hired him for a paid trial on a WordPress build for my orthodontic practice and he delivered exactly what he said he would, on time, with documentation that was genuinely useful. What stood out most was the depth of his thinking. He didn't just build the page, he came back with a clear architectural plan for the broader project that included patterns I hadn't asked for but that made obvious sense once he laid them out. His delivery PDF was unusually thorough, with honest notes on every decision he made and why. Communication throughout the build was excellent. He was responsive, asked smart questions before assuming anything, and handled the technical side without making me feel out of my depth. I'd recommend Marcel to clients looking for a senior-level developer who treats the work seriously. Strong fit if you want a thoughtful build, not just a fast one.

Marcel helped us solve our issues and gave us options when we ran into a couple snags that worked even better. I would recommend Marcel and his expertise to anyone that wants a solid experienced developer to help problem solve and have an incident free project. Many thanks to Marcel for his communication and responsiveness.

Marcel was fantastic to work with once again. He quickly identified and resolved some critical performance issues that had been impacting our site, and took the time to clearly explain both the problems and the solutions. His communication was prompt, transparent, and easy to follow throughout the entire process. You can tell he really knows his stuff and cares about doing things the right way. Looking forward to working with him again on future projects.
