I’m a Senior TYPO3 and PHP Developer with 10+ years of experience building, upgrading, and maintaining scalable CMS platforms for clients across multiple industries. My expertise includes TYPO3 upgrades, custom extension development, Fluid/Extbase architecture, API integrations, performance optimization, and long-term CMS maintenance. I’ve worked on both legacy systems and modern TYPO3 implementations, helping businesses improve stability, security, and user experience.

Over the years, I’ve contributed to enterprise TYPO3 projects involving version migrations, custom backend modules, multilingual websites, third-party integrations, and frontend development using Vue.js. I focus on writing maintainable code, solving complex technical issues efficiently, and delivering reliable solutions aligned with business goals. I’m comfortable working independently, collaborating with distributed teams, and communicating directly with clients.

Currently, I’m expanding my expertise into AI Engineering and AI-assisted development workflows. I’m actively exploring automation, AI integrations, and modern developer tools to combine traditional web engineering with emerging AI technologies. My goal is to build scalable, intelligent digital solutions while continuing to grow as a modern software engineer.

My expertise includes:
• Developed and maintained enterprise TYPO3 CMS websites using PHP, TypoScript, Extbase, and Fluid.

• Led TYPO3 upgrade and migration projects from legacy versions to TYPO3 v6/v7/v8/v9/v10/v11/v12/v13, improving security, stability, and maintainability.

• Built custom TYPO3 extensions, backend modules, and reusable components tailored to client business requirements.

• Integrated third-party APIs, forms, payment systems, and external services into TYPO3 platforms.

• Collaborated with designers, frontend developers, and project managers to deliver scalable web solutions on time.

• Improved website performance, resolved complex bugs, optimized database queries, and enhanced deployment workflows.

• Assisted clients with troubleshooting, maintenance, and long-term technical support across multiple TYPO3 projects.

• Exploring AI-assisted development workflows and automation tools to improve productivity and solution delivery.

I am open to:
• Remote freelance projects
