Full-stack developer with 15+ years of experience, focused on Laravel and Vue.js, along with SQL, Docker, microservices, and REST API work. Most of my projects run end to end, so I'm usually involved in the architecture, the coding, the testing, and keeping things stable in production. I lean on test-driven development and try to keep the codebase clean and easy to maintain, so it stays pleasant to work with over time. I also work with LLM and AI driven features, and I use AI tools in my own day to day workflow. On one of my current projects I build agentic workflows and agent orchestration directly into the platform, so I'm comfortable putting LLMs into real production applications rather than just experimenting with them. Some recent work: a Kubernetes based microservices platform for a solar-panel rental business, a production planning system for a cardboard factory that schedules jobs around real machine constraints, and an event and congress platform covering registration, abstract submission, accommodation, RFID badging, and certificate generation. So far my Upwork contracts have all finished at 5.0, which I'm happy about. I mainly enjoy longer term collaborations where I can really get to know a product. If that fits what you need, feel free to reach out and tell me a bit about it. Core stack: PHP, Laravel, Eloquent, Vue.js, Inertia.js, Livewire, MySQL, REST APIs, OAuth2, Docker, Kubernetes, PHPUnit, Git, JavaScript, Angular, LLM Integration.
