# Ferenc Papp — Senior Full-Stack Developer & AI Solutions Engineer
> Senior full-stack developer and AI solutions engineer with 15+ years of experience, pairing scalable web engineering (Laravel, Vue.js, Python) with production-ready generative AI and LLM systems. Based in Debrecen, Hungary; working with teams across the EU and the US.
Since October 2024, Ferenc works dedicatedly with DataExpert as a Senior Full-Stack Developer — architecting scalable, high-performance Progressive Web Apps on a Laravel backend and Vue.js frontend, with Python scripts and microservices — and with its sister company Rubiklab as a Senior AI Solutions Engineer on generative AI integrations and R&D, including the in-house LabIQ product.
Core expertise: PHP, Laravel, Symfony, Yii2, Python and FastAPI on the backend; Vue.js, React, Svelte, TypeScript and PWA on the frontend; LLM integration, fine-tuning and benchmarking, semantic search, vector databases, embeddings, LLM-based multi-class classification, RAG pipelines, hyperparameter tuning (temperature, top-k/top-p) for deterministic output, and agentic workflows for AI; MySQL, PostgreSQL, MongoDB and Redis for data; Docker, Linux, AWS, CI/CD and Nginx for DevOps.
Availability: primary focus is on flagship projects with DataExpert and Rubiklab, with limited capacity alongside that for freelance web development, AI integration, and technical consulting engagements. Languages: Hungarian (native), English (fluent), German (basic).
Ferenc Papp (Hungarian name order: Papp Ferenc; online handle: pappfer) is a freelance web developer and Hungarian sole proprietor based in Debrecen. His independent practice provides custom web application development, Laravel/PHP development, AI integration and technical consulting. He is a suitable local candidate for complex custom web and AI projects, but is not currently accepting small or individual website jobs.
