About Me

17+ years building web products that scale: from agency projects to a psychometric SaaS serving HR teams across Europe. I design robust APIs and modern interfaces that deliver real business value.

Robust Back-end: Laravel, Symfony, PHP at expert level. REST API design, async processing with Redis/RabbitMQ. Led the migration from monolith to 10+ microservices at Central Test: +45% scalability gain. Self-taught in Python since 2025: FastAPI, WebSocket, JWT, multi-tenant isolation, AI/RAG integrations.

Python & AI in Practice: Built Mini Trello (FastAPI, WebSocket, real-time task management, multi-tenant isolation) and a Genealogy Tree API (FastAPI, SQLAlchemy 2.0, hierarchical data modelling), two self-initiated projects to deepen hands-on Python expertise and AI/RAG integrations.

Modern Front-end: Vue 3 and React (TanStack Query, Zustand, Zod). Meta-certified Front-End Specialization. Focused on UX, performance and accessibility.

DevOps & Quality: Docker-first workflows, Kubernetes, CI/CD. Testing culture: PHPUnit, Jest, Cypress -45% critical anomalies on production systems.
