Senior Backend / Full Stack Engineer with 14+ years of commercial experience building business-critical web applications, enterprise systems and API integrations.
My primary expertise is PHP (Symfony & Laravel), JavaScript and SQL. In recent years I have also been expanding into Python, AI-assisted software development and LLM-powered applications.
I enjoy designing scalable backend systems, integrating external services, modernizing legacy applications and exploring how AI can improve both software development and the products we build.
