About

I am a backend-focused developer with nearly 15 years of experience, a strong PHP background, and a business-oriented mindset.

I have worked on the development, maintenance, and further evolution of high-traffic portals and the APIs serving them, while gaining a deeper understanding of the business and domain logic behind more than five portals.

My core strengths are modeling complex business logic, building stable integrations, and handling and optimizing data-heavy, database-centric systems.

On the backend side, I have worked alongside development teams of up to seven people in close collaboration with frontend, QA, BA, and PM, as well as earlier with finance, marketing, customer support, and PPC teams.

I am currently continuing to develop my knowledge in Node.js, NestJS, TypeScript, and Python.
