What I'm looking for

I seek Full Stack or Backend roles focused on web systems, API integration and automation within an international team that values clear communication, measurable impact, and opportunities to deepen technical skills.

I am a Full Stack developer with hands-on experience building web systems and automations using PHP, C#, JavaScript, Laravel, Angular and Spring Boot. I have worked on international projects, communicate fluently in English, and focus on API integration, process automation and delivering efficient front-end and back-end solutions.

In my roles I automated internal processes that improved operational efficiency and developed dynamic web pages integrated with MySQL databases. I have led social media operations, produced KPI-driven reports for global clients, and continuously expand my skills through courses in full stack development, cybersecurity and generative/responsible AI.
