About

Turning complex ideas into practical, innovative solutions.

As a software developer, I thrive on turning complex ideas into practical and innovative solutions. My expertise lies in full-stack development, with hands-on experience in building web and desktop applications that are not only functional but also user-friendly. I have worked extensively with technologies like Vue.js, React, Symfony and .NET to create applications tailored to diverse client needs.

With a strong foundation in JavaScript, PHP, CSS and C#, I am equipped to handle both frontend and backend development. My projects often involve integrating modern frameworks, ensuring responsive design, and creating scalable, reliable systems. I leverage my knowledge of database technologies, including MySQL, MariaDB and SQLite, to build robust data-driven applications.

I am proficient in using Docker for containerized application development and deployment, and I bring expertise in both Linux and Windows environments. With experience in cloud platforms like Azure and Google Cloud, I create accessible and scalable solutions for modern-day challenges.

I work hands-on with modern AI tooling — integrating LLMs into production workflows, orchestrating agents, building retrieval-augmented systems, and shipping features powered by the OpenAI, Anthropic and Google AI APIs. I see AI not as a trend but as a force multiplier for building faster, smarter and more capable software.
