About Me

Engineer by craft, researcher by curiosity.

Software Engineering undergraduate with one year of industry experience as a Trainee Software Engineer at hSenid Mobile Solutions. I build full-stack products with Java, JavaScript, TypeScript, Spring Boot, Node.js, React and Next.js, backed by REST APIs, Docker, Keycloak and MongoDB, MySQL and PostgreSQL. I have shipped chatbot-platform features, Chrome extensions, Electron desktop apps and authentication flows, and I also do machine-learning research on graph neural networks, plus concurrent programming and optimization-based projects.
