I'm a software developer focused on backend and APIs, interested in building reliable, well-structured systems and understanding how things work under the hood.

My work is mainly centered around TypeScript, Node.js, and Python, where I build RESTful APIs, data pipelines, and small systems-oriented projects. I enjoy working close to the backend fundamentals, practicing algorithms, and contributing to open-source communities.

• Designing and implementing RESTful APIs with Node.js and TypeScript
• Building backend services with authentication, persistence, and basic security practices
• Creating data pipelines and automation scripts in Python
• Practicing algorithms and data structures, including implementations in C
• Containerization and deployment using Docker and Linux-based servers
