01Who I am

About

Software Engineer with 2.5 years of hands-on and 2 years of freelance experience building responsive and scalable web applications using modern front-end and back-end technologies. Proficient in Java, JavaScript, React/Next.js, Node.js, Spring Boot, Flutter, React Native, MongoDB/SQL, and CI/CD pipelines, with a solid understanding of microservices architecture and Linux system administration.

Outside of building apps, I've tackled a range of freelance projects: from creating full-stack solutions to writing Linux tutorials and technical docs that even beginners can follow. Whether it's debugging a tricky API or explaining cron jobs to humans, I'm all about making tech work and make sense.
