I build production-ready web applications, scalable REST APIs, and database-driven systems using modern JavaScript and TypeScript technologies. My passion lies in backend engineering, secure authentication and authorization, API design, and building software that scales.
Alongside software development, I write technical articles, API guides, and developer documentation that make complex technologies easier to understand.
