What I'm looking for

I seek backend or full-stack roles focused on API design, performance optimization, and scalable web systems within collaborative, Agile teams where I can grow technically.

I am a junior software developer with hands-on experience building backend systems, RESTful APIs, and full-stack web applications using Node.js, JavaScript, and TypeScript. I have delivered hundreds of client projects and improved operational efficiency through automation.

My professional work includes contract backend development for e-commerce platforms where I reduced API response times by 25–30% and integrated databases with efficient caching strategies. I focus on performance, security (JWT/OAuth), and reliable frontend-backend integration.

I am proactive, test-oriented, and collaborative, experienced with Agile/Scrum workflows, unit and end-to-end testing, and Linux/Git-based development environments. I enjoy solving problems, optimizing systems, and building scalable solutions.
