What I'm looking for

I’m looking to join a team where I can build scalable APIs and full-stack products—especially secure wallet/payments and event-driven systems—work in Agile, and keep improving performance, reliability, and documentation while shipping high-quality releases.

I’m a Software Engineer (Fullstack) with 2+ years of experience building scalable backend services and full-stack applications. I focus on event-driven and distributed systems, wallet and payments solutions, and RESTful API development.

In my current role, I design and develop scalable enterprise web applications using React.js, Node.js, and PostgreSQL. I’ve built RESTful APIs serving over 200,000 monthly requests and improved performance by reducing API response times by 45%.

I’m comfortable delivering secure integrations, including authentication using JWT and OAuth2, as well as payment gateway and third-party API integrations. I collaborate with product, QA, frontend teams, and UI/UX to ship reliable, user-focused features in Agile and Scrum environments.

Previously, I worked as a Frontend Engineer supporting backend APIs with Node.js, fixing bugs, implementing new features, and creating responsive pages with HTML/CSS, JavaScript, and Bootstrap. I’m energized by continuous learning and bringing high-quality execution to every release.
