About

Experienced software developer with a strong foundation in backend development and system design. I’ve worked across a diverse tech stack including Java, Spring Boot, Python, Django, Kafka, Elasticsearch, Redis, MongoDB, Kubernetes, and Docker. Known for bringing high energy to teams and projects, I naturally gravitate toward taking initiative—whether it's leading new development efforts, driving cross-functional collaboration, or stepping in to solve critical challenges. I enjoy being a generalist with a specialist’s depth, and I thrive in environments where I can learn quickly and contribute meaningfully. Always up for a new challenge, I value working on impactful products and with people who care deeply about their work.
