I am a Senior Software Engineer specializing in backend engineering, distributed systems, and scalable software architecture.
I started my software engineering journey over 10 years ago with Java and backend development, and have since designed and
delivered production systems for both large enterprises and fast-moving startups.
My core expertise lies in Java, Python, distributed architectures, data-intensive systems, and cloud-native infrastructure. I work
with technologies such as Kafka, MongoDB, PostgreSQL, Docker, Kubernetes, and modern observability stacks to build reliable and
scalable platforms.
More recently, I have been focusing on AI/ML infrastructure — integrating AI capabilities into production systems and building the
backend, data, and infrastructure layers required to operate them reliably at scale.
I enjoy solving complex engineering problems where software architecture, distributed systems, data, and infrastructure come together.
