What I'm looking for

I seek senior technical roles where I can design scalable systems, lead cross-functional teams, and drive cloud-native, data-driven solutions in collaborative, outcome-focused environments.

I am a proactive, result-driven Staff Software Engineer with over 10 years of experience across retail, e-commerce, and social commerce, working in both startup and enterprise environments.
I specialize in full-stack web and mobile development, cloud infrastructure, microservice architecture, data engineering and I consistently deliver scalable, resilient solutions that improve performance and user experience.

I have led backend and architecture initiatives using Java/Spring Boot, Python/Django, Node.js, Kafka and cloud platforms (Azure, GCP, AWS) and also built data pipelines, analytics and automation that enabled personalized experiences and operational efficiencies. I excel at guiding cross-functional teams, optimizing integrations, implementing observability and DevOps practices to support high-availability production systems.
