What I'm looking for

I seek senior engineering roles building scalable, cloud-native systems with cross-functional collaboration, measurable impact, and opportunities to mentor and improve platform reliability.

I am a senior software engineer with extensive experience building scalable, event-driven systems and customer-facing web platforms. I have led architecture and implementation efforts across inventory, logistics, order processing, and pricing systems using Java, Spring Boot, Kafka, Python (FastAPI), React/Next.js, and TypeScript, delivering measurable improvements in throughput, reliability, and conversion.

I have driven cloud-native deployments on AWS with Docker and Kubernetes, mentored junior engineers, and partnered with product and operations to align engineering work with business goals. My work has reduced processing delays, lowered failed retries, improved inventory synchronization, and increased average order value and repeat purchases through personalization and performance optimizations.
