At Skip, I build incentive, pricing, and courier-facing platforms used by millions of daily users. I own Java Spring Boot and Quarkus microservices, React and TypeScript interfaces, infrastructure, and delivery pipelines end to end.

I led a BigQuery integration that increased courier challenge upload capacity from 1,000 to 40,000 rows in under 10 minutes. I also re-engineered offer workflows with Temporal SDK and Apache Kafka, reducing peak-load latency by 40%.

Previously at Skip, I scaled challenge generation, migrated legacy EC2 workloads to ECS Fargate with Terraform, and improved API p95 latency by 35% through database optimization, DynamoDB redesign, and Redis caching.

I started building high-volume distributed Java services at Amazon and case-management platforms at [24/7].ai. Across these roles, I focus on reliable systems, practical automation, and shipping production features without sacrificing performance or observability.
