What I'm looking for

I'm looking to build maintainable, well-tested backend and cloud-native software that supports business transformation and customer-centric digital experiences.

At Atlassian, I build high-throughput Node.js and TypeScript services, improving API response times by 25% and automating data synchronization with AWS Lambda and API Gateway to reduce manual reconciliation by 40%.

Across consulting, healthcare, and remote cardiac monitoring systems, I’ve delivered event-driven integrations, ETL pipelines, secure OAuth authentication, and optimized databases while mentoring engineers and improving reliability, performance, and deployment speed.
