Stefan Creanga

Senior Full Stack Developer. 10 years building scalable cloud-native platforms across healthcare, automotive, dental SaaS, and fintech. Remote contractor.

About

I design and build event-driven serverless systems on AWS, from data pipelines processing millions of records to real-time platforms serving thousands of users. I've led teams at Deloitte building the UK's COVID testing infrastructure, built Porsche's central data backbone, and now I'm shipping my own products under Raitech. I care about systems that are simple to reason about and hard to break.
