Background

About me

I'm a full-stack engineer and AWS-certified cloud architect. I've led requirements-to-delivery work on retail IoT platforms, facility management systems, SAP integrations and internal generative-AI tooling — combining Python/Java backends, Angular/Vue frontends and Infrastructure-as-Code on AWS. I hold 18 certifications earned over four years, including multiple AWS Associate-level credentials, and I'm now taking on select freelance and consulting projects.
