What I'm looking for

I'm looking to build secure, scalable production systems where I can deepen my Java, Spring Boot, cloud, microservices, and DevOps experience while contributing through Scrum delivery, code reviews, and production support.

I've built Auradocs, an enterprise document management platform supporting clients with 5–10 million active documents. I delivered its dynamic storage layer across on-premises disks, AWS S3, and Azure Blob Storage, plus hybrid RSA/AES envelope encryption for 40 MB files in under five seconds.

At Auradot, I've also integrated Active Directory with Keycloak and OAuth2/JWT, built secure external document sharing serving 10,000+ documents monthly, and delivered real-time WebSocket notifications for 100+ concurrent sessions. I improved releases from around two days to approximately 1.5 hours through Bitbucket Pipelines, Docker, and automated AWS and Azure deployments.

Outside Auradocs, I've deployed and maintained a live job portal for an Australian recruitment firm and built microservices-based booking and photo studio management applications.
