What I'm looking for

I'm seeking Software Developer opportunities in Australia where I can apply backend engineering, database architecture, PL/SQL, ETL, and ERP development experience to deliver measurable business value.

I've built and maintained enterprise ERP systems for hospitals and pharmacies, including DrHOMS, with patient management, billing, pharmacy, and reporting modules.

At Midas Technologies, I lead ERP development, design Oracle and PostgreSQL schemas, build PL/SQL procedures and ETL processes, and improve reporting through indexing and query optimization. I also lead developers, support backup and recovery, and contribute to Agile planning and production deployments.

At Dhi: Solutions, I developed web-based healthcare ERP modules using Java, JSP, and Hibernate, translating stakeholder requirements into scalable backend and reporting solutions.

I'm focused on delivering reliable database-driven applications, from transactional processing and data migration to performance tuning and client support.
