What I'm looking for

I seek full‑stack roles in healthcare or supply chain where I can build scalable .NET/React solutions, lead integrations, and contribute to product and process design in collaborative, quality‑focused teams.

I am a full‑stack developer and industrial engineer specializing in scalable .NET Core and React/TypeScript applications for healthcare and supply chain domains. I focus on clean, performant code, maintainable architecture, and bridging technical teams with user needs.

I have built backend microservices (Entity Framework Core, .NET Core), Node.js/TypeORM integrations with Oracle and PostgreSQL, and responsive web and Electron desktop front ends. My solutions, including AstorePlus 3.0 and Magneto, have been deployed in multiple countries and used in dozens of hospitals.

I contribute to requirement analysis, process design, UAT coordination and system integration (HL7 via Mirth Connect), and prioritize UI/UX, database optimization and cross‑platform delivery to ensure reliable, production‑grade software.
