ERVIN VARGA

I built the GUFO ecosystem, a connected multi-tenant SaaS platform for hospitality and retail operations spanning ERP backoffice, Android POS, waiter and kitchen workflows.

Through GUFO, I design and implement APIs, database models, tenant-aware controls, third-party integrations, production tooling and deployment workflows. GUFO ERP Backoffice provides real-time sales visibility, inventory management, invoicing and Romanian ANAF RO e-Factura workflows, while GUFO POS Android, GUFO Ospatar and GUFO KDS keep ordering, payments and kitchen preparation synchronized.

I use OpenAI Codex and Claude Code daily for implementation, debugging, refactoring and architecture exploration, while retaining responsibility for reviewing and validating production code. My stack includes React, Vite, Node.js, Express, TypeScript, PostgreSQL, Prisma, Docker, REST APIs and async workers.

As Sales Director at POSHARD IMPEX, I work directly with customers to turn retail and hospitality operational problems into practical hardware, software and product requirements. I enjoy shipping useful products, learning by building and collaborating remotely.
