I independently designed and built a multi-tenant retail, restaurant ERP, POS, and e-commerce platform, from its APIs and database to its storefront and tablet app. It serves multiple tenants in production, and I shipped more than 30 production features and fixes.

I led its backend rewrite from NestJS to Go, building five gRPC microservices, and migrated the database to self-hosted PostgreSQL and PgBouncer with zero data loss verified across all tables. Alongside my freelance work, I deliver enterprise infrastructure solutions at Intellexi Networks, focusing on Nutanix and networking.
