I've built production-grade SaaS platforms including OpsCore, a multi-tenant B2B operations platform with strict workspace isolation, transaction-safe workflows, and secure subscription management.

For OpsCore, I architected a service-layer backend, SSR-safe authentication for 100+ concurrent sessions, hierarchical RBAC, and Stripe checkout and customer portal flows. I also developed a glassmorphism interface with GSAP animations that reduced perceived page-load time by 40%.

On MediStore, I built a scalable pharmaceutical management platform with audit-safe inventory modeling, real-time order tracking, soft deletion, and data snapshotting. I designed a Prisma and PostgreSQL backend with relational integrity and validation for sensitive medical transactions.

I work across Next.js, React, Node.js, PostgreSQL, and TypeScript, with a focus on secure authentication, high-performance user experiences, and reliable system design.
