Message

At OneData Software Solutions Pvt. Ltd, I led technical blueprints, frontend architecture, stack selection, and integration boundaries for enterprise applications from 2024 to 2026.

I designed decoupled data contracts between frontend applications and backend services across monolith, modular monolith, and microservices architectures. I also worked directly with client stakeholders to translate business needs into frontend specifications and drive feature delivery.

I adopted TanStack Query with Vite and used TanStack Query, TanStack Router, and TanStack Start together on my final project. I established local test automation with React Testing Library and Mock Service Worker to isolate frontend behavior and improve release confidence.

I'm building SlotSyncro, a timezone-aware scheduling platform, using Next.js App Router, TypeScript, PostgreSQL, and Prisma. It includes recurring availability, event types, slot calculation, conflict checks, direct booking, and CI coverage reporting.
