MySELLerCENTRAL

MySELLerCENTRAL is the platform I led at KAS Commerce. It gives merchants on the ONDC network a single console for catalogue management, inventory, pricing and fulfilment.

The hardest problem was onboarding: sellers arrive with thousands of SKUs in spreadsheets of wildly varying quality. I designed a bulk XLSX/CSV pipeline with per-row validation and category-aware attribute mapping that took listing velocity up 60x, then moved the heavy work onto queue-based parallel workers so a 50,000-row upload never blocks the request cycle.

On the protocol side I integrated the core ONDC APIs - /search, /select and /confirm - plus a logistics aggregation layer spanning 26+ providers that surfaces the cheapest and fastest option per order.
