At an NDA B2B marketing-tech platform, I moved AI content generation to per-vertical batches on a Python vLLM service, cutting cost per generated post by 58%. I also split a process into nine deployable units and added tenant isolation with Postgres row-level security.
At CompleteSoft, I combined eight REST round trips into an Express gateway and made shipment updates live across more than 50 hubs. At Voypost, I rebuilt core parts of a mobile parking app and restored background beacon openings from 3 in 10 to 9 in 10.
