This looks like a great fit, I will build your multi-tenant reverse auction SaaS platform with PAN-based company registration, GSTN structure management, vendor registration with MSME status, RFQ module, real-time reverse auction engine supporting Open, Blind, and Rank-only modes with 2-minute auto-extension, and an admin dashboard with audit logging. For the real-time auction engine, I will use WebSocket connections with Redis pub/sub to broadcast bid updates to all participants under 100ms latency, with server-side bid validation that prevents race conditions when two vendors submit at the same millisecond. Questions: 1) Should the hybrid pricing (per-auction plus subscription) be managed through Razorpay, Stripe, or another gateway? 2) How many concurrent auctions do you expect the system to handle simultaneously? Ready to start whenever you are. Kamran

Hi, we can build a secure, scalable reverse-auction procurement system that works reliably for both MSMEs and enterprise buyers. We’ve worked on multi-tenant SaaS platforms, real-time dashboards, and systems with complex workflows, so we understand how critical performance, auditability, and real-time accuracy are in auction-based environments. Here’s how we’ll approach it: • Build a clean multi-tenant architecture so each company, GST structure, and vendor operates securely within isolated environments • Implement a real-time reverse auction engine with live bidding, auto-extension logic, and rank/blind/open auction modes without latency issues • Create structured company and vendor onboarding with PAN, GSTN, MSME status, and item registration flows • Develop RFQ workflows, NDA handling, and hybrid pricing models (subscription + per auction) for flexible business operations • Build a powerful admin dashboard with audit logs, activity tracking, and full operational visibility • Deploy the system securely on AWS with proper scaling, backups, and performance optimization We focus heavily on stability, security, and scalability — especially important for procurement platforms handling sensitive business transactions. We can start immediately — I will ensure clear, daily communication and fast turnaround. You’ll always know the exact progress. Let’s connect on chat so you can share your Phase-1 priorities, and we can plan a smooth and reliable launch.

Your reverse auction SaaS project needs a solid real-time backend and multi-tenant setup, and I have built similar procurement platforms that balanced multi-company user roles with live bidding features. To handle your auction engine’s open/blind/rank modes with 2-minute auto extensions, I suggest implementing a robust event-driven system using WebSocket and Redis to ensure smooth real-time updates and prevent race conditions. Have you considered how you want to handle auction timeouts if all bids come in just before the extension window ends? For the multi-tenant structure with PAN and GSTN validations, I’d design the database carefully to isolate company and vendor data yet allow shared access where needed, ensuring clear audit trails per transaction. I typically deploy such projects on AWS using ECS and managed Postgres, which simplifies scaling and maintenance. Would you prefer a containerized microservices approach for easier future SAP integration in Phase 2? I can deliver a fully tested, production-ready platform with admin dashboards, audit logs, and three months’ support, all deployed on AWS. Ready to start mapping out the architecture and set milestones to keep this moving forward quickly.
