In fintech and e-commerce, every second of delay during onboarding equals frustrated merchants, overwhelmed support teams, and immediate revenue drop-off. When a prominent US fintech and e-commerce provider processing over $4B annually for 7,000+ merchants approached us at Sigli, they were facing this exact crisis. Their onboarding portal had hit a wall, paralyzed by two major blockers: 1️⃣ The Frontend Chaos: The customer-facing registration process was complex, opaque, and frustrating for new users. 2️⃣ The Backend Bottleneck: The server-side infrastructure was completely single-threaded, meaning it could only process one application at a time. As the merchant queue grew, the system choked. Sigli knew that fixing this was about deep infrastructure triage. We embedded the team to overhaul both sides of the application simultaneously: - re-architected the system to support asynchronous merchant validation (no more waiting in line); - seamlessly integrated third-party payment processors; - layered in robust fraud and cybersecurity protections without sacrificing speed; - owned the entire lifecycle from rigorous QA and user testing to ensuring post-launch stability.
