Almost nobody plans for real usage. I have watched “perfectly designed” systems fall apart the moment real users, real data, and real business pressure showed up. This is what actually breaks, and how I fixed it.

Everyone was doing it. Six months later, delivery slowed, costs went up, and simple bugs took days to trace. Here’s what actually went wrong and how we fixed it without blowing up the product.

They lose it because their pricing is disconnected from value, risk, and effort. This guide explains how service-based IT companies can design pricing systems that lead to stable revenue and predictable profitability. Tech Business & Product Strategy https://www.iamabhishek.com/blog/how-to-build-a-profitable-service-based-it-company https://www.iamabhishek.com/blog/how-to-build-a-profitable-service-based-it-company Mon, 19 Jan 2026 17:41:41 GMT Starting a service-based IT company looks simple from the outside: get clients, deliver work, earn revenue. In reality, you face cash-flow traps, hiring mistakes, pricing confusion, and invisible scaling ceilings. This guide breaks down what really happens and how service businesses turn into consistently profitable companies.

Latency dropped, then quietly got worse. This is a real production bug breakdown of how a Redis cache invalidation mistake slowed critical pages and how I fixed it without rewriting the backend. Backend Engineering https://www.iamabhishek.com/blog/a-single-missing-database-index-took-our-app-from-120ms-to-4-8s https://www.iamabhishek.com/blog/a-single-missing-database-index-took-our-app-from-120ms-to-4-8s Mon, 12 Jan 2026 18:16:32 GMT This database performance issue didn’t look like a typical failure. There were no crashes, no alerts, and no obvious slow query warnings. Locally, everything felt fast, masking the missing database index that only impacted production. As traffic increased, query performance degraded, leading to rising latency and unpredictable response times. This is exactly how hidden indexing issues silently turn into major production bottlenecks.

It slowed down gradually, then fell over under load. The problem wasn’t traffic. It was invisible memory retention hiding inside “clean” Node.js code.
