System Design: Building a Distributed Configuration Platform
Most systems begin with configuration as a file. That works for a while. Then one service needs a database URL rotation without redeploy. Another wants per-environment rate limits. A third wants tenant-specific limits. A…

System Design: Building a Fraud Detection Platform
Fraud detection is not a single model. It is a decision system that has to operate under latency pressure, incomplete information, adversarial behavior, and messy business trade-offs. If the system is too loose, fraud lo…

Inventory looks easy until traffic spikes. A product has 10 units. Ten customers should be able to buy it. The eleventh should not. In practice, that clean rule gets blurred by carts, payment retries, partial failures, s…

About Me
Who I Am
I'm a Technical Lead / Architect at Redwood Software, with over 10 years of backend engineering across fintech, enterprise SaaS, and early-stage startups.
I've worked at Paytm, ServiceNow, Threado AI, Paysafe, Accion Labs, and TCS — building systems that process payments at scale, integrating enterprise platforms, and leading teams through complex data migrations and architectural transitions.
CodeSprintPro is where I share what I've learned from building production systems — the real patterns, the real trade-offs, and the decisions that only make sense once you've seen a system fail at 2am.
