Manacher's Algorithm in Java: Linear Time Palindrome Search
Finding the longest palindromic substring is a classic interview problem. While the naive approach takes $O(N^3)$ and dynamic programming takes $O(N^2)$, Manacher's Algorithm achieves the same result in linear time ($O(N…

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.
