About Me
Who I Am
I'm Rishabh Singh, a full-stack builder from India obsessed with shipping products that solve real problems. I combine deep technical expertise spanning backend systems, frontend development, and AI/ML with an execution-focused mindset centered on user feedback and market traction.
My journey is defined by shipping—from shipping my first production app to deploying 28+ projects with real users. I've learned that great products come from ruthless execution, deep user understanding, and technical excellence.
When not coding, I'm building in public, exploring emerging tech, and collaborating with other builders to create products with real impact.

Professional Experience
SDE-I
Feb 2025 - PresentM2P Fintech
Delhi, IN
- Solved high cache I/O latency caused by frequent Redis access by introducing a layered caching architecture (Caffeine L1 + Redis L2 with cross-instance synchronization), serving hot data locally, avoiding network round trips, and reducing read latency from milliseconds to near nanosecond-level access.
- Designed and implemented end-to-end import/export for complex no-code workflows, handling 10+ dependent workflow components and leveraging Server-Sent Events (SSE) to stream large workflow payloads reliably, improving scalability, user experience and one click migration.
- Led root-cause analysis and remediation of a production-critical failure involving thread contention and Kubernetes pod starvation during concurrent file uploads, restoring availability, stabilizing workloads at peak traffic, and increasing upload success rates by 60%.
