ABOUT — MOHIT KUMAR

Systemsthat stayboringunder load.

I design and build backend infrastructure — distributed systems, async pipelines, and payment-grade APIs. Most of my work lives at the intersection of reliability, performance, and clean design — not cleverness.

BIO — JODHPUR, INDIA → REMOTE

I ship systems that hold under load — exactly-once payments, resilient delivery, sub-500ms reads. The principle is simple: exactly-once is a design property, not a retry loop. Prometheus metrics and Grafana dashboards decide what ships.

Currently going deep on caching strategies, system design, and scalability — and building distributed webhook infrastructure.

HOW I WORK

Boring under load
No surprises at 3am is the goal.
Exactly-once, damn it
Idempotency is the design, not the patch.
Measure, then claim
Prometheus numbers, not vibes.
