The exact pipeline I use: migrations without locks, health-checked deregistration, automated rollback on p99 regression.
Multi-Tenant SaaS System Design: Silo vs Pool, and the Hybrid I Recommend
Tenant isolation strategies, Postgres row-level security, per-tenant rate limits and billing guardrails from a platform serving 1.2M users.
Vue 3 vs React 19 in 2026: An Honest Take After Shipping Both
Composition API vs Server Components, Signals vs Zustand, hiring pools and migration costs. No fanboyism, just production trade-offs.
Notes from 10+ years of breaking (and fixing) production.
I'm Padam Shankhadev, a full-stack engineer and architect. This blog is where I document what actually worked — cache hierarchies, queue designs, query plans, and frontend budgets — so you can skip the outage that taught me.
Every article includes real numbers, real trade-offs, and copy-pasteable patterns from systems serving millions. No tutorial-hello-world fluff — just the decisions I'd make again on a Monday deploy.
