Engineering Writings
Technical Blog
Deep-dives and architectural notes on distributed systems, backend resilience, microservices, and cloud platforms.
Getting Started with Distributed Systems
A practical introduction to building distributed systems — from monoliths to microservices, consistency patterns, and lessons from production.
Observability That Actually Helped During Incidents
How Prometheus, Grafana, and correlation IDs turned our 2 AM debugging sessions from guesswork into detective work — and the dashboards that made the difference.
Designing a Configurable Workflow Engine
How we built a runtime approval engine that lets admins reconfigure 30+ workflows from the database — no code changes, no redeploys, and requests in-flight keep their original rules.
Building Offline-First APIs for Field Operations
How we designed sync APIs that let 7,000+ field agents work without connectivity — and what we learned about conflict resolution, data integrity, and edge cases.
The Circuit Breaker Pattern in Production
How a circuit breaker saved our payment system from cascading failure — and what I learned implementing it across three payment gateways.
