@AnuragThePathak

I engineer predictable, fault-tolerant backend systems. I focus on explicit boundaries, enterprise observability, and code that reads like it explains itself — simple by choice, not by limitation. Currently at Kotak, previously CNCF.

What I Believe

Predictability over magic

Frameworks should reduce boilerplate, not obscure control. Predictability means holding the entire execution path in your head.

Fearless code, paranoid tests

Tests must anticipate adversarial boundaries. Production code stays fearless — invalid states crash loudly to expose the root cause.

Readable by design

Types let me read code like a book. Every line earns its place — but I'll split one into three if clarity demands it.

Fail fast, fail clearly

"Move fast and break things" only breeds defensive code. Invalid states should fail immediately — clarity scales better than silent corruption.

Selected Work

Subscription Management Service

A production-grade Go backend focused on strict domain boundaries, resilient infrastructure, and observability-first design.

Enterprise Observability (LGTM & OpenTelemetry) 100% instrumentation coverage across HTTP handlers, Redis, MongoDB, and Asynq using metrics, structured logs, and distributed traces. Includes automatic trace-correlated slog logging and native W3C trace-context propagation across the Queue → Worker boundary.
Adversarial Testing Built around a defense-in-depth testing strategy combining closure-based domain mocks with real MongoDB Testcontainers. Query behavior is validated using poisoned decoys, maximum-collision sorting, ghost subscription detection, and vault-lock verification.
Resilient Infrastructure Implemented fail-open Redis rate limiting with atomic CompareAndSwap debouncing to preserve API availability during cache degradation without flooding logs.
Clean Architecture & State Machines Domain, Service, and API layers remain strictly decoupled through explicit contracts. Subscription lifecycles are governed by compile-time-safe state machines that make invalid transitions structurally impossible.

Things I'm Proud Of

Darcula: A Go-First Semantic Theme

1200+ Installations across VS Code & Open VSX

I built this out of pure ergonomic necessity. After migrating from IntelliJ to VS Code, the high-contrast, neon-heavy themes caused severe eye fatigue during long sessions. Because I was obsessed with the classic Darcula aesthetic, I engineered this theme to recreate that exact JetBrains-level polish. Optimized for Go, it leverages semantic tokens and a strictly constrained palette to eliminate visual noise. No eye strain, no distractions — just comfortable, predictable contrast.
