Full-Stack Developer at EaseMyResearch, focused on backend engineering, distributed systems, and AI-powered applications. I'd rather solve a production problem — a cache stampede, a payment race condition, a queue that must never lose a job — than build another CRUD app.
- 🔭 Building production SaaS, payment infrastructure, and developer tooling
- 📦 Published my first open-source npm package (below)
- 🧠 200+ LeetCode problems · strong DSA fundamentals
- 💬 Ask me about caching, Redis, queues, or Node.js internals
- 📄 Resume · open to backend / full-stack roles
@nexocache/cache — a production-grade caching library for Node.js.
Most caching libraries solve how to cache. This one solves what happens when the cache breaks:
- Stampede protection — 10,000 concurrent requests for one expired key produce 1 database query, not 10,000
- Fail-open — Redis goes down, the app keeps serving; no 500s
- Distributed locking, tag invalidation, stale-while-revalidate, decorators for both legacy TS and TC39 Stage-3
- Zero runtime dependencies, dual ESM + CJS, 97% coverage plus an 80% mutation score, published with npm provenance from CI

Every "must not" in my code is a bug I found, measured, and fixed.
