└─────────────────────────────────────────────────────────────┘

hey, I'm Arshdev Singh 👋

I build things for the internet — mostly the parts you don't see.
Distributed systems, event-driven architectures, and the occasional rabbit hole (pun intended, RabbitMQ is real).

---

🧠 What I actually do

I'm a full-stack engineer with a strong pull toward the backend — the kind of engineer who loses sleep over message delivery guarantees and gets unreasonably excited about distributed system patterns.

🚀 Things I've built

🔥 Iffy — Blind Dating App

Because love is more fun when there's a message queue involved

A high-concurrency dating platform with a microservices backbone. WebSocket chat that held 200+ simultaneous connections without breaking a sweat. A two-phase media upload pipeline that kept storage lean with automated orphan cleanup. Built to be fast, fault-tolerant, and surprisingly smooth.

📦 Resilient Message Handling Architecture

Zero message loss. No, seriously — zero.

A deep-dive into distributed reliability. Implemented the Outbox-Inbox pattern across 3 microservices to guarantee exactly-once semantics. Layered in a 3-stage fault tolerance pipeline: immediate retries → exponential backoff → dead-letter isolation. The kind of system that doesn't panic when a service crashes mid-flight.

📊 By the numbers

⚡ A few fun facts

• 🧩  368+ LeetCode problems — graphs and DP are basically therapy at this point
• 🐇  I've named more RabbitMQ queues than I'd care to admit
• 📡  Genuinely fascinated by what happens at the boundary between reliable and unreliable systems
• ☕  Debugging is just reading the stack trace at the right zoom level
