Backend Engineer • Distributed Systems • Node/TypeScript

I build backend systems with a focus on clean architecture, reliability, and scalability.
Recently worked on real-world event-driven workflows: queues, DLX routing, retries, schedulers, payments, pipelines, and CRM workflows.

• Open-source Job Runner — distributed workers, DLX, retries, backoff, heartbeats, logs
• Case studies on real backend problems (queues, APIs, webhooks, scaling patterns)
• Improving skills in WebSockets, streaming systems, and infra fundamentals

• Languages: TypeScript, JavaScript, Bash, GO (learning)
• Backend: Node.js, Express,
• Databases: PostgreSQL, MySQL, Redis
• Messaging: RabbitMQ (DLX, TTL, retries, schedulers), Streams (learning)
• Infra: Docker, Nginx, AWS basics
• Other: REST APIs, authentication, payment flows, multi-tenant systems

A distributed job execution system with:

• Worker registration & heartbeats
• DLX + TTL based retry & scheduling
• Structured logs + status tracking
• Multi-tenant execution model

• Lead scoring engine
• Deal probability engine
• Webhook pipeline
• Payments + Razorpay subscription workflows
• Queue-backed notification system

I share backend engineering insights on:

• Distributed systems patterns
• Real debugging stories
• Queue design (DLX, retries, idempotency)
• Webhooks & async workflows
• System design fundamentals

I enjoy diving into system internals and simplifying complex architectures into practical, production-friendly solutions.
