👋 Hey, I'm Mohd Ahsan

🚀 Backend & Cloud Engineer | Node.js · Java · DevOps | ~4 Years Experience

I’m a backend-focused software engineer passionate about designing scalable, high-performance systems.
I specialize in Node.js, Java (Spring Boot), and DevOps automation, with experience building distributed, cloud-native applications that handle thousands of requests per day.

Currently, I’m part of ONDC (Open Network for Digital Commerce), contributing to microservices, API design, and automation across AWS and GCP.


🧠 What I Do

  • Backend Engineering: Node.js, Express.js, Java (Spring Boot), TypeScript
  • System Design & Architecture: Microservices, REST/GraphQL APIs, Message Queues, Event-driven Design
  • DevOps & Cloud: Docker, CI/CD (GitHub Actions, Jenkins), NGINX, AWS EC2, GCP, Shell Scripting
  • Databases: PostgreSQL, MongoDB, MySQL, Sql Server
  • Frontend (for integration): React, Next.js

💼 Experience Snapshot

  • 🧩 ONDC (Open Network for Digital Commerce) — Designed & deployed production-grade Node.js and Java services, automated CI/CD pipelines, and handled server orchestration using NGINX & shell scripts.
  • 🧠 Wits Innovation Lab — Built REST/GraphQL APIs, implemented Prisma migrations, integrated AWS SDK & Firebase, and deployed multi-cloud applications.
  • 💡 ToXSL Technologies — Developed reusable backend APIs, MongoDB backup utilities, and converted static web pages into dynamic React components.
