👋 Hi, I’m Atishay Jain

🚀 Backend Engineer | Distributed Systems Enthusiast | API & Platform Specialist

I’m a backend-focused software engineer with 4+ years of hands-on experience designing and building scalable, secure, and high-performance systems.

I thrive at the intersection of system design, clean APIs, and real-world production challenges.

Currently, I work on video intelligence platforms, central authentication systems, and high-throughput backend services used in B2B enterprise environments.


🧠 What I Do Best

  • 🏗️ Design scalable backend architectures (microservices, sharded databases, event-driven systems)
  • 🔐 Build authentication & identity systems
    (SSO, OIDC, SAML, Okta, Auth0, LDAP)
  • Develop high-performance APIs
    (handling millions of requests with caching & optimization)
  • 📦 Own systems end-to-end
    (design → development → deployment → documentation)
  • 🧩 Think extensibly
    (multi-tenant systems, multi-tournament logic, year-wise data models)

🏆 Highlights & Impact

  • 🥇 Best Performer Award at Awiros
  • 🏅 Exceptional Talent Creation Award
  • 🔐 Secured STQC certification by resolving critical cybersecurity gaps
  • 🔑 Independently designed & implemented a complete SSO solution
  • 📊 Built a high-performance Datalake microservice handling millions of requests
  • 🧠 Known for clean architecture, extensible code, and strong system design discussions

✍️ Developer Philosophy

“Good backend systems are invisible when done right — reliable, scalable, and boring in production.”
