About Me

Hello, I’m Rohan Ray – Architecting Performance and Scale.

Welcome to roray.dev - my personal blog!

With over 17 years of hands-on experience under my belt, I am a dedicated software engineer specializing in high-performance, high-scale systems. My career has spanned demanding technical environments across Telecommunications, eCommerce, Retail, Healthcare, Banking, and Capital Markets.

My Core Focus: Performance and Scale

My true passion—and the focus of this blog—is tackling the most complex challenges in system performance and scaling. I thrive on designing, debugging, and deploying robust architectures that can sustain massive traffic loads and evolving business needs. This site is dedicated to sharing the advanced technical challenges I solve outside of my daily role.

My most significant technical achievement to date is the founding of recaho.com, a platform I built that successfully scaled to serve over a million Daily Active Users (DAU). It is a testament to the engineering principles I advocate.

Through this blog, I aim to share solutions and insights that can benefit others tackling similar high-stakes, high-scale engineering hurdles.

Technical Expertise

I possess deep expertise across a wide range of modern and specialized technologies, including:

  • Languages & Frameworks: Java, Go, Node.js, React.js
  • Cloud & Architecture: AWS, Azure, Cloud-native microservices, DevOps
  • Domain Specific: FHIR (Healthcare), ERP Systems, Electronic Trading Systems (using FIX Protocol)

Connect and Collaborate

I am currently based in Pune, India, and I am actively open to discussing consultation opportunities related to complex scaling and performance optimization projects.

If you are facing a critical performance bottleneck, planning a high-scale migration, or need to optimize an existing architecture, please feel free to reach out.

Beyond the Code

When I step away from the terminal, I focus on recharging:

  • Family Inspiration: My lovely daughter, Myra, keeps my mind agile. Her endless curiosity and quest for knowledge constantly inspire a renewed sense of learning.
  • Recreation: You can find me unwinding by playing FIFA on my Xbox or engaging in the strategic patience of a game of Snooker with friends.
