Learn //Build //Share
Hello! I'm Rahul Aher, a Senior Software Engineer with 7+ years of experience architecting high-performance enterprise systems. Currently at ZEMA Global, I lead technical initiatives and design scalable digital architectures. I recently completed my Master of Science in Computer & Software Engineering from Scaler School of Tech, focusing on distributed systems and advanced system design.
My engineering philosophy is anchored in the cycle of Learn, Build, and Share. From my journey through Morningstar, EPAM, and BTS, I've learned that true expertise isn't just about writing code—it's about understanding fundamental principles, building resilient solutions for 180k+ users, and sharing that knowledge to empower the wider developer community.

Learn
Mastery is a continuous journey. Having completed my Master of Science (CS) while leading architectural migrations at scale, I distill complex distributed systems, HLD/LLD patterns, and advanced engineering concepts into actionable courses designed for real-world application.
Build
I build with purpose and pragmatic scalability. From leading high-stakes React migrations for enterprise platforms to engineering mission-critical workflow monitoring tools, I transform ambiguous business needs into scalable, performant, and maintainable systems.
Share
Knowledge multiplies when shared. Whether it's through winning SPOT awards for developer-centric innovation or publishing technical deep-dives on Full-Stack leadership, I am dedicated to sharing insights that foster a culture of excellence and community growth.

Projects - Building
“Code with clarity. Design with intent.
Deliver with impact” — Dave Ackerman
Chat Application with NodeJS, Angular, and Ionic
This Full-Stack Real-Time Chat Application demonstrates how to build a fully functional web and mobile chat app using modern technologies like NodeJS, Angular, Ionic, and MongoDB. The app allows users to engage in live conversations with real-time messaging, upload images, and interact with others via a seamless, interactive interface across both web and mobile platforms.
Dating Application with .NET Core and Angular
In this project, I built a dating application using ASP.NET Core for the backend and Angular for the frontend, creating a full-stack solution that enables users to interact and connect in real-time. The app offers various essential features for a dating platform, such as user authentication, profile management, private messaging, and real-time notifications.
RDS (Design system): NPM Package for Vue Projects
Consistency and standards are important for building a unified design language and help the user know what to expect from our product and how to use it. However, this does not mean sacrificing the user experience. In this sense, the context and needs of our users are priorities when developing our solutions.

Clean Code Tips I Learned from Senior Engineers
Being good at coding and writing good code are two different skills. I learned it the hard way after one of my pull requests at Amazon received 30+ comments.
5 Books Every Software Engineer Should Read (at least once)
During my Software Engineering career, I have come across and read many coding and software engineering books, but there are a few that I keep coming back to and try to re-read them every year.
