About Me

Building the Future with Code & Cloud

I'm Arumugam Maharaja, a backend developer specializing in Python and Go, with deep expertise in cloud-native architecture and AI/ML integration. With over 6.8+ years of experience, I have worked across oil & gas, energy, and telecom sectors delivering robust, scalable solutions.

When I'm not coding, I enjoy exploring new cloud services, contributing to open-source projects, and writing technical articles about backend engineering, graph databases, and AI in enterprise applications.

Mobile Apps (Deprecated)

Built some mobile apps related to mathematical calculations, visa guidelines, and quizzes in my early career out of curiosity using Flutter and Java, and deployed them on the Play Store and App Store. However, most of my apps are now deprecated as I don’t have time to update the libraries. Hopefully, I will take it up again in the future

Restaurant Manager as a Service (RMaaS)

Built a lightweight backend service in Golang exposing REST APIs for menu management, order creation & tracking, and MongoDB persistence. Features clean layered architecture with separation of concerns, making it modular and microservice-ready.
