Hello, I'm
ARNAB SAHA
Senior Software Engineer at Apple
Crafting elegant solutions to complex problems โ from AI-powered data platforms to developer tools. IIT Dhanbad alumnus with a passion for systems that scale and interfaces that delight.
Design-minded software engineer focused on building beautiful interfaces and robust distributed systems.
About Me
I graduated from the prestigious Indian Institute of Technology (ISM), Dhanbad with a B.Tech (Honors) degree. My journey in software engineering has taken me through some of the world's leading technology companies โ from building microservices at Amdocs, to insurance platforms at Paytm, to AWS Connect at Amazon, to WinUI frameworks at Microsoft, and now to Apple.
I believe in building systems that are not just functional, but beautiful. Every line of code should serve a purpose, every interface should delight, and every system should scale.
"Aut inveniam viam aut faciam" "I shall find a way or make one"
