Leading Tech Companies
Hi, I'm Arvind Abraham, a Senior Software Engineer who believes technology is more than just code. It’s the art of turning data into decisions, ideas into impact, and complexity into something beautifully simple.

For the past 6+ years, I’ve had the privilege of working with visionary companies like Zscaler, Kayzen (a Berlin-based AdTech startup), and Nokia. Along the way, I’ve built large-scale data systems, real-time analytics pipelines, and machine learning solutions that not only solve problems but unlock possibilities.

What excites me most is the blend of engineering and storytelling, designing pipelines that whisper insights, models that predict tomorrow, and systems that empower people to make smarter choices.

Outside of work, I love mentoring aspiring engineers, contributing to the tech community, and chasing experiences that push me out of my comfort zone, from mentoring 200+ students, to skydiving over Prague at 15,000 feet, to diving deep into the blue waters of the Andamans.

I see every project as an adventure and every challenge as a chance to grow, and I bring that same spirit to every team I work with. 🚀
