Hi I'm Aravind Kumar 📍 Belfast, Northern Ireland, UK — Engineering Manager by day and Batman during dark! Intrigued by Open-Source and building things that matter.
I'm not a perfectionist. Excellence is my pursuit!
With over 15 years in software, I now lead cross-functional engineering teams at OptumUK, driving the evolution of the Cohort Builder platform — a large-scale healthcare data extraction and analytics system supporting national programmes. I take pride in building high-performing teams, mentoring engineers, and enabling a culture of continuous learning.
My core stack is Python & AWS, and I actively work with React.js, GoLang, and modern data-engineering tooling (Airflow, CI/CD, GitHub Actions). In earlier years I worked extensively with PHP, SugarCRM, and a wide range of web frameworks.
I love to learn new things every day. What I believe in is
We live in a world where robots can drive a car, so we shouldn't just write code, we should write elegant code.
Also, I'm a big fan of rain, snow, and mountains — Green places basically. It sums up that I'm a nature-loving person.
Wait.. wait.. you should really know this. I'm a big ARSENAL
Fan!

“We live in a world where robots can drive a car, so we shouldn't just write code, we should write elegant code.”
“Excellence is not a skill. It is an attitude.”
“First, solve the problem. Then, write the code.”
“Any fool can write code that a computer can understand. Good programmers write code that humans can understand.”
“Code is like humor. When you have to explain it, it's bad.”
“The best way to predict the future is to invent it.”
“Talk is cheap. Show me the code.”
“Simplicity is the soul of efficiency.”
