Hello, I'm Arjun. I'm an software engineer at ADP interested in building reliable backend infrastructure, scalable APIs, and secure software systems.
About me
I am a Software Engineer at ADP with a background in Computer Science and Data Science. I'm drawn to the intersection of mathematics and software engineering, with a particular interest in system design and building reliable, scalable backend infrastructure. My favorite part of engineering is architecting a solution from the ground up — thinking through the tradeoffs, designing for scale, and watching a well-structured system come to life. My core stack is Python, Go, Node.js, React.js, PostgreSQL, and AWS.
When I am not coding, I enjoy homelabbing, studying photography, watching movies, and playing pickleball.
