Hey 👋

I’m Athul Cyriac Ajay, a Site Reliability Engineer from Kerala, India. I love working with infrastructure, writing code, and solving interesting problems.

I currently work at Ultrahuman(12/2025 - ), where I’m part of the team building and maintaining the infrastructure behind their metabolic health platform and the ring.

Before this, I was an SRE at KnowBe4(01/2024 - 12/2025) in Release Engineering, where I worked on distributed systems, managed GitLab infrastructure, and helped teams ship code faster and more reliably.

Prior to that, I spent a couple of years at Frappe(07/2022 - 12/2023) as a Platform Engineer, working on cloud infrastructure and helping make ERPNext deployments smoother for their customers.

Along the way, I got to work on a few interesting things—like implementing GitLab Geo across regions and building internal systems to track AI adoption metrics at KnowBe4, Managed Hosting and functional automations at Frappe.

I enjoy building tools and contributing to open source. Some projects that people seem to find useful include Waka-Readme (a GitHub Action that shows coding stats on your profile with 1,700+ stars), Archie (the minimal Hugo theme that powers this site with 1,200+ stars), and Shelby (a fast shell prompt written in Go with 180+ stars). Check out more of my Projects or my Resume if you’re curious about the technical details.

I primarily write Python and Go, work a lot with AWS and Terraform, and enjoy building things with FastAPI, and Vue. Most of my day involves Docker containers, Kubernetes, CI/CD and various monitoring tools.

When I’m not coding, I (used to) have a thing for building mechanical keyboards - especially split keyboards like the CRKBD and KLOR. There’s something satisfying about soldering switches and getting that perfect typing feel. These days with Claude, I’m building Android apps and other personal pet websites and automations. I love exploring Kerala on weekend bike/car trips, watching movies, reading books and sometimes just sleeping in. I also write about my projects and experiences on my blog. It’s mostly year end reviews on my blog these days but I try to write more.

I graduated with a B.Tech in Computer Science from College of Engineering Kidangoor under APJ Abdul Kalam Technological University in 2022, where I was fortunate to receive the Best Outgoing Student Award. I’ve been writing code since 2018, starting with Python after high school. Before that, it was mostly C++ for school projects.

Always happy to chat about tech, keyboards, or anything interesting. You can find me on Twitter @athulcajay, GitHub athul, Telegram @a2hu1, or email athul8720[@]gmail[.]com.
