Hi! I’m Humza - Hum like in hummer and za as in plaza - a Lahori living in London by way of Saarbrücken.
I’ve been building software professionally since 2011. Most of this work has involved backend web development, DevOps, statistical model training, and data pipelines.
I’m passionate about disentangling complexity in technical projects and improving organisational culture.
Reach me at humzashah at gmail dot com if you’d like to discuss something that I could help with or if you’d like to invite me for a talk.
Read on for details of my work experience, conference talks, and qualifications.
