Alex Yang
Software Engineer
Intro
- I lead teams to architect and build maintainable, scalable, secure, and well-tested systems.
- I support and unblock team members and mentor junior developers.
- My chief skills are listening, asking questions, clarifying doubts and ambiguities, writing documentation for the future, and facilitating discussion.
- I’m a pretty nice colleague. 😌
I have sometimes been given titles like “tech lead” or “software architect”. But even in these roles I very much prefer flattening the hierarchy so everyone, even interns, gets to research, peer review, and make key decisions together. Of course, when things go wrong, it's my fault. 😁
Important: because of disability, I require 100% remote. No hybrid. Thanks for your understanding. 🙏🏼
Feel free to reach out on LinkedIn. I’m open to new opportunities, collaborations, and interesting projects. Full-time opportunities only though. I do not freelance (for now). But please, please, please provide some context on why you’re reaching out. Otherwise I think you're spam or a bot or a phisher. Thank you! 🙏🏼

- Sovereign infrastructure in the EU and Southeast Asia. Building k8s platforms using EU providers like Hetzner, LeafCloud, UpCloud.
- Global internet infrastructure: undersea cables, data centres, IXPs, OSI model, BGP, how data transforms to get memes from my laptop to your mobile, commercial agreements, etc. We built this. Crazy.
A little more about me
- My current favourite thing to do in my spare time is study Rethinking Statistics by Richard McElreath (with Jupyter Notebooks).
- I also unicycle. Do you want to unicycle? We should start a unicycling gang. Hit me up even if you don’t want me for jobs. It’d be hilarious if a whole bunch of us unicycle through the centre of Stockholm.
