Full Stack Engineer. Backend by Obsession

I'm Chiemezuo (Chi-ei-may-zu-oh), or "Mezuo" (May-zu-oh) for short — a full-stack engineer who lives mostly on the backend (Python/Django, Node.js, Bun, and yes, occasionally Java when Spring Boot calls).

▎ 3+ years shipping production systems in FinTech and EdTech, two-time Google Summer of Code fellow on Wagtail CMS, and a firm believer that good code and a good joke should both land on the first try.

▎ If you need someone to build the thing, fix the thing, or explain — with minimal condescension — why the thing broke, that's me.

What I actually do

▎ Backend systems that don't fall over: Python/Django, Node.js, Bun, Java/Spring Boot, REST APIs, and the PostgreSQL/Redis/MongoDB that keeps them honest.

▎ I ship React/TypeScript frontends when the backend needs a face, wire up Docker and CI/CD so deploys aren't a personality test, and I've spent enough time in AWS, GCP, DigitalOcean, Heroku, and Railway to have opinions about all of them.

▎ Bonus skill: accessibility and testing (PyTest, Playwright, Jest, Axe-core). I'll notice if your app is unusable with a screen reader before your users have to tell you.

What to call me for

▎ Full-stack builds from zero to production. API design and architecture decisions that don't need a rewrite in six months. Performance and database work.

▎ I once halved page-load times by refusing to let an ORM make bad decisions unsupervised.

▎Accessibility audits, because "it works on my machine" isn't a compliance strategy.

▎And if you need someone who can talk to Django & Wagtail core maintainers, GSoC mentors, and a confused stakeholder in the same afternoon, I've had the practice.

What I'm currently up to

▎ Building internal fintech tooling where every number must reconcile, and the UX must make that obvious.

▎Contributing to Wagtail CMS (yes, the one powering this site), continuing accessibility and security work after two GSoC fellowships.

▎Tinkering with startup ideas. Some are promising. Some are just a domain name.

▎Procrastinating about starting YouTube videos and a podcast-shaped thing.

▎Learning The Rust Programming Language.

What I write about

▎ Backend architecture decisions and the tradeoffs nobody puts in the tutorial. Open source — what it's actually like contributing to a CMS used by Google, NASA, and the NHS. Accessibility, because it's the most underrated skill in the industry. And the occasional post-mortem on something I broke, because pretending everything always works is how you end up trusting me less, not more.
