Why talk to me
I've been building websites since around 2011, and WordPress has been a big part of that since 2013. I've been working remotely since 2015.
Most of my work is on real production sites that have to stay fast and keep working for years. I own the whole thing when I can: the theme, the plugins, the caching, the deploys, the migrations. Not just the ticket in front of me.
WordPress is a big strength, but it's not the whole story. I also build custom software and web applications around business requirements, and work with Astro, Next.js and React when a project calls for them. I care about practical solutions, performance and maintainability.

What I've worked on
-
Piktochart
About a year, sole WordPress developer
Owned piktochart.com, the highest-traffic site I've worked on. A Tailwind theme built on Automattic's
Read the Piktochart case study →_s, 60+ custom ACF Gutenberg blocks, a Git-based theme workflow on Kinsta, and migration work around Cloudflare and Kinsta. -
PlasticBank
About five years
Revamped the WordPress theme and did a lot of caching and performance work. I also moved the team from FTP uploads to Git-based deployment, which made shipping a lot less scary.

Povilo
2015 to 2023

Astro sites from Figma
Modern frontend
Turned Figma designs into Astro sites for zenti.com, sevenfigurecreators.com, bn2health.com.au and ebasgroup.com.au. Also built Supersite with Astro and CloudCannon CMS.

How I work
I'm a bit of a lazy developer, in the good sense. If I'm doing something twice, I'd rather turn it into a function, a component or a script. I prefer simple systems over clever ones, and I don't add abstraction just to look smart.
AI is a big part of how I work now. I use it for research, debugging and the repetitive parts. But I still read the code, understand it, and make the final call. I want to know what I'm shipping.
Use AI, but don't outsource your brain.
Outside the day job
I've given community talks on WP-CLI at a WordPress meetup in Malang, and on Full Site Editing at WordCamp Campus Connect at Universitas Ciputra, Surabaya.
I type on split keyboards, switch between macOS and Linux more than I should, and keep my side projects in a folder called FukaiMori, which means "deep forest." Big, strong, a little mysterious. That's where this site's trees come from.
