I will build a custom gutenberg block or block theme


About this gig
Need a custom Gutenberg block your editors can configure without touching code or a full Block Theme built from scratch? I build modern WordPress the right way: no page-builder bloat, no fragile plugins.
20+ years as a full-stack engineer and former CTO. I build custom Gutenberg blocks and Block Themes using the Interactivity API and Block Bindings API modern Gutenberg most "WordPress developers" haven't touched. Recently shipped a fully block-based bilingual nonprofit theme: 13 custom blocks, 56+ reusable patterns, WCAG 2.1 AA (
What you get:
- Custom Gutenberg block(s) built from scratch (React not a plugin wrapper)
- Block Theme with theme.json, patterns, and editor-driven config
- Interactivity API for live, no-reload front-end behavior
- Block Bindings API so editors change content, not code
- Responsive + accessibility-aware, clean maintainable code
- Handoff docs so your team edits confidently
What I don't do: Elementor/Divi page-builder work or generic theme tweaks.
Send me your design and requirements I'll tell you straight up what's possible and scope it honestly, usually within a few hours.

FAQ
Do you use a page builder?
No — custom blocks and Block Themes only, so your site stays fast and editable without premium plugins.
What do you need from me to start?
Your design (Figma/PSD or reference sites), a list of blocks/sections, and staging access. I send a checklist at checkout.
Can you extend my existing theme?
Yes if it's a Block Theme. If it's a classic theme, I'll advise whether converting is worth it.
How many revisions are included?
Each package includes revisions (see package details); I aim to get it right the first time.
