Teresa (Katy) Castillo – Web Developer

I am a visual/web designer who specializes in creating accessible websites and branding solutions for creatives and small businesses.


For several years, I have been collaborating with my life partner, an award-winning front-end developer, on web development projects. We strive to create accessible websites that meet the WCAG 2.2 requirements.

Combined, we both have extensive knowledge of web design and development and have worked with multiple companies such as Crunchyroll, CultivateWP, and Anime Planet (see our full client list on our site). We've also helped several small businesses, fandom blogs, and creatives (such as podcasters, translators, and artists).

My partner specifically has worked with CultivateWP for three years to build out over +30 custom WordPress themes for food and lifestyle bloggers, including Food Dolls, Just A Taste, Nom Nom Paleo, and Well Plated.

Our combined skillset includes Web Design, WordPress, Branding, Accessibility, SEO, Javascript, HTML5, CSS3, PHP, Squarespace, WCAG (Web Content Accessibility Guidelines) 2.2, Gutenberg (WordPress Block Editor), and Social Media.

We can create accessibly beautiful and engaging websites that suit your specific needs, whether you require a one-page, multi-page, blog, or e-commerce website.

Our Services include:

• WordPress website design and development

Lonnie Mann - Gaytheist

Lonnie reached out to us to create a landing page for his new book, Gaytheist! They provided a wireframe. We used it to design and develop a single-page website with two different sections for blurbs and featured reviews, a beautiful slider to display the first chapter of the book, and a menu that highlights which section you are on the page.


To help support the site, I created a shop store using WooCommerce for Yatta-Tachi. All the branding, product designs, and customization were done by me. Featuring Yatta-Tachi's fox mascot, Hachi, throughout the site.

Yatta-Tachi Gift Guide Hub

Yatta-Tachi wanted to create a hub for the gift guides. Built using WordPress' blocks.


Yatta-Tachi is a Japanese pop culture website. I am the owner & Editor-in-chief of the site. My partner and I redesigned the site in 2020 to better reflect our branding and messaging. It is a deeply robust site with multiple templates and customizations.
