About me

A teacher who builds websites

I am a Licensed Professional Teacher teaching senior high school STEM in Laguna. I started building websites to solve problems in my own classroom: lost papers, scattered files, students checking in when they weren't there. Those tools became Seedara, a product other teachers now buy.

Teaching made me good at what clients value most: listening carefully, explaining things simply, and making tools people can use without training. I use modern tools, including AI coding assistants, to build faster, and I personally test and stand behind everything I deliver.

FAQ

Common questions

Will I own my website?

Yes. The site, the code, the domain and the hosting are set up under your own accounts. You're never locked in to me.

Are there monthly fees?

Most small business sites I build run on free hosting (Cloudflare Pages, Netlify or Google). You usually only pay for your domain name each year. Ongoing maintenance is optional.

How much does a website cost?

It depends on what you need. A one-page site costs much less than a system with logins and payments. Tell me about your project and I'll send a written quote, usually within a day.

What if I don't like the design?

You see a preview before the full build, and revisions are included in every project. With the free redesign offer, you pay nothing if you don't like the preview.

Do you work with clients outside the Philippines?

Yes. I work remotely, reply in English, and can overlap with Australian, Asian, European and US evening hours. Payment by PayPal or Wise.

How do you work with a full-time teaching job?

I take a limited number of projects at a time and schedule them so every deadline in the quote is met. You'll always know where your project is.
