I build products with AI. Currently building Hapsay.
I'm Dorell James, a product engineer based in Cebu. Over a decade of shipping products, leading teams, and growing communities — now focused on building Hapsay, a 24/7 AI booking assistant.
Privileged to work and/or partner with these industry-leading companies and communities
Current Focus - Hapsay
A 24/7 AI booking assistant for sports complexes and wellness businesses. Automatically converts customer inquiries into confirmed reservations across Messenger, Instagram, WhatsApp, Viber, Telegram, and your website. SMS and voice coming soon.
Every unanswered DM is a booking you'll never get back. Hapsay responds instantly to customer inquiries, checks availability, calculates dynamic pricing, and confirms reservations — all in one conversation, 24/7.
What I Do - Build products. Use AI seriously. Share what I learn.
I build products that solve real problems, use AI as a genuine collaborator in that process, and share what I learn with the community along the way.
- Build Products. I ship real things. Right now that means Hapsay — a 24/7 AI booking assistant that converts customer inquiries into confirmed reservations across Messenger, Instagram, WhatsApp, Viber, Telegram, and your website.
- Use AI Responsibly. I use AI to migrate legacy systems, prototype faster, and handle repetitive patterns. But AI proposes, I verify. That approach helped me rewrite an entire payment system without breaking production.
- Share What I Learn. I speak at events like GDG DevFest, write about building with AI, and help grow the Cebu dev community through JS Cebu and React Cebu. Open to mentorship conversations and speaking engagements.
Portfolio - Work that reflects how I build
I've worked across products, platforms, and communities. Here are a few that represent how I think about building — from experiments and open-source to long-term platforms.

About - The longer story (short version)
I started like many devs here: small projects, freelance gigs, and that one unforgettable job where I was just asked to make "three equal columns" on a website. I thought that was it — ship, get paid, move on.
Over the last decade, that turned into leading teams as a CTO, building platforms like Stackshift, organizing dev communities in Cebu, and using AI to rewrite an entire legacy payment system without breaking production.
Now I'm channeling all of that into Hapsay — an AI-powered booking assistant. I build in public, I use AI seriously, and I write about what I learn along the way.
