FAQ
Common Questions
How does pricing work?
No fixed packages. After a short call about what you need, I send a written scope with a fixed price or an hourly estimate, so you know the cost before any work starts.
You're in Manila. Will our hours overlap?
Yes. I keep early-evening hours in Manila that line up with US mornings, and my regular day covers most of the Australian workday and UK mornings. We pick a call time that suits you.
How do we get started?
Send an email or use the form below. I reply within 24 hours (Mon–Fri, Manila time), then we schedule a call to go over the project.
Which tools do you work with?
Shopify, WordPress and WooCommerce for sites and stores. Zapier, n8n and Make for automation, with Airtable and Google Sheets as data layers. Cin7 Core for inventory and pricing sync.
Do you offer support after launch?
Yes. I can stay on for fixes, small changes and monitoring of automations, either as needed or on a monthly arrangement.
What do you need from me?
Admin or collaborator access to the platforms involved, your brand assets and content, and one person who can answer questions and sign off on each milestone.
Special Thanks
The Spark Behind the Work
Nick Le, Director at SentryX. Read why
Sometimes the right leader changes everything.
"Before Nick, I was going through the motions. He gave me real ownership — Shopify builds, automation pipelines, critical releases — and never once questioned whether I could handle it. That environment made me want to go further. I started building tools on my own initiative, just because I finally felt like my work mattered. That's what a great leader does — not push you forward, but make you want to move yourself."
— Jonathan Tubay
