I'm Jean, an AI engineer in Pampanga, Philippines. I ship production systems, not demos: an AI search cut from 50s to 12s, sign-up onboarding time cut by 50%. You work directly with me at a fixed price, and most automations go live in 1–3 weeks.

No. I design websites and interfaces inside an existing brand. Send your logo, colors, fonts and any guidelines, and I'll build the web side of the system from there.
Starting prices are listed above. After a 30-minute call you get a fixed quote in writing within 2 working days, with the scope, timeline and milestones, so the number doesn't move unless the scope does. You pay 50% to start and 50% on delivery, and larger builds are split by milestone. Two rounds of revisions are included.
A landing page usually takes 1–2 weeks. Larger sites and web apps take 3–8 weeks. Most automations are live within 1–3 weeks.
