Gabriel J. CantresSoftware Engineer & Odoo Specialist
Fixed-price websites, custom web apps and integrations, and Odoo ERP done right. One bilingual engineer in Puerto Rico, from the first call to launch and beyond.
A professional site at a fixed price, live in about 2 to 4 weeks.
From $595
Web apps, customer portals, booking systems, integrations, and automation that takes busywork off your team.
Implementation, custom modules, migrations, integrations, training and support, from a certified engineer who also writes the code.
Six working rules you can hold me to.
Fixed prices for websites, written quotes for everything else. No surprises.
You pay for the work, not a monthly fee. Hosting runs on free plans when possible.
On final payment, the code, the site and the domain are yours, in your name.
Contact forms send messages straight to you. I work only with the access you give me, and I don't keep copies of your data after the job.
Every change goes to a preview or a staging copy first.
I use AI tools to move faster and keep costs down, and I review every line before it ships.
Four steps, in plain terms, so you always know what happens next.
We start with a short call about how your business runs today and what's getting in the way. You talk, I ask questions.
You get: A short summary of what I heard.
I turn the call into a written plan: what gets built, in what order, how long it takes, and what it costs.
You get: A written plan with a fixed price or an estimate.
I work in small steps and show you working software along the way, so you can steer before anything is finished.
You get: A preview link you can click through as it grows.
Go-live with your data migrated and your team trained. After launch I stay on for fixes and the next round of improvements.
You get: A handover with logins, documentation and ownership. After that, hourly support only when you need it.
Client case studies are on the way. Until then, these labeled examples show the kind of problem I solve and how I'd approach it.
I'm Gabriel J. Cantres, a software engineer and Odoo-certified specialist in Hatillo, Puerto Rico. G-Computing is my independent practice, so you work with me directly: no hand-offs between a salesperson, a project manager, and a developer.
I work best with owners and operations managers who know their business and need someone to turn that knowledge into systems that run smoothly. I explain things in plain language, put decisions in writing, and build in small steps so you see progress early.
Yes. I'm based in Hatillo and work with clients across Puerto Rico and remotely. Calls and previews work from anywhere.
No. Websites have a fixed price and everything else is a written quote. After launch you pay by the hour only when you need something. There are no subscriptions or retainers.
You do. On final payment, the site, the code and the domain are yours, in your name.
50% when you approve the proposal and 50% at launch.
No. Prices don't include IVU where applicable.
Yes. I can improve or extend what you already have, or tell you honestly if starting fresh is the better choice. Small jobs are billed by the hour and larger ones get a written quote.
Send a few lines about your business and what you need. I'll reply by email to set up a call.
