Why work with me
- 01
On your hours
The Dominican Republic is on UTC−4 all year: the same time as New York from March to November and one hour ahead in winter. Calls happen live, with no overnight handoffs.
- 02
Banking and retail discipline
I’ve built internal APIs for a bank, integrated a payment gateway, and connected real-time orders and invoicing with SAP and the tax authority for one of the largest retail groups in the DR.
- 03
Fixed price, weekly deliveries
Scope, timeline and price in a written proposal before we start. You see progress every week and pay against deliveries.
- 04
Direct, no agency layers
You talk to the person who writes the code, in English or Spanish. Spanish-speaking teams and Latino-owned businesses get a native speaker.
- 05
The code is yours
When we finish, the code is yours. With the maintenance plan I stay on to keep it updated and running.
- 06
Real products in production
An education ERP, a distributor catalog with 364 products online and a multi-tenant clinic SaaS, all built end to end.

How we can work
Fixed-price project
Websites from US$ 250, online stores from US$ 450 and custom systems from US$ 850. The final price depends on scope and goes in the proposal.
Ongoing maintenance
From US$ 50 a month: security updates, SEO follow-up, checks that everything works, and content changes, so your site or system keeps working after launch.
Maintenance: more than swapping a photo
After launch I stay in charge. Every month I make sure everything stays secure, fast and working, and I tell you what happened.
- 01
SEO follow-up
I check in Google Search Console which searches bring you visits and which pages rise or drop, and fix what holds your rankings back.
- 02
Reports when you need them
If you want to know how your site is doing, I put together a clear summary: visits, Google searches and the work that was done.
- 03
Security updates
Libraries and dependencies kept up to date, and the HTTPS certificate and domain watched so nothing expires or is left exposed.
- 04
Everything working
I check that it’s online, loads fast on a phone and that the form, WhatsApp and every feature keep responding.
- 05
Content changes
Text, photos, prices and products: you send them by WhatsApp or email and I publish them, without you learning any tool.
- 06
Improvements and priority support
Adjustments and new sections when your business needs them, and a priority response if something breaks.
