Erick Hernández Arias has delivered over 100 projects across 18+ years for clients in the Dominican Republic, Puerto Rico, and the United States.
Your business needs technology that actually works. I build it.
I provide web design and full-stack development services for businesses in the DR, Puerto Rico, and the United States. With over 18 years of experience and more than 100 projects delivered, I've helped managers and CEOs transform weak digital presences into websites that generate business, manual processes into intelligent systems, and disconnected tools into integrated ecosystems.
You don't need to juggle a designer, a developer, and an AI consultant separately.
I handle the full picture from a single point of contact.
How I work with you.
Every project starts with a conversation. I listen to what you need, analyze your business context, and propose a concrete solution — not a generic template.
The process has four clear phases:
- Discovery — I understand the problem, your target audience, and your business goals before writing a single line of code.
- Design — I create wireframes and high-fidelity prototypes in Figma to validate the user experience before development begins.
- Development — I build the product using the right technology for each project: Flask, React, Shopify, or whatever AI integration you need.
- Launch & support — I handle deployment, walk you through managing your content, and remain available for post-launch adjustments.
I work with businesses in Santo Domingo and across the country, as well as clients in Puerto Rico and the United States. Communication is always direct — no account managers, no middlemen.

Frequently asked questions.

How long does a landing page take?
A landing page is delivered in 7 business days. A full corporate website takes 2 to 3 weeks. Every project includes a review round before final delivery.
Do you work with clients outside of Santo Domingo?
Yes. I work with clients across the Dominican Republic, Puerto Rico, and the US — fully remote via WhatsApp, email, and video call.
How can AI benefit my business?
AI can automate document digitization, generate reports, answer customer inquiries, and analyze data. I integrate LLaMA 3, Gemini, and Groq API into business and educational systems, cutting manual work and improving operational efficiency.
How do I know what kind of website my business needs?
It depends on your main goal. If you want to capture leads or promote a specific service, a landing page is usually enough. If your business has multiple services, a team, or you need to rank for several keywords, a multi-page website is the right call. If you sell physical or digital products, you need an online store (Shopify or WooCommerce). The initial consultation is free and no-commitment — I'll tell you exactly what makes sense for your situation.
What's the difference between a freelancer and a web design agency?
With a freelancer you get direct communication with the person actually doing the work, lower costs with no agency markup, and more flexibility on scope and timelines. Agencies have larger teams but also higher overhead that gets passed on to you. For most small and mid-size businesses, a senior freelance developer with multidisciplinary experience offers a better value proposition. Read more articles →
