FAQ

Everything You Need to Know
Before Hiring Me

Before reaching out to a developer, everyone has the same questions. Here are my straightforward answers.

Do you have real experience with Shopify Plus?+
Yes. I have worked directly with Shopify Plus on live production projects like Curveez, where I led the entire ecosystem: dynamic sections, Sections API, advanced Liquid, custom apps, and CR optimization. I also develop in Shopify Hydrogen for high-performance headless architectures.
Can you handle the entire project alone, or do I need a team?+
With 14 years of experience across frontend, backend, databases, and e-commerce, I manage the full lifecycle. For small and medium-sized projects, I deliver solo. For larger projects, I have a network of collaborators and can coordinate the technical team based on the scope.
How long does a project take to deliver?+
It depends on the scope. An optimized landing page takes 3-5 days. A fully configured Shopify store takes 1-3 weeks. A full-stack web application takes 4-12 weeks. AI integration into my workflow reduces delivery times by up to 40% compared to traditional development.
Do you work only with Colombia or also internationally?+
I work 100% remotely with clients from Colombia, the United States, Mexico, Spain, and the rest of Latin America. I have the technical proficiency in English required to read documentation and communicate seamlessly with international teams.
Do you handle technical SEO for my website?+
Yes. Technical SEO is a core part of my work. This includes audits, Core Web Vitals, page speed, URL structure, Schema.org structured data, and fixing crawl errors that directly impact organic rankings.
Can you integrate artificial intelligence into my business?+
It is one of my latest specialties. I integrate OpenAI and Claude (Anthropic) APIs, handle automation with n8n, deploy AI agents, build automated content generation, implement RAG over your documents, and design smart workflows that eliminate manual tasks. I have been a pioneer in AI-applied development since 2022.
What sets Mario apart from other freelance developers?+
14 years of real production experience, deep specialization in high-volume e-commerce, leveraging AI to cut delivery times without compromising quality, and a strong focus on business results. I don't just deliver code — I deliver conversions, speed, and sales.
What happens after you finish the project? Is there support?+
All projects include a warranty period and post-launch bug fixing. Ongoing long-term support is negotiated based on the client's needs. I believe in building long-term relationships rather than doing one-off deliveries and vanishing.
How much do your services cost?+
Pricing varies based on scope, technology stack, and required delivery timeline. I offer hourly rates, fixed-price project quotes, and monthly retainers. The best way to get an accurate quote is to message me on WhatsApp and tell me about your project. The initial consultation is completely free.
