Where to start?

Every project is quoted according to its scope: I send you a proposal with timeline and cost before we start.

Good to know: proposals cover design, development and launch. Hosting, domain and SSL certificate are paid by the client, and I help you set them up. If you would rather have me handle hosting and maintenance, ask me and we'll tailor it to you.

// questions

Frequently asked questions

What almost everyone asks before getting started.

How much does it cost and how is it quoted?

Every project is quoted according to its scope. We talk first, I understand what you need, and I send you a proposal with clear scope, timeline and cost before writing a single line of code.

How long does a project take?

It depends on its size: a simple site is nothing like a system with users, permissions and reports. In the proposal I give you dates by stage, with frequent progress updates so you can review as we go.

What do I need to get started?

Tell me how your process works today: an Excel file, paper forms, emails… Examples help. With that I understand the problem, who will use it and what the system must solve.

Can you work with sensitive information, such as member data?

Yes. My systems include role-based access, audit logs and validations, and I consider personal data protection from the design stage. If your organization has its own security policies, we review them at the start.

Who owns the domain and the system?

The domain should be registered in your name, because it is your address on the internet. The terms about the code and the use of the system are written into the proposal, so both of us are clear about what is delivered.

What happens after delivery?

Delivery includes launch, training and support after go-live. If you need improvements or ongoing maintenance, we talk it through based on what your team needs.

Can you improve a system I already have?

Yes. I can review what already works, fix it, add features or migrate it, whether it is a database, an intranet or a web application.

Do you work with clients in other cities or countries?

Yes, I work remotely from Cali, Colombia (UTC-5 time zone). You can write to me in Spanish or English.
