Frequently Asked Questions

Clear answers to common questions

Everything you need to know about how I work, timelines, tech stack, and scope.

01 What kind of solutions do you build and what tech stack do you use?
I build high-performance landing pages and websites with Astro (and React islands for targeted interactivity). For complex web platforms, business portals, and custom dashboards I use Angular. For cross-platform mobile apps (iOS & Android) I use Angular with Ionic.
02 How long does a project take to complete?
It depends on the scope. A landing page or commercial website typically takes 2 to 4 weeks. A custom web platform or mobile app typically takes 6 to 12 weeks, with continuous progress updates and staged milestones.
03 What is the advantage of a custom solution over templates or page builders?
A custom solution loads in milliseconds, does not rely on fragile third-party plugins that break, ensures top-tier security, maps precisely to your business workflows, and gives you 100% code ownership without recurring locked-in builder fees.
04 How does the work process look and what does the quote include?
The process follows 4 clear phases: (1) Business problem understanding, (2) UX and architecture design, (3) Development with quality and accessibility testing, and (4) Launch and handover with support. Quotes include fixed scope, source code, and handover guidance.
05 Do you work with clients outside Colombia?
Yes. I have experience building projects for businesses in both Colombia and the United States, with fluent communication in Spanish and English and remote agile collaboration.
