How we'll work
One person from the first call to launch day, so nothing gets lost in a handoff.
-
Step 1: Discover
A short call to understand the goal, the users and the constraints.
-
Step 2: Plan
A written scope with milestones, so we agree on what ships and when.
-
Step 3: Build
Frequent demos on a live URL. You see progress, not status reports.
-
Step 4: Launch
Deploy, measure and hand over. I stay around for what comes next.
Questions
Anything else? Ask me directly.
How much does a project cost?
It depends on scope. After our first call you get a written estimate with milestones, so you know the cost before any work starts.
How long does it take?
The plan sets a date for each milestone. Something usable goes live early, so you can try it with real users while the rest gets built.
Can you work with my existing team?
Yes. I can join your team and your repo, or own a product end to end and hand it over with documentation.
What time zone are you in?
Yucatán, Mexico (GMT-6). That overlaps with most of the US workday and all of Latin America.
What do you need from me to get started?
A short description of the idea, who it's for and any deadline. Links, screenshots or an existing codebase help, but they aren't required.
Can you help after launch?
Yes. I can stay on for fixes, new features and monitoring, or hand everything over to your team.
Have a project in mind?
Tell me what you're building. I'll reply with questions, a rough plan and next steps.
