Start with a real need
I research what people are trying to accomplish before deciding what to build.
Independent developer · Chile
Useful web tools, built with clarity and purpose.
I’m Antonio Cortés, an independent developer creating practical tools that help people make everyday decisions with less friction.
About
Small tools can solve meaningful problems.
I work independently from Chile, researching and building focused web products for English-speaking markets. My goal is simple: turn confusing everyday tasks into clear, useful experiences.
I am currently developing a repeatable process for identifying underserved informational needs, validating demand, and publishing high-quality calculators and guides.
Current project
Moving Plan Tools
Free, straightforward calculators and planning guides for people preparing a move in the United States, Canada, the United Kingdom, and Australia.
How I work
Research first. Build carefully.
Make it genuinely useful
Every project should offer a clear result, not add more noise or unnecessary complexity.
Improve responsibly
I use feedback and aggregate demand signals to refine tools while respecting user privacy.
Transparent data use
Google Ads API use
I use the Google Ads API only for internal, read-only keyword research. Historical keyword metrics help me understand whether people are actively looking for a useful tool in a particular country before I decide to build it.
- No management of client accounts
- No creation or modification of advertising campaigns
- No resale or external distribution of Google Ads data
- No API access offered to outside users
