I turn ideas into software.
I'm Carlo, an independent software developer. I build web apps and the systems behind them, for people who need something that fits the way they work.
About me
I'm Carlo Toledo, a freelance software developer. CTLabs (ctoledolabs) is the name I work under.
I build web applications and the systems behind them, including databases and APIs. Security is part of how I build from the start, not something added at the end.
I've launched products of my own and contributed to ones built by a team, so I'm comfortable working independently or alongside others.
Things I like working on
- Web apps
- Databases and backend work
- Security
- Small tools that save people time
Experience and skills
- Web apps
- Building and launching full web apps
- Layouts that work on a phone
- Backend and data
- Databases and APIs
- User accounts and permissions
- Security
- Keeping user data safe
- Thinking about how a feature could be abused
- How I work
- Independent and team projects
- Explaining things without jargon
