Hanif Carroll
Forward Deployed Engineer
I learn how an organization works, figure out where software could help, and build it with the people who’ll use it.
Open to fully remote roles and direct contracts.
“Hanif helped me build and optimize features at Genrupt.com and was essential at getting the app ready for scaling. He is really organized and great at finding ways to make things more efficient. He is also a pleasure to work with!”

Feedback
“I hired Hanif for a project that included building a web as well as mobile app for spanish teachers and students. We made good progress on the project and published the app on App Store as well as Play Store. Its very enjoyable working with him and he was very responsive during the whole time. He also brought a lot of valuable input as well as ideas to the application. I recommend working with him.”
“He’s reliable, communicates great, and has a sharp technical mind. Whether handling complex builds, troubleshooting under pressure, or adapting to shifting priorities, he was dependable every step of the way.”
“He suggested design-to-engineering hand-off improvements to make our workflow more efficient, asked insightful follow-up questions during design reviews, and brought my Figma designs to life so we could deliver value to our users.”

About
Hey, I’m Hanif. I’m a forward deployed engineer based in Buenos Aires. I got into programming after Mr. Robot inspired me to learn how to code. I now have 9+ years of experience. The part of the work I enjoy most is the conversations: learning how people actually work and figuring out together what’s worth building.
After working at 8base, Capgemini, and LeagueApps, I now run HC Studio, where I work with founders and product teams to turn ambiguous ideas into useful, reliable software.
For the past three years, I’ve used coding agents to build software and complete workflows across websites and apps. My experience includes Cursor, Claude Code, Codex, and Pi. I’ve written about how I work and using agent-generated diagrams to review Casamo’s workflow.
I’m interested in how organizations work and how technology can fit around people. Right now I’m reading Thinking in Systems.
Outside of work, I like to lift weights, experiment with AI, and have merienda in cozy coffee shops.

Using diagrams to help AI agents find wasted work
I had an agent draw Casamo's report workflow, then used the drawings to decide where to look for wasted work in the code.
