Fer Martin

I make personal software with AI.

onflow.studio is where I build tools that work my way, then open them up so they can work yours. Every one of them started as something I needed, and was built feature by feature in a conversation with AI.

# story

Twenty years of software, and the teams that build it.

I've worked at Telefónica I+D, EMC and Citibank. I was CTO of PCCW Solutions in Hong Kong, leading more than 25 engineers, and most recently led engineering at ComplexChaos, an AI collaboration platform where several language models work together.

I founded Reboot Academy, a coding school that has taken more than 600 people into tech jobs, and led the building of Edukami, an AI training platform used by companies, universities and public institutions.

Along the way I've lived and worked in Spain, Japan, Hong Kong, Singapore and the USA. Years of teaching people to build are where the studio's idea comes from: the best tool is the one shaped around how you actually work.

# why

Software used to take a team. Now it takes a conversation.

Most software decides how you work: its tabs, its layout, its settings for someone else's problems. You adapt, because building your own used to cost a team and a year.

That cost is gone. A tool shaped around one way of working now takes days, so I build the ones I want, keep the ones worth keeping, and publish them for anyone who wants to fork one and make it theirs.

# how i work

  • 01

    Built in conversation

    Every product here was designed and built with AI, one feature at a time. The instructions and design docs the AI works from live next to the code.

  • 02

    Agents take the queue

    Issues marked ready go to coding agents, each in a worktree of its own. I answer their questions from one inbox and review what they hand over.

  • 03

    Used before it ships

    Each tool runs my own day first: my mail, my focus music, my usage limits. If it doesn't hold up there, it doesn't ship.

Follow along.

New tools, new features and how they're made. Shogun Flow is built and on its way to npm. Follow the studio on GitHub or find me on LinkedIn to hear when it opens up.
