From cloud architect to startup founder: my story

Before: solid on paper, still searching

On paper, things looked great. A decade in tech, working closely with founders, helping them scale from their first customer all the way to Series C and beyond. I loved being part of that. But there was a quiet question that kept surfacing, especially during late-night freelance projects or packed Tokyo subway rides:

“When will I build something that’s mine?”

One evening, crammed into a train car and sketching out yet another internal tool for someone else, it hit me. I had spent years helping build other people’s ideas but I had never taken one of my own from sketch to something a real person loved. I knew I didn’t want to look back and regret never trying. So I started looking for a reset button.

That’s how I found Le Wagon Tokyo.

During: 9 weeks that rewired my thinking

My goal wasn’t flashy. I wasn’t there to launch a startup right away. I wanted to break old patterns, rebuild my confidence as a builder, and prove to myself that I could learn fast without a safety net.

Bootcamp life delivered.

Each day had its own rhythm: pair-programming in the morning, live-coding after lunch, and evening talks that somehow always sparked new ideas. My classmates came from all over: a designer, a teacher, a consultant, and working with them made me better at explaining technical concepts in plain language. That alone reshaped how I think about users.

We built small things. We broke them. We learned.

We shipped something every day. And in doing that, I learned to chase progress, not perfection.

I didn’t leave Le Wagon Tokyo with a polished startup idea. But I did leave knowing I was ready to tackle one.

After: building Brightenly, a friendly CRM for freelancers

A couple of years later, while freelancing full-time, I started noticing a pattern. Scattered emails. Verbal agreements with no paper trail. Invoices that took forever to get paid. I wasn’t alone: every freelancer friend I talked to had the same headaches.

So I pulled out those bootcamp lessons  – build fast, talk to users, iterate small – and got to work.

That work turned into Brightenly: tools built for freelancers who want to spend more time working and less time chasing payments.

A unified inbox that keeps all messages in one place and tags the ones that should be billable.

Instant contract templates that turn a “yes” into a signed agreement before momentum fades.

One-click invoices connected to Stripe, so payments come in days, not weeks.

Auto task capture that pulls action items straight from emails and turns them into to-dos.

Brightenly’s now in private beta with a small group of users. It’s familiar territory: ship something small, gather feedback, refine.

For future bootcampers dreaming of launching something

If you’re thinking about doing a coding bootcamp in Tokyo or wondering what happens after, here’s what I’d share.

First, come with a question. Mine was: What does it really take to ship my own product? That question shaped how I approached every group project, every bug, every late-night struggle with new tech.

Second, don’t treat it like a performance. I did, at first. I wanted to “get everything right.” But bootcamp isn’t a test, it’s a lab. A place to experiment, mess up, and grow.

Third, lean into the community. I got feedback, encouragement, even beta testers, all from alumni Slack channels. Those connections are still paying off today.

And finally, share your work early. You don’t need to be ready. You just need to be visible. The feedback you get from even a half-finished project is 10x more valuable than perfecting something in isolation.

Le Wagon gave me the space to turn curiosity into capability.

If you’re wondering what might be on the other side of nine intense weeks, I hope my story nudges you a little closer to finding out.

If you’re thinking about bootcamp life, freelancing, or starting something of your own, feel free to reach out. Always happy to trade notes.
