Things I got wrong.

Scaling from 15 to 89 people, I prioritized speed over fit. We had open positions and pressure to fill them. I lowered the bar on some hires because we "needed bodies." Then I waited too long to act when someone clearly wasn't working out.

Team morale suffered. High performers got frustrated covering for underperformers. By the time I acted, the damage was done — some of my best people had already mentally checked out.

I built a microservices architecture for a product with 100 users. So focused on "doing it right" and "building for scale" that I created complexity we didn't need — service mesh, event sourcing, CQRS, the whole enterprise playbook for a startup.

Development slowed to a crawl. Simple features took weeks. New developers took months to onboard. We spent more time maintaining infrastructure than building product.

For years I thought being a great engineer was enough. I built products and waited for people to discover them. I saw sales as manipulative, something for "business people." I was too proud to ask for what I wanted.

Good products died in obscurity. Colleagues who were worse engineers but better communicators advanced faster. I stayed in my comfort zone while the world moved on.

I wore 80-hour weeks like a badge of honor. Sleep was for the weak. I missed family events and ignored my health, convinced it was temporary. "Just until we ship this feature." The goalposts kept moving.

My health suffered. Relationships strained. My decision-making got worse the more tired I got, which created more problems, which required more hours.

As CTO, my job was to lead, not code. But I kept diving into PRs, rewriting things "the right way," becoming a bottleneck. I didn't trust my team to make decisions.

I became a single point of failure. My team stopped taking initiative because they knew I'd change it anyway. Exhausted from doing two jobs poorly instead of one well.

Every Hacker News post about new tech sent me down a rabbit hole. New database? Try it. New frontend framework? Rewrite everything. So focused on tools I forgot about outcomes.

Projects never finished because I was always starting over with "better" tech. Teams got frustrated learning new stacks every quarter. We accumulated more debt from migrations than from actual development.
