How Senior Software Engineers Balance Speed and Quality (Scale-Up Lessons)

The difference between a junior and a senior engineer isn't coding speed, it's knowing when to say "no."

"The best code you can write is the code you don't write." In this episode, I sit down with Alessandro Mautone (Senior Software Engineer at Aquablu, ex-WeTransfer) to discuss the reality of engineering at a scale-up: how do you maintain technical excellence when the business demands speed?

We break down why delivering features "fast" pays your salary, but how to negotiate deadlines so you don't drown in technical debt later. If you want to move from writing code to owning product decisions, this conversation is for you.

In this episode, we cover:

- How to push back on features and negotiate deadlines without upsetting stakeholders

- Why chasing "perfect code" can hurt a company in growth mode

- The Generalist vs. Specialist career path: Which one is right for you?

- The potential pitfalls of using AI for unit tests without proper oversight
