freelance project for a while! Hope to go back to it full time
If you have any routine maintenance like upgrading packages, adding widget tests, refactoring or general code quality, HMU! I can make a big difference quickly.

I'm currently developing software outside the software industry.
No Scrum. No JIRA. No meetings. No sprints. No microservices. No Clean Architecture. No DDD, TDD or other acronyms. I just build the software.

Smart people often write the worst code because they're more comfortable with complexity and have larger working memory. I've encountered this so many times in my career

This drives me nuts. I've worked on software for over 20 years and I've never had to write any algorithm more complicated than a bubble sort. It's simply not what developers do and if I found someone in my team writing an algorithm, I'd ask them why they're reinventing the wheel

Mobile app Dev is really a suckers game

I always start my projects with UI first. I fake the services and get it working. What the backend requires becomes obvious so I build it. Then, I connect the dots by adding services to actually make the API calls. Is that how you do it?

Pull requests are not the problem. The problem is how most teams manage pull requests. There is basically no substitute for feature branches unless your team is willing to work in a synchronous way.

Dependency injection gets abused too much in
#dotnet
. It's there to allow you to inject some concrete instances into classes that might have a few different interface implementations
Instead, it's used to configure everything from validation, mapping, to options

🚫 Avoid extra layering in apps upfront
Clean Architecture adds complexity and requires mapping 🔄. This affects performance and maintainability 📉
⌛ Extra layers = longer development, testing & debugging 🔧, plus a steeper learning curve 🎓 that can slow your team down

#Microservices
are inevitable at some large orgs. They get to a point where they can't add functionality to their monolith so every new piece of functionality is a microservice.
The problem is that adding services becomes so reflexive that they add services just to do things

You'd be amazed at how better your code is when you reserve abstractions for when they're needed.
Don't try to preempt the complexity. You'll just end up piling complexity on top of complexity.
My antidote to premature abstractions?
Abstracting with hindsight rather than foresight.

SOLID treats every component in your app like an independent reusable component. It forces you to treat each element with an extreme level of abstraction and decoupling.
Just remember, you’re building an app, not thousands of independent libraries. You don’t need to go that far

Another reason why I can't stand the modern approach to software development. Most companies block developers from directly reading customer support correspondence.
Why?
It's not the developer's job. That's the PO's job
The best founders I know — no matter their company’s scale — thrive on doing customer support directly. There’s literally no better way to understand the pulse of your customer base, what features to build next, or where systems are breaking down. It’s always upside.
