I've been building SaaS since 2008 and built two with Go. Big spoiler, the technology you choose has a little impact in the early stage of a software business. There's some danger to over-engineer and use complex construct while you still does not even know if what you're building is desirable. Heck, you don't even know what you're building at first. I'm giving some example of common traps and pitfails technical founder tend to fail into when jumping into a startup venture for first times. And yes, times is plural, because it takes multiple attempt before learning lessons. If you enjoy the pod please consider sharing / talking about it.

My upcoming SaaS product at first wasn't suppose to be rolled out as a product, but was for my own usage. Turns out as I was using it and selling my online courses that it appears to me as being fairly usefull and could compete against existing course selling platform. The hic is that it wasn't built as a SaaS in mind, so I have to deploy one application per customer. It's completely multi-tenant. To help with automating the deployment of a new tenant, I wrote and orchestrator with agents to facilitate the deployment of a new application. I thought this part could be interesting to hear about as it's written in Go. Want to support the show?

In this episode I talk with John Arundel about cryptography in Go. John wrote a great book on the subject called Explore Go: Cryptography. Security is a growing concerns and you should up your game as a Go programmer. We're lucky to have such a solid crypt package in the standard library. I'd encourage you to get familiar with it if you haven't yet.

In 2021 Twilio sent a termination email on their Fax services. I was consulting as the CTO in a credit bureau that was in the start of an acquisition process with Equifax Canada. There was just no time to "waste" on changing provider and rewriting this part of the system to satisfy the new provider API. Would have been grand if the provider would have offered a shim that replicated Twilio's API and map that to their own API. Imagine how many companies needed to rewrite this part at the same time. Offering this as the provider that receives X thousands new customers would have been a superb engineering experience. So maybe we can apply this concept internally as well. When a team needs to introduce breaking changes, a good solution might be for them to provide a shim over the old API so no other teams need to do anything. This is obviously a tad dangerous and might introduce some technical debt. But as everything, it depends.

I believe we can do better regarding software engineer interviews and this entire process (also including onboarding). I think companies that will be mediocre at those two aspects will have a hard time with younger programmers, which I fully support.

Iterators are going to be useful to process large amount of data without having to load an entire slice or maps in memory but instead create iterators that can be used from a for item := range myIterators().

Things were very different when I started as a junior developer. This is a story of an out of the ordinary day where worked from ~9h am to 11am (the next day), the two of us that were in charge of everything at a small financial company. This one has nothing to do with Go, but I thought it was worth telling as a story. I'm soon to launch (pre-launch) my next course Build a Google Analytics in Go.

As we're building more and more of distributed systems I believe that one trait / culture successful team will require is discipline. Personal opinion, we tend to complicate our lives in the last decade compare to what things were before. But without an extra attention to some details, it will be a nightmare to maintain systems in the long run. As always, if you'd like to support the show the best way is to purchase my course.
