Hi all, I'm Marko, a software engineer living in Germany. I work as a Golang web developer and run a development company. I'm happy to help people who want to 🔸start programming 🔸get started with Golang 🔸transition from being developers to freelancers or creating their own dev companies

Centralized logs and metrics for docker containers: dev.to/krstak/docks...

If you are coming from OOP or procedural languages, the book that will blow your mind is The Little Schemer (Daniel Friedman) It's a must read.

An old article, but still very relevant for testing software. I often see developers making this mistake. If you’re wondering whether you should write a test for each function or method, this is a must-read. blog.cleancoder.com/uncle-bob/20...

When learning programming, start with the basics. Avoid frameworks. Focus on understanding core programming concepts. The choice of language isn’t that important.

Plan to learn #golang? It's a very powerful language and easy to learn. I highly recommend it. dev.to/krstak/why-g...

If you want to learn programming and get into software engineering, it's important to not give up. It’s not too hard, but there’s a lot to learn, and it takes time. If, after six months, you feel like you know nothing and everything feels jumbled in your head, don’t worry – that’s normal

Since my last post, I’ve added basic log analytics. If you’re using plain Docker in production, check it out → dockstats.com Free while in beta. Feedback welcome 🙏

I just launched a SaaS for developers who run their infrastructure on plain Docker containers. It helps you collect and view all your logs in one place. Features are still coming. I would appreciate any feedback. 🙏 #buildinpublic dockstats.com

I’ve never understood why tech companies use puzzle tasks (like leetcode) in interviews and base hiring decisions on them. Especially for the seniors. Sure, it's important to know the basics but a software engineer’s day-to-day job is much broader, and solving puzzles is almost never part of it.

I have used many programming languages in my career, but for the last 8+ years, I have stuck with Golang. I like its simplicity and explicitness.

Learn the following languages if you want to see: Java -> what OOP looks like Clojure -> what a functional language looks like Golang -> what a procedural language looks like JavaScript -> what a language made in 10 days looks like

How do I find new clients? By treating my existing clients with the utmost care.

Is it time for a bigger code refactoring? If you can't explain to your non-technical client, in plain English, why it's necessary, then it’s probably not the right time yet. (Ideally, we should never end up in this situation, as refactoring should be an ongoing process done in small steps.)

Never try to overcomplicate things in software engineering, since the complexity can ruin your software. Simplicity is a skill that needs to be trained.

Micromanaging developers might have a negative impact on the business. You should never do this. If you think they are not good enough, hire someone else.

I've used k8s and microservices for years while working for other companies. In my own company, I simply use docker and a monolithic service. It works just great.

Don't be religious about your tech-stack. It can hurt you and your business.

You don’t have to make other people wrong in order to be right

Who knew about this account? I didn't! #buildinpublic

If you build a business, don't fall into the trap of learning the latest programming language and tech just because it's cool. There are plenty of examples of how people failed because they wanted to pick the shiniest new technology for their products. Just use what you already know.

It doesn't matter what programming language you choose if it can get you to the market as soon as possible.

If you are developer, don't look for other developers to partner up.

k8s is a great tool, but only if you need it. The microservices approach is also great, but only if you need it. For my clients, I use simple docker composer and some basic shell scripts to deploy monolithic applications. That's all I need. Keep it simple, don't overcomplicate.

Run away from these people as fast as you can. They are ready to blame you and to make your life miserable even if it's their mistake

Last week I posted that we were migrating over to Hetzner from AWS How did that go? Amazing well #buildinpublic 🥳 We halved our costs while upgrading all servers to 3-4x their prev sizes We had resp time spikes that weren't sitting well with B2B customers during US stock market open hours, now:

If you want to dive into freelancing, listen what @rjmccollam.com has to say. Very valuable source of information.

Clients mostly don’t care about the technology you use. They care about results and how to make money. When it comes to building websites, WordPress is still No1.

I never underestimate the importance of developers' soft skills. A developer with great technical skills and poor personal/soft skills can harm your company. Both skills are equally important.

I professionally do programming every day. In my free time, I do it as a hobby, for free, because I love it. Some people don’t understand that.

People start valuing simplicity only when they are oncall and when their phone rings at 3AM

I don't use k8s for my clients. All these apps are internal business software apps. I simply use docker compose. Does anyone else use docker on production?

When I built my first SaaS, I thought: 'Let’s build it first, and the clients will come.' And indeed, I built it. But they never came. Building a business without marketing is worth nothing. Then I realized the true value of #buildinpublic.

I used to work remotely for years, and it's pleasant if your coworkers are great people. If someone thinks it's not possible, check this 👇

No, I'm not in Spain. No, it's not 20°C outside. I'm in Germany and it's -3°C

The husband asks his wife: "Darling, am I the first man you've slept with?" She replies: "Yes, honey, you are the first. With the others, I stayed awake all night."

The phrase: "You just need one right client for your business to take off" I didn't really get that until it happened to me. So I can say it's really true and you should never give up.

Will I ever use no-code platforms? Probably not. Not because no-code platforms are bad, but because I love programming.

A good software developer is able to look through the business's glasses. Many developers only pay attention to technology and disregard the business. Don't be one of them.

There is mine

I've created a "Web Developers" Starter Pack. Reply and I'll add you. Repost so we can reach more people! go.bsky.app/E8BtnuQ

There was a little plus button on users' profile images indicating that I don't follow them. Now it's gone I have to click on each person to check if I follow them. It's so annoying. Why was it removed?

For those who don’t know, @denicmarko.bsky.social is a living encyclopedia of all programming tutorials and tricks. I have no idea where he finds all of it, but hats off to him! 🥇
