Sebastian Heitmann

tl;dr accomplished developer and consultant. Writing about tech, entrepreneurship and mental health. Last year at this time, I officially started my solopreneurship. This was an important moment for me. I closed the chapter about my burnout and the following depression. It wasn't easy, but I landed a client, and I was able to sustain myself. I had many different goals, but as usual, it took longer than expected to achieve them. Now, my professional site is live, and I have started writing actual content. I am still developing my product ideas. This is nothing singular or astonishing in itself. I know that. But overall, I am very glad to have started posting here, and I am still around, so expect more to follow. Feel free to follow and tell me what you are up to! cya ✌️

@dev_maims Still the best portrayal of a coder.

Real 😹

i really hate that the models were trained on your code

@HaseebGVA What's that about?

@e2e_developer Content creator Marketing my new genre Rhoology

If not tech, what would you be doing right now? #repost

@sami_babar463 How long did it take to see the results?

What I did in 30 days to get a client 33,000% traffic growth: → Fixed every technical SEO issue on the site → Built one tight topical content cluster → Targeted keywords with intent, not just volume → Internal linked everything together That's the whole playbook.

@techyoutbe You can and should talk about it, though.

Don’t work/post to get attention…work to solve problems….Rest will follow automatically 👍

@sudoingX What to do with two dudes?

buy a gpu or two dude!

@coolcoder56 🥲

I have realised one thing most people in Indian tpot are jealous of each other and hate each other for no reason. Rather than supporting

@BatsouElef Immensely. The only thing I don't do AI assisted is doom scrolling this app 😅

How’s AI changed your workflow?

@katarinaore Nice! Congrats 🎉

I got my FIRST PAYING USERS for my first ever iOS app in April 2026!!! I earned a whopping total of $10 of revenue ($8 in profit after stripe fees) from my first 6 customers It was even before the app was live on the App Store, purely from me talking about it on X Honestly I think it means more than if it was $100,000!

@yuhasbeentaken This is what AI changes. And I am surprised how many people are still not using AI in their workflows.

I run a content growth agency in China. One of my clients has an economics degree from Cornell. After moving back to China, she lost access to Claude. Today she told me it would take an entire afternoon to finish an ad brief. I pushed her (hard) to use Claude anyway. She got it done in 15 minutes. The whole thing feels a bit absurd 😂

@dastagirshaikhh What do you expect from a startup community? If you want to sell your product, go to your customers, not your peers.

90% of startup communities are just founders talking to other founders who will never buy their product.

@marcs_dev I haven't tried it out, but Clever Cloud looks interesting. I am hosting my site on S3 via Scaleway, but that is not really like Vercel or similar.

Question: Is there any good hosting provider similar to Vercel or Render, but based in the EU? 🇪🇺

@dreamsofcode_io Whenever I work with Java or Kotlin, I open IntelliJ. For almost everything else, I work in a terminal. In the end, I use whatever has a positive effect on my productivity.

TUIs make a lot of sense in developer tools. Not because they are superior (debatable), but because they keep you in the terminal which is (for better or worse) the ultimate developer environment. It’s simple, scriptable, remotely accessible, and enforces good practices (text based output).

@AsadAljabane With consistency, someone can create momentum. You show up every day, so you are able to seize the opportunity when it comes your way.

Having slow days is incredibly mentally difficult as a founder… but once you cross that threshold, you realize consistency matters more than momentum

@yacineMTB Have you tried not being sad?

i'm sad

@icanvardar Someone needs to maintain all the produced slop.

if ai is taking away jobs, why does anthropic keep hiring so much?? 😭

@ThePrimeagen Why do we take the opinion of an evolutionary biologist as an expert opinion?

🚨🚨Breaking Smart people are dumb too

@ThePrimeagen Doesn't mean you can't use AI to help you get started.

A small piece of advice to up and coming creators. Do not let LLMs write your scripts. Find your voice, even if its semi-coherent like mine. Its better than just sounding so average

@comfort_prima Moving away from programming. The business side is a lot messier.

What is the mistake you made in Tech as a programmer that taught you a big lesson?

@comfort_prima I already have 😎

@e2e_developer Grab the opportunity

I randomly discovered that sebastianheitmann . com and sebastian-heitmann . com have no owner... Or should I say... had no owner 😎
