I decided to challenge myself in a way that I have been considering for a while now. Build a full-stack application in only 7 days, completely from scratch, to completely real and usable. Not just a tutorial project, a clone of something that already exists, but something that I have designed, created, and shipped by myself.
There’s something about coding projects like these that make them feel almost deceptively simple in the beginning. You think the hard part will be writing the code, but in reality, the hardest part is normally finishing them. Most people don’t fail because they can’t write the code… they fail because they never fully complete anything. They always stop somewhere between ‘idea’ and ‘almost done’.
So, I wanted to remove that entirely. I stuck to no over-planning, no perfect architecture diagrams, and no time wasted endlessly researching the ‘best possible’ stack. Just 7 days of building, documenting and continuing on forwards no matter what happens. This is Day 1.
Day 1 started almost exactly like you would expect. I was staring at my laptop’s blank screen, trying to decide what I was going to build. This part is always more difficult than people admit. Not because it is necessarily difficult to think of ideas, but because it feels like you have to have the perfect idea before you even begin.
However, I forced myself to follow one simple rule: if I couldn’t explain the project in one sentence, and why I wanted to build it in one more, then I wasn’t allowed to build it yet. That alone removed a lot of the noise. After cutting everything down, I ended up with a relatively simple direction: build a full-stack app that is actually useful, is small enough to build in one week, but also flexible enough that I can expand it later.
It was nothing revolutionary, just something real that I could actually build and improve on. So, once I had that clarity, I stopped planning and started building almost immediately.
For the first day, I didn’t focus on building features. I focused instead on setting up my foundations properly so I wouldn’t regret it later on down the line.
I chose a stack that prioritised both speed and simplicity: Next.js for both the frontend and backend, Supabase for authentication and database, and TailwindCSS for styling. I decided not to waste time deciding about tools; I just picked what let me move quickly.
I created the project, set up the basic structure, connected Supabase, and got the environment variables working. It doesn’t sound like a lot on paper, but this is the stage, when developing something new, that everything either goes smoothly or starts to become a mess later on.
There always happens to be a moment during the setup where things feel slightly messy and fragile, like one wrong configuration could break everything. But, after a bit of trial and error, I got it running cleanly.
That moment when the app finally boots without errors is always underrated. It is the point, where for the first time, the project stops being an idea, and begins to transform into something real.
My biggest win on Day 1 wasn’t building a feature, or writing some complex logic. It was simply getting everything to connect properly. The front-end loaded correctly. The backend responded. The connection to the database worked. There were no errors flooding my terminal.
It sounds basic, but these small confirmations mattered more than anything else early on to me. They were the things that gave me momentum. Without that, each of the next steps I took would have felt uncertain. Instead, everything felt possible.
Of course, my Day 1 wasn’t completely smooth. Even on Day 1, I ran into the usual setup issues: Environment variables wouldn’t load properly, there was some confusion over my Supabase setup, and some smaller decisions about folder structures that, looking back, I probably spent way too long thinking about. Nothing too major, just enough to slow things down only a little.
What I found most interesting was that most of these problems weren’t actually problems related to coding. They were setup problems. And setup problems always feel worse than they actually are, because they block everything else from moving forwards. Once I had that realisation, it became a lot easier to stay calm and focus on fixing things one by one, instead of overreacting and panicking.
Looking back at the first day, the main lesson I took from it wasn’t technical at all. It was all about my speed and momentum.
It reminded me that planning is only useful up to a certain point. After that, it becomes a delaying tactic cleverly disguised as productivity. Progress only really starts when you begin to build something that exists outside your head.
It also reinforced something that I have noticed before: that getting something running, even if it is in its most basic form, is far more important than making it perfect. Perfection can come later, but functionality has to come first.
Most importantly, it showed me that momentum is everything. Once the project is alive, even in a basic form, it becomes much easier to continue.
Day 2 is where things will start to get interesting.
Now that the foundation is in place, I will start to build actual features: real UI components, authentication flows and the first real pieces of functionality that turn my project from just a setup into something users could actually interact with.
Right now, I have the scaffolding. By Day 2, it starts to become a product.
