Sleep and Health

Web app that lets users track their hormonal medication intakes and measurements, and correlate the data to see the effects on their sleep

What it does

Allows a user to log any relevant (hormonal for now) medication they are taking, and results from hormone testing kits (Mira). Oura integration is being currently added. The idea is to let the user both see the effects over time, and allow them to see their sleep patterns and how they might be affected by hormones.

Why I built it

A friend of mine who is under HRT has noticed the big effects it has on the quality and quantity of their sleep, and although there is a basic Mira-Oura integration, it’s not really useful to actually extract the required information. Moreover, I was looking for a project to play around a bit with Flask and modern React as a learning project, so that seemed like a good fit.

How it's built

Tried a more structured agentic workflow in the beginning, based on Matt Pocock’s skills, including more advanced grilling / brainstorming, a shared context language, and splitting into vertical slices / GitHub issues to be tackled one at a time. Using Flask, React, TypeScript, Tailwind and PostgreSQL, all of them cause I wanted to get a bit more experience with them. Deployed on my Personal Playground.

Challenges / What I learned

I guess a lot of what I learned was focused on improvements to my agentic workflow. Extensive talking / brainstorming beforehand can actually help surface things about the features you are building that you haven’t yet thought of. Using the skill grill-me-with-docs, which attempts to set up a shared domain language with AI over time, has proven very useful, as it forces me to be less ambiguous. Even when things are confused in my mind, it surfaces those confusions. So, even if you are not using AI for any of the coding, I think that part can be very useful.

I am expecting more to come here, as this is a learning project, and I am coming in better contact with many technologies I haven’t used in big projects before, so perhaps I will update this in the near future.

After all, we never stop learning!
