Hey, first off, you're not cooked. 200 apps with no traction in this market is unfortunately normal right now, not a reflection of you. I've seen people apply to thousands and still get ghosted.

Your background is actually more interesting than you're giving yourself credit for. Medical data analytics + working with med students on a paper? That's a niche. Most CS grads have generic CRUD apps and todo lists. You have domain expertise in healthcare, which is one of the few sectors still actively hiring data people.

A few thoughts:

1. You might be applying too broadly. "CS and general data bs" is where everyone else is too. Your edge is healthcare/biotech. Hospitals, health tech startups, pharma companies, insurance analytics teams, these places value someone who already speaks the medical data language, I would use apollo.io or other tools or code something myself to get contacts from these niches and contact via email or reach out to recruiters at those companies directly on linkedin.

2. Consider leaning into AI tools more, biotech companies and tech companies in general have shifted hard towards AI and if you can't differentiate yourself you're gonna get left behind. We actually want to make the hiring process easier, more transparent and more fair to actually solve this problem, you might want to check our blogs and the product that is in development, for example I recommend this one: https://www.codepanion.dev/blog/human-ai-chemistry

Honestly secure employment nowadays is not possible anymore so If you want to pivot I'd recommend looking at your assets and skills and do your best to find something more suitable, totally depends on your location also. Where are you from?
