Frankly, most of these are not your issues. If you underperformed and were fired due to that in all 3 roles, it’s a different story. That’s not the case here. You’ve had a series of bad luck.

Startups do have a high failure rate. I was involved in a leadership role in a Startup where I worked 80+ hours and it was mentally and emotionally exhausting. I had to quit for my own mental health.

It happens.

Your resume is not a red flag. It’s how you tell your story. If you’ve been laid off because of issues outside of your control, it’s not on you to worry.

Don’t internalize this. Learn the lessons and move on.

I would encourage you to hire a career coach who can help you craft a compelling story about your experiences. They will help you identify your core strengths and provide some coaching. Your challenges are not technical, but mental/psychological (and btw it’s normal for someone who has been through what you’ve).

I wish you the best in your next adventure.

I have tried both Upwork and Word-of-mouth (personal network).

These have been my best channels.

Cold outreach has not worked for me at all.

People only pay if the product does something stellar compared to what they can get for free.
