People who had gap in their resumes, how did you get your job after the gap and how did you justify the gap?

Currently, I've a gap of 1.5+ years. I was working on my own SaaS project from the past 8 months with no revenue and it's kinda pre-launch.

I've updated my resume stating the experience under freelancing. And I got few calls from the recruiters but when I told them that I'm freelancing and the revenue is not consistent they just ghost me. It has happened 3-4 times now.

My tech stack: MERN, TypeScript, Svelte, Tauri, AWS, Docker, PouchDB, PostgreSQL, Python, FastAPI.

Prior to this I've worked for 11 months as a Frontend Engineer mostly on react and is proficient in it.

How can I overcome this any advice would be of immense help.

Thanks.
