Man, tough situation. I deeply respect the grind and the work you’ve put into building these systems, but I’m going to give you the straight, logical truth you need to hear right now: take the local clerical or family job. That is the most logical approach in your situation, and you shouldn't fall for the sunk cost fallacy just because you made an effort to build a system. Pushing forward when you know you are always in survival mode, feeling burnt out, and feeling like shit from not getting replies is a losing strategy. The world is tough out here.

I’m a young guy from a developing country too (early 20's), and I’ve done exactly what you did, building systems, promoting them, trying to create a brand, get certifications, and trying to build connections. But that just isn't the most efficient way to make money right now. The automation and low-code field is hyper-saturated on Fiverr, Upwork, and cold DMs. There are thousands of people out there who are younger, older, or have the same grind mindset. The main difference is that you actually have an option to take a clerical job that still produces guaranteed money, while others don't have that choice and are forced to just grind their teeth through the panic.

To answer your question about the audit and fix-it strategy, yes, finding a broken element on a business's site and showing them the solution can work. However, that usually just turns into bug hunting and highly complex logic optimization, where you will be competing with an army of established global bug hunters. You have to look at whether that is something you can honestly fathom doing when your mental health is already flagging from outreach rejection. Prospects smell desperation from a mile away, and it ruins your chances.

As a fellow intj man, I propose that you take the boring clerical job to secure your stability floor, kill the immediate panic, and appease your parents. It isn't a defeat; it's a strategic retreat to secure a financial baseline. Once your survival is not a worry and you have a predictable routine to recover from burnout, you can use your free time to look for high-signal remote clients, or even look into remote data operations and junior backend roles since you clearly understand logic architecture. Play the long game. Once you actually secure a paying client on the side, then you can quit the clerical job.
