I remember similar moment in like year 17... realized that I will never see myself as "a good developer".

Top 2% on Stackoverflow, coded multiple startups fully by myself, had years where I would literally code every day... and I would still fall victim to like "oh, but I'm not good at evaluating this random project in TypeScript, am I really a good dev".

Luckily, by that point it was already a year or so into this "Rockstar Developer" persona, so that started to take hold...
