i will not promote . What do you think of specializing in one industry to stand out when applying for technical roles ?

Pick an industry (eg:FinTech, HealthTech, PropertyTech) → deeply understand its problems → talk to people inside it → build something relevant → become visible to companies in that industry → use that knowledge in cold outreach and interviews. What do you think of this approach for getting a developer job? How would you rate this approach, and what do you think are its strengths, weaknesses, or potential problems? Also, if you were going to follow this approach, how would you: Deeply research a particular industry? Meet and talk to knowledgeable people working in that industry? Find real problems that people repeatedly face? Understand which problems are actually worth exploring or building around? I'm open to all perspectives. If you think this approach is flawed or there are better ways to approach getting a developer job, I'd be interested in hearing those as well.
