A general advice would be curious in multiple things in different domains (tech, sport, politics, literature etc) be well articulated, confident and most importantly look happy.

My anecdotal advice is to change environment. Depending on where you move to the demographic (men/women ratio), race preferences and what is considered as interesting changes. As an engineer in engineering university, I had more luck on dating apps focusing on women from non-tech field with different men/women ratio. As a half-asian guy, I had way more success in an Asian country than a predominately white country. (independent from race/age of the women)
