Ask HN: Where to Go from Here?

Was hoping the hn community (which i've grown with over my decade+ career) would provide some original insight - I've been a backend/jvm/low latency engineer for a long time. I specialize in indexing the web and providing it to downstream processes in warc format. My current role involves upleveling junior engineers as the system is pretty mature at this point and I probably won't be promoted staying here. I could see myself building crawlers for a while but I'm not seeing any startups that need this skill. Where would you recommend I look for the next interesting project involving low latency jvm languages (like yc's backed questdb)
