Ask HN: Lost in Life and at Work, Help?
4 by thrwlost | 2 comments on Hacker News.
I am 30 years old backend engineer, totally lost in life. What can I do: create CRUD/REST API over database. Trying to change my current job, but have fear of failing in new place, companies are asking for high-load experience, AWS, GCP, distributed systems, microservices, event driven architecture, some asking how many micro-services we have in current stack and so on. I work in fairly loaded system with over 1M daily active users, for which we create analytics, with small team, with good old RDBMS database. No fancy distributed systems, no 1000s of microservices (just 4-5 services are working really fine for us), no consensus problems (in case we need consensus, simply lock database table and serves us fine for quite long time, not enough? just lock different table based on hash of key). I assume natural way to grow as an engineer and not regret at 40 years age is to become expert in some area, could be storage engines, some types of NoSQL, in-memory caches, maybe AWS/GCP expert or person who understand leader election/gossip/.. type of things really well. But I am afraid I should sacrifice lots of time from my family, from my kids and wife to become an expert in a field which I am not currently employed. What can I do?
