I am a Software Engineer with experience in frontend and backend development. I have worked on microservice systems, transaction flows, and message queues that keep data in sync across services. I am currently on an international team, integrating AI into products in the education domain, and using AI in my daily work to be more productive.

      Publish David's post and watch it reach his followers.The post is written. One record, holding what David wrote.A feed record is created from it. One per post, and the only copy that ever changes, so the distribution records below never have to be rewritten.The change becomes an event on Kafka.A consumer picks the event up and loads David's follower list.Every follower gets their own distribution record, written in batches of 500. That is fan-out on write: pay once here, so reading a timeline is cheap forever.Likes and comments only update the feed record. The distribution records below are never rewritten.David deletes the post. The delete is published as an event and travels the same pipeline.The consumer removes every follower's distribution record first.Then the feed record.And last the post itself.
