I really enjoy(ed) Neal Asher's "Transformation" series (https://en.wikipedia.org/wiki/Dark_Intelligence) and the Polity universe. I enjoy sci-fi series, interesting spacecraft, compelling aliens and am a sucker for machine-based intelligence. This series combines all these and re-engaged in sci-fi. I went on to read most of Asher's other books including "Agent Cormac" and "Spatterjay" series.
