I have strong background in data structure and algorithm (heap, tree, graph, dynamic programming...), concurrency (coarse – grained – free locking and memory barrier), deep understanding how OS, Database and popular Open source (Kafka, Lucene, Casandra..,) work internally (how they are implemented). I quickly read/understand source code of complex system.
Familiar with Raft, CAP theorem, sharding and leader election. machine learning algorithm.
