For work projects I use primarily .NET, MySQL and Kafka. I enjoy working with Redis, Postgresql, Prometheus and Elasticsearch.
I also have minimal Python skills (wrote several simple scripts), worked on couple of Scala projects, now in process of learning Pulsar.
Sometimes I feel my math skills are not where I would like them and read about algorithms and statistics.
I am interested in software development practices and techniques, like unit/acceptance testing, algorithms, data structures and distributed systems.
