Software Engineer

Israel - Last active: 1 day ago - Tests: 2

Dear Client, I have 9 years of experience working in the industry and have developed for the Web as well as native applications. I am what you'd call a full stack developer and I can single-handedly deliver whole projects start to finish. In spite of this, I like the dynamics of working in a team and that's my preference when possible. I'm interested in accepting work in the Clojure language and in the following: Server side development on the JVM (Clojure, Java, Spark, Kafka, Cassandra, Storm, Redis, ElasticSearch, Samza). Client side applications in ClojureScript or Javascript (Om, Reagent, ReactJS). I strongly believe in delivering robust, clean and tested code. I am also a technology enthusiast and thus I'm always glad to deliver projects using cutting edge tools like the ones mentioned above.
