Sr. Backend Developer at Perceptyx
Czechia
Summary
👤
SeniorDenis Shaposhnikov is a senior backend developer with 14 years of experience specializing in Go, Redis-backed high-throughput systems, and FreeBSD infrastructure administration. He has a strong track record delivering scalable, concurrent services—most notably refactoring Perceptyx’s survey backend to handle hundreds of millions of responses per day using async SQL, distributed caching, and multi-datacenter load balancing. Comfortable across languages (Perl, Python, Ruby, Lua, C/C++) and databases (MySQL, PostgreSQL, Cassandra, MongoDB), he blends deep systems and networking knowledge (FreeBSD, Cisco, OSPF/BGP, firewalls) with practical DevOps skills. Currently based in Czechia, he seeks fully remote Golang roles (EU/US) and has recent contractor experience building serverless and backend components for game studio and enterprise clients. Colleagues rely on him for turning complex performance and reliability requirements into maintainable, production-grade solutions.
