Experienced in developing (as Systems/Application Architect, Team Lead and Senior Developer) and deploying (as DevOps) distributed systems using microservices architecture, network services and backends for websites/mobile apps in Go. I'm developing software since 1989. I work as Perl/Web Developer since 1997. Since 2009 I'm using microservices architecture for most projects. Since 2015 I use Go language. Development priorities: code simplicity and clarity, reliability, security, efficiency. I've experience with AWS, Docker Swarm, Apache/Nginx web servers, edge proxies (Traefik), SQL (MySQL, PostgreSQL) and NoSQL (Cassandra, ScyllaDB, Redis, Aerospike, etc.) databases, event queues/brokers (NATS/STAN and several custom ones), non-blocking/async I/O, event-oriented and concurrent programming, service-oriented and microservices architecture, distributed computing, automated testing, metrics/alerting/monitoring (Prometheus, Grafana), gRPC/OpenAPI/JSON-RPC/REST, outdated HTML/JavaScript/CSS, … I work as Linux admin since 1994. Experienced in developing and supporting own Linux distribution from scratch (2001-2004). I've strong focus on security and since 2004 use Hardened Gentoo Linux. Experienced in developing large systems (50000+ man/hours) as Systems Architect and Senior Developer. Experienced Team Leader and Manager for small team (about 10 developers/QA). Also I'm author of many articles (mostly in Russian) and have small experience (about 6 months) as Top Manager in software company (about 200 employee). Since 2001 I'm working as full-time freelancer. I never agree to work which must be done quickly in exchange for quality. I like to do things in the Right Way and prefer simplicity and minimalism. I'm interested in tasks related to distributed and/or highly concurrent systems. I'm looking for long-term business relationships with customers.
