Summary
I’m a full stack web developer with 10+ years’ experience in back -end and front -end. Also, I
have DevOps & QA skills.
About back -end
I’ve been programming since 2006. My first languages were Python and PHP. In 2011, I
started the development on Node.js. Then, in 2015, I tried TypeScript, and it proved
excellent. I also had a lot of practice in other back -end programming languages, frameworks
and technologies: Ruby, Go, Java (Spring, Spring Boot), Clojure, Webpack, GraphQL, REST
API, Babel, PostgreSQL (TimescaleDB, PipelineDB), MySQL, Redis, Tarantool, RabbitMQ,
Apache Kafka, Next.JS, Nuxt.js, Ne st.js, Git, Mercurial, Ajax, NPM, Yarn, Composer,
Symfony, Yii, Phalcon etc.
About front -end
My experience with React.js started in 2014, after years of working with jQuery, Vanilla JS
(pure JavaScript), and, of course, HTML + CSS. My practice with React + Redux began in
2015, and nowadays I use Redux -Thunk, Redux -Saga and React Hooks. Since 2016, I have
also been working with Vue.js, and I think, that it’s a not bad framework. And, in general, my
front -end stack is: React.js, Redux (redux -thunk, redux -saga ), Vue.js, AngularJS, micro -
frontend architecture , TypeScript, Babel, jQuery, JavaScript, HTML 5, CSS3, Bootstrap 4,
NPM, Yarn, Gulp, Grunt, Sass, Less .
About DevOps
Many times, I was in a situation, where I needed to configure the servers myself. At the
beginning there were simple bash scripts, but then I started to configure Kubernetes clusters
with Ingress, Flannel/Calico, Grafana, Graylog, Consul, Prometheus and many alert
me ssages. Of course, there were CI/CD (Jenkins/GitLab CI/Bitbucket Pipelines /GitHub
Actions ). Also, I have huge experience in AWS and DigitalOcean infrastructure , including
practice with Terraform .

About QA
My practice tells me that the human factor is the m ost common cause of errors in software
products. And I'm sure, that I should test my code using various testing strategies. At
present, I like to write different end -to-end tests (Selenium, Jest + Supertest, etc.), unit -tests
(Jest, Mocha etc.) and snapsho t-testing.
About Teamwork
I have a lot of experience in working with different teams including decentralized ones. Also I
was in a teamlead position and tried many teamwork methodologies, such as Agile, SAFe
(Scaled Agile Framework), Scrum, Kanban, Waterfa ll etc.
