As an Engineer, I have delivered a plenty of projects in various business domains, such as FinTech, AdTech, Marketing automation, Travel industry, Recruitment and HR, Telecommunications. I create robust, scalable and efficient Enterprise level applications of high complexity, intended to run within both classic on-premise environments, and in popular Cloud platforms, using such popular Backend programming languages as Java, Go, Python, PHP, and Javascript/Typescript with Node.js. I have experience using popular frameworks for each of these languages, such as for example Spring (several components) and GWT for Java, Django for Python, Symfony and Laravel for PHP, Expess.js with Node.js and others. Typically nowadays the Backend I use to deliver is a number of microservices with one or more exposed APIs, most often HTTP REST. For the Frontend, I have experience creating complex Web based dashboards using popular Javascript / Typescript based solutions, such as Angular 2+, React.js, and a big variety of different libraries. As part of architecture and design phase, I actively participate in the discussion of an upcoming solution, discovering and digging into the problem that we are trying to solve, providing you with comprehensive recommendations and coming up with a fully fledged design proposal, development phases and their estimation, as well as corresponding documentation afterwards. I also have an experience leading a small development team, providing it with an appropriate task splitting, basic engineering management, tech guidance, code reviews and support. As a supporter of "you build, you run" philosophy, I have a practical exposure to the DevOps, setting and using the CI/CD pipeline, with an active usage of IaaC tools, such as Terraform or Ansible. I actively use Docker in all the variety of possible ways: for development, testing, deployment, and in production - as well as have Kubernetes experience. Looking forward to working with you!
