Selfie

I've started my professional career in a far 2002 on a position of "Systems Engineer" and was involved in a continuous code development/improvement/upgrade of city-wide client-server system used for collecting, sorting/grouping, processing and reporting of the utilities payments data. There were many technologies used but the key roles were played by (in order of being in development): FoxPro, dBase, SQL, HTML, ASP, JavaScript. Also most parts of the system infrastructure components were significantly improved and upgraded to run as the Visual FoxPro desktop applications with modern windows-styled interfaces built from set of visual components.

At present I have advanced knowledge of 5+ programming languages (JavaScript, Node.js, PHP, Perl, ASP, Visual FoxPro) and related fields (Linux, Bash scripting, HTML, CSS, MySQL, MongoDB, Docker, Redis, GraphQL, RabbitMQ, Git, Nginx, Apache, etc.). Websites creation, Open Source projects deployment, applications development, building, testing and improvement - these are the skills I work with daily. I'm constantly improving my abilities in it.

What I Do

During last few years I've been working as a full-stack specialist providing gathering and transformation of customer's business requirements into well-documented technical requirements of product functionality which tech-staff can easy read, understand and implement.
Excellent analytical and research skills, ability to explain complex concepts in easy-to-understand language - allow me to communicate actively with all company departments involved in process and identify most effective architecture solutions which provide maximum performance in a minimal costs.
I am passionate about clean and elegant code and believe that laconic documentation in conjuction with detailed descriptions of workflows and rules - saves not only time but money.
Years of on-hands experience with various kinds of high-loaded systems, built on top of modern web-technologies makes me strongly believe that development of smart, qualitative and useful software with a friendly user interface - is the best profession!
