I joined this project when there was nothing but an idea in the client's head. He wanted to create a new social network where users could receive income from their personal content.

Such an idea required us to build a highly secure, transparent, and trustworthy system. We decided that blockchain technologies can help us achieve that. I learned a new concept of working with blockchains and NFTs, which is patented now.

After two months of intense work, I clarified the requirements and business vision, prepared a specification and architecture design for the project, and built a development team for it. We went with microservices and Kubernetes for scaling.

Since I was the most experienced development team member, I took on the most complex tasks. In the meantime, I managed the other three developers, helped them solve issues, and worked with the marketing team to clarify requirements and direction.

This approach allowed us to release the product four months after the start, doing things quickly and not forgetting about best practices such as code quality, documentation, tests, and CI/CD. The system was launched and started to bring income within three months.

During COVID-19 times, my friend and I figured out an idea of a service we could provide for business people and artists in Montreal.

We researched what people are looking for, who competitors are, and what we can offer. We used a progressive web app solution to bypass Google Play and Apple Store limitations and fees and share users' business cards with just a link, which magically converts to an application.

I designed the system's architecture, configured hosting on Google Cloud, and created the back end with Ruby on Rails. In addition, I found and managed a UI designer and several Ionic 4 developers to build the application's front end.

For more than five years, I worked as a part of Toptal's core team, contributing to developing and improving an enterprise product. I was surrounded by a large team of top-level developers. I was also a part of a small sub-team of experts whose job was to find and fix performance issues, improve the quality of life for the entire platform, and research paths of potential evolution for it.

I mainly worked with Ruby, digging deep into Rails and several other libraries. My contribution resulted in a significant performance and stability increase, as well as a redesign of several parts of the system.

But it wasn't only about Ruby and Rails—I learned a lot about other technologies and solutions, including Python, Django, Jenkins, Kibana, and Grafana.

A virtual appliance that helps companies and organizations send and receive large files fast and securely. I have been hired as an expert FullStack Ruby on Rails developer.

My contribution includes almost all Dropbox-like features of the application and significant application rework to improve its performance and stability, as well as integration of analytics.
