As a project team leader, I efficiently coordinated and guided the efforts of the engineering, product, and design teams, working closely with the Lead Project Manager, Lead Product Owner, Head of Web Development, Director of Engineering, COO, and CTO across both business and infrastructure projects. Established and maintained an effective, code-quality oriented, conflict-free, and motivated work environment. Together with the team we developed a set of projects successfully from the beginning, including system design and analytics, all the way until the release.

As a Senior Full Stack Software Engineer and Lead Full Stack Software Engineer, I held a wide range of responsibilities. These included performing the R&D process, system analytics, prototyping, and complete implementation of software solutions and applications from scratch. Additionally, I refactored and improved existing solutions, addressing both technical aspects and product considerations.

I was accountable for developing and refactoring of several components for Intelsat APS (Asset Planning Suite) web application - an integrated system for a management of satellite communications carrier. The system gave an ability for managers and operational teams to plan and administrate satellite networks. APS supported complicated interaction between several modal dialogs and/or browser windows, that shared one session with a complex domain model. It has backend based on ASP.NET (C#) stack and frontend based on custom created Typescript framework. We worked as a Scrum team and strictly used testing (unit and integration) and functional programming practices during development.For more details about this project please see APS project in the Projects section.
