Worked as a full stack developer on the company's internal content management system.The frontend was Windows desktop application (.NET Framework, WPF/MVVM + some JavaScript), and the backend was Web API + Lambda + S3 + DynamoDB + SQS on AWS. The main product is a subscription-based SAAS tool used by legal specialists. It includes a separate desktop application for UI designers and software developers to create content and UI forms for the main product (my team worked on that desktop application).This role was more or less standard brownfield application support and development.

Worked as a full stack developer on two long-running projects, both for the same big household name client (an electronics manufacturer). Both projects were in mid sized multinational teams of developers, QAs, DevOps and architects.The first project was design/development of a low level data collecting Windows service, tightly coupled with hardware (there was a custom machine-dependent component). The app included a desktop application to provide users with UI to control some advanced features of the device via the windows service.I worked on designing/development new features, mostly in the UI, but also on the Windows service component.Tech stack on the first project: .NET Framework 4.5-4.7, WPF, MVVM, SQLite, MQTT.The second project was application support of an airplane ticket booking system. The system is implemented on AWS, it gathers data from a few various sources, validates and enriches it, applies business rules and provides it to external consumers.Tech stack on the second project: Web API, Lambda, SQS, Cognito, S3, DynamoDB, TeamCity, SonarQube.Collaboration tools: Jira, Confluence, Slack, Git.

As a frontend developer, worked on a publicly facing web application, which was a part of a web authentication system used by Mercer's clients.Also did some development on the backend and database layers of the system.The project was about extending the functionality of the existing system, but mostly about getting the UI interface in line with the client's requirements (superannuation industry).Tech stack: C#, ASP.NET MVC, Oracle, IIS, jQuery, Bootstrap, Jira, TFS, Git.
