Development of a new platform for bank traders. The idea of the UI part of this platform is to have the possibility to run it either in a browser environment or in a desktop environment. From a technical perspective, it was achieved by using ReactJS / Electron / OpenFin and unifying the API between the environments. Key points: - Development of the UI part of the new platform in a limited amount of time (3 months). This platform supports the launching of multiple frontend applications both from desktop and browser environments in a centralized manner using Electron IPC and window.postMessage. - Complete refactoring of the key element of the system called Director which is responsible for coordinating all other elements of the system as well as supporting web socket / HTTP connections and their cancellation/retry policy. This refactoring involved the introduction of the Redux state into the project. - Development of reusable and highly customizable shared React components for usage in various front-end applications inside the company. These components were wrapped into a Storybook and had two themes — dark and light. - Migration of multiple frontend applications to the newly created React shared components. - Providing an adequate unit test JavaScript code coverage for most of the projects I was involved in.

Key responsibilities: - Acting as a cross-team architect providing architecture guidance for the UI development across the company, further architecting, developing, and leading the UI architecture and components to support EIS products and platforms. - Leading/contributing to architecture, design & code reviews, guiding and helping about 30 frontend developers across the company. - Acting as a technical lead of the UI Infrastructure team which was formed specifically to identify and solve frontend cross-team technical debt items like the development of a shared components library. - Communication with all the interested parties like product strategists, analysts, team leads of other teams, and consulting frontend developers of the company’s large clients about the usage of our frontend components inside their applications. - Presenting the key frontend team achievements and plans during the weekly calls with management and client representatives. Key achievements: - Organized UI Infrastructure team and proved its necessity to management after a couple of successful sprints. Initiated the usual scrum setting for this team by organizing its work via sprints, stand-ups, sprint planning, and retrospectives. Additionally, I was providing periodic digests of team achievements for management and all frontend developers of the company. - Researched, identified, and documented the weak sides of the current frontend architecture alongside the proposed solutions (for example, state management replacement). - Done the upgrade of TypeScript from v2 to v3, React from v15 to v16, ant.design from v2 to v3, and some other minor libraries for the major frontend applications of the company. Additionally, guided other frontend teams and client teams regarding these upgrades in the form of migration guides and personal communication. - Migrated from multiple monorepos repository to one single monorepo by utilizing yarn workspaces and lerna. As a result, the development experience...
