Project: Change Management Portal - application to track changes in production for audit purposes. Initial state: 10 years old code base. Goal: Seamless migration for the new system Team: When I joined the team, it was just three independent junior developers who are doing smth. Today it's a true team that behaves as a team: - everyone understands what they're doing and why - there is no my and your task - if there is a bug, then we think how to solve it regardless who introduced it - retrospective isn't just one more meeting but the place to discuss our wins and problems - before introducing smth, think how end-users will use this - introduce the code that you'll proud of - you shouldn't be ideal, sometimes it's worth to create dirty-and-fast solution and refactor it sooner than later P.S. all junior developers grew to the senior level within these 2y Tasks: 1) Development of the new version of the system and creating a plan for seamless migration from the old one 2) Development of fail-over protected, stateless and environment-independent service with the possibility for horizontal scaling. Actively used task queues based on Redis 3) Development of isomorphic and declarative ACL system 4) Development of the tools for data migration from legacy DB to the new DB assuming that both systems will work in parallel 5) Development of the new UI and its smooth integration to the old system in the first phase and then seamless migration into the new system (each section in the legacy system is a separate application, which is also a part of the micro-frontend application of the new system) 6) Blue/green deployment process for backend 7) Creation of the deployment process for the frontend (one bundle for all environments) and its support on the application level 10) Development of the API for the new UI and facades for seamless migration from integration with the legacy system to the new one 9) Creation of a plugin for the NestJS framework (https://github.com/klerick/nestjs-json-api). It generates CRUD with JSON API specification, including data validation and transformation using the TypeORM model. Based on this plugin, I created an SDK for clients (FE, API, etc). 10) Development of the log module allowing tracing requests by its traceID 11) Development of subscription for data updates on the backend using server-sent events and TypeORM 12) Development of auth service following OAuth2 specification and an extension for basic access rules based on the extended scope from the auth application 13) Development of server-sent events sharing for connection across browser tabs using a service worker. Also, I introduced the way to work with access tokens and authorization there
