I designed and delivered training in advanced web development techniques for a one-year work-study training program attended by seven successive cohorts of 10-20 students.

The training covers web and mobile development (TypeScript, Node.js, and React) through practical application, with a focus on key skills like automated testing and DevOps practices.

I wrote lectures, guided tutorials, and development exercises ("quests") on a variety of topics applied to Node.js and React, including:

• the GraphQL-Apollo stack applied to a React app coupled with an API server

• setting up a React application with server-side rendering (SSR) and code-splitting by route with Next.js

• global state management in React applications with Redux, Context API, and client-side Apollo cache

• DRY implementation of business logic classes with TypeORM and type-graphql to define both the database access interface and the GraphQL API schema

• automated testing (unit tests, integration tests, end-to-end tests, snapshot tests with Jest, React Testing Library, Puppeteer, SuperTest)

• continuous integration, continuous delivery, and continuous deployment, practiced with GitHub Actions

• setting up Node.js, Postgres, and nginx services using Docker and Docker Compose

• deploying and managing web service instances on a Linux server with caddy, systemd, journald

I designed and delivered training on various software development practices for groups of 10-15 students in bachelor's and master's programs:

• single-page applications with React

• automated testing with Jest, React Testing Library

• static typing with TypeScript

• version control with Git, GitHub

Each of these topics was covered in 12 to 30 hours of class, starting with a theoretical lecture and then practiced by the students with my guidance. Students were evaluated by submitting a practical assignment.

I conducted one-on-one training sessions with two professional developers, helping them improve in:

• test automation (Jest)

• static typing (TypeScript)

• functional programming (TypeScript)

• continuous integration (GitHub Actions)

Each session involved solving real-world problems encountered at work or adapted exercises.
