I’m building out the next round of services for Inboxlogy and need a back-end developer who lives and breathes JavaScript. Your main focus will be Web API development in Node.js—everything from designing new endpoints and modelling data to optimising performance and writing tests. You’ll work closely with our front-end team, turning product requirements into stable, well-documented routes that plug cleanly into our existing architecture. Expect to spend your days refining business logic, implementing authentication and authorisation, wiring up databases, and keeping our CI/CD pipeline green. Acceptance criteria for each feature: • RESTful or GraphQL endpoint returns the expected payload and status codes • Unit and integration tests cover core logic (minimum 80 % coverage) • Inline JSDoc plus a concise README for every service added • Dockerfile updated and builds successfully in staging If you’re comfortable choosing the Node framework you feel is best for the job and can communicate clearly in pull requests, I’d love to see your GitHub or a code sample that shows how you structure an API.

From your project description, it's clear that you need a backend developer who is well-versed in JavaScript and can adeptly handle Web API development in Node.js. Luckily, Node.js and JavaScript are two areas of expertise that I have honed over my 7 years of web development experience.

When it comes to backend development, my approach is thorough and comprehensive. I ensure a minimum coverage of 80% for unit and integration tests, incorporate inline JSDoc and concise README for every service added, and successfully update Dockerfiles for staging. Plus, as an experienced user of version control platforms like Git, GitHub, and Bitbucket, validating my works has never been easier. In conclusion, through my years of working with various project management tools like Trello, Asana, and JIRA I have cultivated an outstanding capacity to communicate effectively on pull requests - another critical aspect of your requirements.
