projects

Each card below is one piece of the same artifact, the Travlr Getaways MEAN-stack application. The code review came first; the three enhancement pages that follow it cover software design and engineering, algorithms and data structures, and databases. Every enhancement page opens with a short narrative, shows before-and-after code for the changes small enough to display, and links to the matching branch on GitHub so you can read the full diff.

Code Review

A walkthrough of the existing Travlr Getaways codebase and the planned enhancements across software design, algorithms and data structures, and databases.

Software Design and Engineering

Six enhancements to the Travlr Getaways MEAN-stack application that tighten the boundary between the public site, the admin SPA, and the API: a functional HttpInterceptor, environment-based Angular configuration, real user-facing error feedback, hardened CORS, and the removal of a deprecated HTTP client.

Algorithms and Data Structures

Five enhancements to the Travlr Getaways application that move work off the database and into the right data shapes: server-side pagination, an indexed single-document lookup, a price-field type migration from string to number, a BehaviorSubject-backed cache in the Angular admin, and a hardened JWT decode path.

Databases

Six enhancements to the Travlr Getaways data and authentication layer: a redesigned user schema, a migration from PBKDF2 to bcrypt, refresh tokens on a separate signing secret, a startup configuration validator, server-side input validation, and an API specification a new developer can actually read.
