Optimize JSON Responses in Express API
Skills Required
Description
Optimizing our Express API's JSON responses is a priority to improve the overall speed and performance of our platform. This task is aimed at reducing payload size, eliminating redundant data, and ensuring our endpoints return only what's necessary.
You’ll be diving into our existing Express.js codebase to streamline how responses are structured. Familiarity with MongoDB queries and optimizing Mongoose population is critical.
Some of our endpoints are returning deeply nested structures that can be simplified without losing necessary data for the frontend. We’d love a developer who understands what frontend teams actually need — and can cut through the noise.
Expect to work closely with our Firebase and frontend teams to make sure changes won’t break any rendering logic on the client side.
Half of the work is cleaning up the logic, and the other half is ensuring consistency across all endpoints.
This isn’t just about shrinking payloads — it’s about making the data more predictable, readable, and useful for every consumer of the API.
We’ve already benchmarked some routes and know where the bottlenecks lie. You'll be given profiling data to guide your work, but we welcome your ideas too.
If you’ve worked on projects where performance and clarity in APIs mattered, that experience will be invaluable here.
Bonus if you’ve done response compression, partial document returns, or intelligent field selection based ...
