Expert Node.js Backend Developer Needed for Caching Mechanism – Copywriter Job
Freelancers Only. We are interested in individual freelancers only for this project. Agencies need not apply.
We are seeking an experienced backend developer specializing in Node.js to implement a caching mechanism for our app, "Going Solo." The app connects solo travelers, enabling them to meet like-minded individuals, participate in group activities, and plan trips together.
Key Responsibilities:
– Design and implement a caching system to reduce redundant API calls.´
– Ensure that data from initial API requests is saved to our AWS database.
– Set up a retrieval system that checks for existing data in our database before making any new API requests. If the data is available, it should be served directly from our database.
– Develop a system to update the database with new data from API requests when not previously available, enhancing our dataset over time.
Requirements:
– Proven experience in backend development with a strong command of Node.js.
– Familiarity with AWS services and database management.
– Ability to create efficient data caching mechanisms to optimize performance and reduce costs.
Project Specifics:
– The project involves working with paid APIs (details will be provided upon hire) to retrieve location-based data.
– The primary goal is to minimize API call costs by implementing effective data caching strategies.
Detailed Feature Explanation:
We are developing a caching mechanism to optimize our app's performance and reduce costs associated with redundant API calls. Our app currently retrieves location-based data from a paid API service. We've noticed that many of these API requests are redundant, often requesting information for the same locations multiple times.
Objective:
The objective of this project is to minimize these redundant API calls by implementing a caching system. This system will save the data retrieved from each API call in our AWS database. Subsequent requests for the same location will first check our database to see if the data is already available. If it is, the app will use the stored data instead of making a new API call. If the data is not in our database, the app will proceed with the API call, retrieve the required data, and then save it in our database for future use.
Expected Outcome:
By implementing this caching mechanism, we aim to:
– Decrease the number of redundant API calls.
– Reduce the costs associated with these API calls.
– Enhance the responsiveness of our app by providing quicker access to previously requested data.
– Gradually build a comprehensive dataset within our own database, which could potentially improve the functionality and scope of our app.
This approach not only optimizes our resources but also ensures a smoother and faster user experience by reducing the wait time for data retrieval, which is particularly crucial for enhancing the experience of solo travelers using our app.
