🔴 RAW Process of Building a SaaS (Caching with Redis, Errors & Debugging)

Описание: In this video, I’m sharing my raw and real development workflow, how I usually tackle bugs, performance issues, and debugging in real time.

This is not a polished tutorial or something made to impress anyone. I’m simply documenting my journey as a developer. Nothing was pre-planned before recording — everything you see is on the go.

During the video, I ran into a performance issue and decided to solve it by learning and implementing Redis in one of the endpoints. You’ll see how I:

Identify performance bottlenecks
Debug Redis connection issues
Handle pagination in caching properly
Design and structure Redis keys

Think through problems step by step

This is just my honest workflow. how I approach problems and figure things out.
Context:
Project Context and Goal (0:13): The creator explains he's building a gym management SaaS to solve issues with handwritten registers in Pakistani gyms, aiming to learn new technologies.
Debugging an Initial Error (3:58): The creator encounters and resolves a members page.tsx error, demonstrating a real-time debugging process.
Identifying Performance Bottleneck (4:30): The creator notices slow loading times for member data, leading to the decision to implement caching.
Implementing Redis Caching Strategy (7:00): The core caching strategy is explained: first check Redis for data, if not found, fetch from the database and store in Redis.
Troubleshooting Redis Connection (8:46): The creator debugs and fixes a connection issue with the Redis server.
Witnessing Redis Performance Improvement (24:58): The video shows the dramatic speed increase in data retrieval after implementing Redis, with response times dropping to milliseconds.
Designing Dynamic Redis Key Structure (26:51): The creator explains the importance of dynamic keys (including gym ID, page, limit, search parameters) for effective pagination and data retrieval.
Applying Redis to User Profile Data (43:38): The caching strategy is extended to improve the loading speed of user profile data.
