Common signs: slow pages, a busy database and repeated identical queries. Usual causes: no caching layer and expensive queries on every request. What we do: add Redis caching with sensible expiry and invalidation. What you get: faster responses and before/after numbers.
Our Redis caching setup makes your app faster by storing the results of expensive queries and API calls in memory, so they don't run on every request. A Codersarts engineer finds what to cache, sets up Redis, adds caching to your code with safe expiry and invalidation, and measures the speed-up. Fixed price from $199 with 1-day delivery.

What Is Redis Caching?
Redis is an in-memory data store that apps use as a cache: a fast place to keep results that are expensive to compute or fetch. Instead of querying the database on every page view, the app checks Redis first and only goes to the database when the cached value is missing or expired. Done well, it cuts response times and database load sharply.
Signs You Need Caching
The same pages or API calls are slow for every user
Database CPU is high during busy hours
Dashboards and leaderboards recompute the same numbers on every view
You call a slow or paid third-party API repeatedly for the same data
Sessions are stored in the database or on one server
Why Apps Need a Cache
Repeated identical queries
Many users request the same data, and the database computes it every time.
Expensive aggregations
Counts, rankings and reports are calculated live.
Slow external APIs
Third-party or AI APIs add seconds to each request.
Sessions tied to one server
Session data on one server blocks scaling to several.
Quick Checks You Can Try First
List your 5 slowest endpoints and whether their data changes often.
Check whether your framework already has a cache layer you can switch on.
Add HTTP caching headers for static and public content.
Make sure database indexes exist before adding a cache.
If the problem remains, our engineers take it from there.
How We Add Redis Caching
Measure. We measure response times and database load before changes.
Choose what to cache. We pick data that is read often and changes rarely.
Set up Redis. We deploy Redis or connect a managed service, secured and monitored.
Add caching. We add cache-aside logic with expiry times for each data type.
Handle invalidation. We clear or refresh cache entries when the underlying data changes.
Measure again. We compare before and after numbers.
What You Get
Redis set up and secured
Caching added to your slowest endpoints
Expiry and invalidation rules for each cached item
Before and after response times and database load
Notes on adding caching to new features
Example result (illustrative)
A leaderboard page took 2.4 seconds because it ranked all users on every view. Caching the ranking in Redis for 60 seconds, and refreshing it when scores changed, cut the page to 120 ms and dropped database CPU by more than half.
What Is Included and Not Included
Included | Not included |
|---|---|
Redis setup or connection to a managed service | Rewriting your data model |
Caching for up to 5 endpoints | Caching every endpoint in a large app |
Expiry and invalidation logic | Redis hosting costs |
Before and after measurements | Multi-region Redis clusters (higher package) |
Pricing for Redis Caching Setup
Package | Best for | Starting at | Delivery |
|---|---|---|---|
Caching review | Find what to cache and how | $29 | 24 hours |
Redis setup | Redis plus caching for up to 5 endpoints | $199 | 1 day |
Full caching layer | App-wide caching, sessions and queues | $599 | 3 days |

Who This Is For
Apps with slow dashboards, feeds or leaderboards
Startups seeing high database bills
Teams preparing to scale to more servers
Apps calling slow or paid APIs repeatedly
What We Need From You
Repository access
Which pages or endpoints are slow
Where the app is hosted
Access to monitoring, if any
Code and data privacy
We sign an NDA on request, work with the least access needed, and never keep copies of your data after delivery. You own all code, configuration and notes.
Key Terms Explained
Cache hit: a request answered from the cache
TTL: time to live, how long a cached value stays valid
Cache invalidation: removing or refreshing cached data when it changes
Cache-aside: the app checks the cache first and fills it from the database on a miss
Common Mistakes We Avoid
Caching data that changes every second
Caching without expiry, so stale data stays forever
Caching per user when the data is the same for everyone
Leaving Redis open to the internet without a password

Frequently Asked Questions
When should I use Redis caching?
When the same data is read often and changes rarely, such as dashboards, product pages, rankings or third-party API results.
Will caching show users stale data?
Only for as long as the expiry you set. We also clear entries when the underlying data changes.
Do I need a managed Redis service?
Not always. Self-hosted Redis is fine for many apps. Managed services save maintenance for production workloads.
Is Valkey the same as Redis?
Valkey is an open-source fork of Redis that works the same way for most apps. We support both.
