What’s your go-to data structure when a brute-force approach hits TLE?

[Oghenetega Adiri @adiri_tega]

Some LeetCode problems look deceptively simple... until the Time Limit Exceeded (TLE) hits. ��

Just solved 239. Sliding Window Maximum.

My first intuition? Track the max, and rescan the window when it drops off.

Result: O(N . K) time complexity. TLE! 💀 🧵👇

[Oghenetega Adiri @adiri_tega]

The fix brought the solution down to O(N) time and beats 93% of solutions on LeetCode 😌

It’s always satisfying when a problem forces you to look past the "quick fix" and get clever with data structures.

Don't just set a random 5-minute TTL and hope for the best. Design event-driven cache invalidation when state changes.

Which cache strategy do you rely on most in production?

[Oghenetega Adiri @adiri_tega]

Caching can drop your API latency from 250ms to 12ms.

It can also serve stale data to thousands of users if you pick the wrong pattern.

Here are the 3 core caching strategies every senior engineer must know 🧵👇

3. Write-Back: App writes to Cache immediately. DB is updated asynchronously later. Blazing fast writes, but high risk: if the cache node dies before syncing, data is lost.

Rule of thumb: Scale your domain boundaries and team structure first. Scale your underlying infrastructure second.

What’s your take, monolith first or microservices from day one?

[Oghenetega Adiri @adiri_tega]

We didn’t need microservices. We just needed to stop treating our monolith like a dumping ground.
Here is why splitting your database and services prematurely might be slowing your team down 🧵👇

[Oghenetega Adiri @adiri_tega]

Before distributing your system, build a Modular Monolith.

Enforce strict domain boundaries inside a single codebase. If you can't keep modules isolated in memory, splitting them across network boundaries will just create a distributed monolith.
