Outside school, nobody cares how much you know. They care about what you can do with what you know

We moved from basic APIs to Agent mastery. Proud to announce TelexLinter is live on #TelexIM. Learned to build tool-equipped AIs with @mastra and implemented a custom JSON-RPC (A2A) Gateway. #hng

Just completed my Stage 0 backend task for the #HNGi13 internship Built a simple /me API that returns: __ My profile __The current time (UTC) __A random cat fact It was fun playing with Express + TypeScript and integrating an external API. #HNG #BackendDev #NodeJS #BuildInPublic

Just hooked up my domain to Vercel! Pro tip: DNS changes take time, so don’t spam refresh like I did 😂. Set your A record & Cname, sip some tea, and let the internet do its thing. Live now at! check my bio #WebDev #Vercel

Project Spotlight – KharonPay and the Future of Payments in Africa We’ll be exploring how @KharonPay is addressing Africa’s biggest payment challenges and what the future of transactions could look like. 📅 Wednesday, Sept 24 🕕 6 PM (GMT+1)

Day 5 of SOLID: Dependency Inversion Principle (DIP) High-level modules shouldn’t depend on low-level ones. Both should rely on abstractions (like interfaces). Why? It decouples your code, making it flexible & testable! #solid #oop #learn

No class should be required to implement a method it does not use

Day 4 – Interface Segregation Principle (ISP) <Clients shouldn’t be forced to depend on methods they don’t use> Break large interfaces into smaller, focused ones so classes only implement what they need, keeping code cleaner, easier to maintain, and more flexible

Day 3 of SOLID princple: Liskov Substitution Principle (LSP) is about ensuring that subclasses or subtypes can replace their parent class without breaking the program’s behavior.

Imagine to tearing Facebook down, because you want to add a new feature. #solid #oop #js

Day 2 of "SOLID" with the Open/Closed Principle (OCP): The OCP states that software entities (classes, modules, functions, etc.) should be open for extension but closed for modification. This means you should be able to add new functionality without changing existing code.

Clearer for teammates: No guessing what the code does. Single responsibility isn’t about perfect code. it’s about predictable code. When something breaks, you know where to look. When requirements change, you know what to modify.

Why SRP Matters for Sustainable Code: Easier to debug: Problem? You know exactly where to look. Simpler to test: One responsibility = one test focus. Safer to change: Modify one thing without breaking others. #js #node #solidprinciple

DAY 1 Today, we’re starting with "S" in SOLID: the Single Responsibility Principle. The rule is: Every function or class should have one reason to change. One clear responsibility. As it is said, “If you can’t explain what your function does in one sentence, you have a problem”
