Hello developers!
This is a demo of an app that I was working on.
Language: Java
Database: Firebase

Thanks @DBihako for the contribution.

Testing Rate Limiting with Resilience4j and JMeter taught me one thing: controlling request flow keeps APIs reliable and prevents overload. Simple, but game-changing. @ApacheJMeter @springboot @java

Built a modular microservice platform combining Job, Company, and Review services using Spring Boot, PostgreSQL, and Docker. Each service manages its own data but communicates via APIs.

C’est simple.
C’est sans frais.
C’est Shwary.
L’argent bouge vite. Comme un message.

Diving into React hooks: useState, useEffect, useRef, useContext, useCallback, useReducer.

I made a small repo with practical examples showing how and when to use them.

Building a Secure Auth Service with API Gateway, Postgres, Kafka & gRPC in Spring Boot

🌀 Kafka Producer vs Consumer:

Producer ➡️ Sends data to Kafka topics
Consumer ⬅️ Reads data from Kafka topics
Producer: Pushes events 🔼

Consumer: Pulls messages 🔽

Both use serializers (out/in)

Publish. Subscribe. Scale. 🚀

[MM_dev @MasuJoe]

Kafka vs gRPC

Kafka = async, event-driven, high-throughput
gRPC = sync (or async), low-latency, point-to-point RPC

Kafka for streaming data, gRPC for real-time service-to-service calls.
Choose based on communication pattern, not hype.

#DevOps #Microservices

[MM_dev @MasuJoe]

🚀 Why choose gRPC over REST?

✅ Faster (binary over HTTP/2)

✅ Strongly typed with Protobuf

✅ Bi-directional streaming

✅ Built-in code generation

✅ Ideal for microservices & real-time apps

gRPC isn’t just faster—it’s smarter. ⚡💡

⚡️Spring Boot dev tip:
Need a fast, throwaway database? Use H2 in-memory!
Just plug in: jdbc:h2:mem:testdb 🧪
🚨 But heads up:
Your data self-destructs on restart 💣
→ Add data.sql to preload it every time.

@GalienMuhindo @QueryLens Can't wait to see this working at biggest international airports and borders.

Introducing @QueryLens – your AI-powered video surveillance co-pilot.
QueryLens monitors and searches video footage using your text descriptions.
No pre-defined parameters, no limits.

[MM_dev @MasuJoe]

🚀 In Spring:

@Autowired injects dependencies

@Primary marks a default bean when multiple exist

@Qualifier lets you pick the exact bean when there's a tie

Use @Primary for defaults, @Qualifier for precision! ⚙️

Networking at top tech events is broken.
You’re surrounded by brilliant people/ opportunities but don’t know who to talk to, or what intros to ask for.
That’s why we built Necta, your AI-powered networking assistant.
