APIs every Nigerian fintech developer should understand: → NIBSS NIP — interbank instant transfers → CBN RTGS — high-value settlement rail → NIBSS BVN validation — identity verification → Paystack / Flutterwave — payment infrastructure + collection → Smile Identity — KYC (ID + selfie verification) → Dojah — BVN, NIN, CAC & identity APIs → Mono — open banking / bank data access → Stitch — cross-border payment infrastructure (SA focus) → VGS (Very Good Security) — PCI vaulting & card data security I know most of you know the top 2. The ones building serious infrastructure know all of them. Save this.

You will be a world-class backend engineer once you finish watching all these courses:

Stop paying for native haptic apis use this web library instead

As a developer , what do you build first of a website ?

Does “WhatsApp” use WebSockets or gRPC? Short answer: No. What WhatsApp uses WhatsApp uses a custom messaging protocol built on top of MQTT over TCP/TLS. What is MQTT? MQTT (Message Queuing Telemetry Transport) is a lightweight publish–subscribe messaging protocol designed for: •Low bandwidth networks •High latency or unreliable connections •Devices that need to stay connected with minimal battery usage It was originally built for IoT, but its design fits mobile messaging extremely well. How it works (high level) •Each device maintains a persistent TCP connection to WhatsApp servers •Messages are sent as binary payloads (not JSON) •Uses acknowledgements to guarantee delivery •Automatically recovers from network drops •TLS is used for transport security (along with end-to-end encryption) Why not WebSockets? •Extra overhead for mobile networks •Less battery-efficient at WhatsApp scale •Not designed for intermittent connectivity Why not gRPC? •Best suited for backend microservices •Not optimized for billions of client connections •Browsers and mobile apps aren’t its primary target TL;DR •Browser apps → WebSockets •Backend microservices → gRPC •Massive mobile chat apps → Custom TCP + MQTT-style protocols That’s how WhatsApp stays fast, reliable, and battery-friendly at scale.
