I'M DENNIS PETER MUNYAO

My Coding Journey

🎯 My Engineering Journey

My passion for technology began in high school. Got into university, where I started coding with C++, and I discovered the power of logical problem-solving. This foundation led me to web development, where I quickly gravitated toward backend systems and scalable architecture.

Today, I specialize in building robust cloud-native applications and distributed systems. My expertise spans REACTJS, NEXTJS, ANGULARJS, NESTJS, PYTHON, and modern cloud platforms like GCP and AWS, with deep experience in:

  • System design
  • Microservices
  • Event-driven architectures

I've designed and implemented production-grade systems, including:

βœ… High-throughput message queue systems (RabbitMQ, Pub/Sub)
βœ… Scalable email campaign platforms handing multiple emails βœ… Real-time applications powered by WebSockets and event sourcing
βœ… Cloud-native microservices with container orchestration
βœ… API backends with authentication, rate limiting, and monitoring

I continually refine my skills in distributed systems, cloud infrastructure, and performance optimization. From designing YouTube-like video processing pipelines to enterprise-grade email systems, I thrive on solving complex scalability challenges.
