Hello, I'm Lewis Wamocha.
I'm a Software Engineer
& System Architect

I design and build secure, scalable, and high-performance systems using Java and Spring Boot for robust backend services, microservices architecture for distributed systems, RESTful APIs, asynchronous messaging with Kafka and RabbitMQ, database modeling with MySQL/PostgreSQL/MongoDB, and full-stack integration using Angular, and React. I specialize in creating clean, maintainable architectures, implementing event-driven and real-time systems, and automating CI/CD pipelines for production-ready deployments. Passionate about leveraging AI, cloud-native platforms, and intelligent system design, I transform complex requirements into future-ready software that scales and delivers measurable impact.

About me

I’m a versatile software engineer with 3+ years of experience designing and delivering secure, scalable, and high-performance applications across complex enterprise environments. I specialize in building full-stack systems with Java, Spring Boot, Angular, and React, creating robust backend architectures, intuitive UIs, and real-time features that scale.

Beyond coding, I focus on system design, microservices, event-driven architecture, and cloud-native deployments. I have hands-on experience implementing CI/CD pipelines, containerized environments with Docker, and reliable asynchronous messaging using RabbitMQ and Kafka — ensuring resilience, observability, and performance in distributed systems.

I’m passionate about AI-enhanced solutions, DevOps automation, and intelligent system architecture, continuously exploring ways to make software smarter, faster, and more reliable. My goal is to bridge full-stack engineering, cloud infrastructure, and emerging technologies to build future-ready systems that deliver real impact.
