I build scalable backend systems, APIs, and infrastructure with a focus on performance, reliability, and clean architecture.
I'm a Senior Backend Engineer focused on building production systems that handle real world traffic, distributed workloads, and evolving requirements.
My primary ecosystem is Python, with experience across backend frameworks, databases, messaging systems, caching, containers, cloud infrastructure, and CI/CD.
I also build full stack applications when needed using React, Next.js, Node.js, and TypeScript.
- Build high performance REST APIs and backend services
- Design distributed and event driven systems
- Develop microservices and asynchronous workloads
- Design and optimize relational and NoSQL databases
- Build caching and messaging architectures
- Work with MQTT based systems and IoT infrastructure
- Containerize and deploy production applications
- Build CI/CD pipelines and deployment automation
- Work with AWS and Google Cloud infrastructure
- Design API gateway and reverse proxy architectures
- Build full stack applications and SaaS products
- Develop developer tools and open source software
- Integrate AI and LLM capabilities into applications

I've worked on backend systems supporting 500K+ devices across multiple African markets.
One of the systems I worked on evolved from a synchronous implementation with multi second response times into an asynchronous architecture using:
