Backend Engineer focused on building and operating scalable APIs, distributed systems, and the infrastructure that runs them.
I design and maintain production backend systems that handle real-world traffic, financial workflows, and multi-tenant architectures.
I also continuously refine my approach to system design, scalability, and distributed architecture through hands-on production experience.
My recent work spans:
- High-concurrency API systems (USSD + Web platforms)
- Event-driven and asynchronous processing pipelines
- Distributed services with strong data consistency guarantees
- CI/CD pipelines and cloud infrastructure across multiple environments
I’ve operated as the primary backend & DevOps engineer across multiple products, owning systems end-to-end, from architecture to deployment and production stability.
