WHAT I ENJOY WORKING ON

Backend APIsDistributed systemsEvent-driven designCloud-native deliveryContinuous learning

01 / ABOUT

Good engineering starts
with good fundamentals.

I like understanding how systems behave—not just how to make them run.

From a clean REST endpoint to an event-driven workflow, I enjoy making complex backend requirements easier to understand and maintain.

My focus is backend application development: API design, service integration, data access, caching, messaging, performance, and the engineering practices that make software easier to ship and operate. I also use personal repositories to practise and document topics such as Kubernetes, Kafka, Spring Boot, and data structures and algorithms.

See what I'm building ↗

Keep it understandable

Clear contracts, readable code, and simple designs before unnecessary complexity.

Build for real conditions

Think about failures, retries, observability, tests, and how a service behaves in production.

Learn by shipping

Separate repositories for focused learning, experiments, and end-to-end project work.
