Final-year BSc Computer Science @ University of Johannesburg
Johannesburg, South Africa
Building encrypted data pipelines, federated ML systems, and event-driven backend platforms.
Interests: cryptographic design, distributed consensus, zero-trust architectures
Currently reading: Designing Data-Intensive Applications (Kleppmann) & Understanding Distributed Systems (Vitillo)
Seeking backend engineering roles focused on distributed systems,
secure infrastructure, and large-scale platform architecture.

I spend time with photography, art history, and classical music. I enjoy architecture photography, chiaroscuro paintings, and long evenings with Bach’s cello suites.
Poetry and too much tea are permanent fixtures.
