Building reliable systems, one layer of abstraction at a time.

I'm a Backend-focused Software Engineering graduate (First Class Honours, 4.65 CGPA) from Novena University, Nigeria. I currently work as a Rust Code Reviewer at Turing, reviewing production-quality async Rust code daily.

My focus is on building backend systems that are correct first, fast second, understanding the internals before reaching for abstractions. I spend a lot of time in Rust, exploring async runtimes, type-driven design, and systems-level patterns.

A CLI contact manager evolving into a full Cargo workspace with separate cli, api, and libs crates. Highlights:

• Async HTTP layer built with Axum + Tokio
• Multiple storage backends (JSON, CSV, SQL, TXT, remote HTTP) behind a unified ContactStore trait
• OS-level file locking via fs2 for safe concurrent writes
• Type-safe error handling with thiserror / anyhow

This project is a practical study of how Rust's ownership model and trait system shape real API design.

A Flask-based URL shortener with fast redirects and a clean REST interface.

A Node.js/Express REST API for credit and debt management between users, backed by SQL.

• Axum internals: extractors, middleware, shared application state with Arc<T>
• Async Rust: futures, task scheduling, tokio::select!, channels, and Pin<T>
• Backend architecture patterns: layered services, repository pattern, error propagation strategies
• System design: scalability tradeoffs, database indexing, caching layers

• Backend engineering internships and junior roles (on-site, hybrid, or remote)
• Open-source collaboration on Rust projects
• Roles involving API design, systems programming, or developer tooling
