About
Hi there! I’m Aleksis Jonas Lesieur, a full-stack developer specializing in data-driven web apps, cloud infrastructure, and scalable backend services. Over the past 8+ years, I’ve built end-to-end platforms using Rust, Python, Node.js, React, and Next.js, focusing on performance, reliability, and observability.
I love turning big datasets into actionable insights—ETL pipelines, ML-driven features, and tooling that helps teams work faster. I enjoy collaboration across frontend, backend, and data engineering, and I’m always learning new technologies to ship productive, maintainable software.
