Hauser

I work across the stack: web products in Java / Spring and Angular, microservice architectures, Kubernetes infrastructure, prototypes, and I use AI every day in my development work.

About

Software engineer since 2016, with long experience of Java / Spring microservice architectures and Angular front ends (DecisionBrain, BPCE). Freelance since 2024 to multiply contexts: blockchain fintech, optimisation, generative AI. I look for contracts where I own a full product scope, from the data model to the interface.

Early 2026: six months spent experimenting with AI agents (MinecraftClaude) and on my homelab (NetWatch). I enjoy crossing layers: from prototype to production, from infrastructure to product.

Outside of code, I do bouldering and build furniture.
