Aymen Krifa

About

Machine Learning Engineer with 4 years shipping production GenAI and ML systems at scale. Mostly builds things — AI systems at work, dev tools on the side, and the occasional side project that outgrows its weekend. Off the clock, usually reading, tinkering, or chasing a new rabbit hole.

If you're building something interesting, I'm always up for a good conversation. Let's talk →

    Selected Projects

    Personal and open-source projects.

    AutoActivator

    Automatically activates the right Python virtual environment when you enter a project and deactivates it when you leave — no more tracking which one is active as you move between projects; it just handles it, near-instantly (See benchmarks →)

    Shell
    Reaper

    A Rust TUI for browsing and killing listening ports, built after one too many times forgetting the right lsof flags — and also an excuse to explore Rust.

    KExplorer

    Everything Lens and k9s spread across multiple views, in a single highly opinionated web-based Kubernetes dashboard — with pod grouping by project on top.

    Chroma Explorer

    Forked to keep working against Chroma 0.x servers when 1.x migration was not an option. Rewinds the JavaScript client to the legacy /api/v1 API while keeping the full GUI.
