Two developers building ethical and sustainable tech solutions - one line of code at a time.

Who We Are

Two developers on a mission

We're a duo of passionate technologists who believe code can—and should—make a difference. We build tools for observability, help companies understand their data, and champion the idea that technology doesn't have to come at the expense of our planet or our values.

When we're not coding, you'll find us on mountain trails, exploring nature and reminding ourselves why sustainable tech matters. We take security and privacy seriously—not as buzzwords, but as foundational principles woven into everything we create.

Open Source First

We believe in sharing knowledge and building in public

Green & Ethical

Sustainability and ethics aren't optional - they're core to who we are

Nature Lovers

Hikers and outdoor enthusiasts who code with purpose

🌱 Fun fact: We're both vegans and avid hikers. Our best ideas often come during long trail walks, and we're committed to keeping our code as clean as the environments we love to explore.
