Benjamin Jesuiter

I'm a passionate programmer
who's been at home in web engineering for over a decade. From TypeScript and frontend work with Angular and SolidJS to CI/CD, cloud architecture, and senior-level consulting – I've worked across the full spectrum.

My current adventure is agentic engineering:
How do we harness AI while still building truly reliable systems? What do coding agents already grasp on their own and what do we still need to teach them? What will these developments mean for software engineering and society at large? And how do we approach them ethically and responsibly?

I love the energy of this moment
and can't wait for the many new people that I'll meet along the way!
