9 hackathon wins since 2025Senior developerJonathanSolvesProblems on YouTube

I'm Jonathan Andrei, a senior software developer in Canada. I build AI-integrated products, full-stack web apps and React Native mobile apps for founders and teams worldwide. I spent two years at Cirque du Soleil rolling out ServiceNow and a year at IBM managing Watson AIOps integrations, and I now deliver ServiceNow and AI work through N2 Help & Solutions for clients such as Hydro-Québec. Since 2025 I've won nine hackathons, with prizes from OpenAI, UiPath, DataHub, CockroachDB × AWS, Google AI and Sentry.

What I bring to a project

Four things I've stayed true to across seven years of shipping. Tap any card for the story behind it.

01

I don't give up on hard problems

I stay with a problem until it's actually solved, not until it's mostly working. The boring middle, the retry logic, the migration script nobody wants to write, that's where the real work lives.

Two years at Cirque du Soleil rolling out ServiceNow was mostly workflow mapping before a single script got written. Same story at IBM writing the translation table nobody else wanted to. That's the middle nobody puts in a demo, and it's what makes the demo hold up in production.

AI produces code that runs. I produce code that survives contact with your customers.
