Juha Wilppu

Engineering Manager

I lead engineering teams and still write code myself: React, Node.js, PostgreSQL and AWS. 14 years of shipping production systems, mostly in healthcare and finance.

I work from the first idea through to production: deciding what to build, making the trade-offs, shipping it, and keeping it running afterwards. I like simple solutions and will argue for them until the problem really needs something bigger.

Selected work

Provet patient portal

A new booking portal for vet clinics, built by the team I lead. Most clinics moved across from our older product, and it now takes 21,000+ bookings a week with a 4.6/5 rating from users. I set up the AWS infrastructure, CI/CD and monitoring, and still keep them running.

Nordhealth.fi

Built the AWS infrastructure and the authentication, and was responsible for the system's security and performance. In practice, a lot of what we built next was my call.
