Juha Wilppu
Engineering Manager & Software Architect
I'm a Finnish engineering leader with 13+ years of experience in software development. I work across backend, frontend, and cloud infrastructure. I build reliable systems, mentor developers, and get things shipped.
I don’t just write code — I help teams make better decisions. I know what to build, what to avoid, and when to keep things simple.
Current focus: React, Node.js, PostgreSQL, and AWS.
Side project: Siikli.fi – a simple ERP for agriculture.
