Florian Mierzejewski

Florian Mierzejewski is a Staff Engineer at Qonto.

Software engineer with 10+ YoE and a strong mobile background. I’ve worked in agencies and startups for widely different clients from various countries, on an even wider range of projects. From greenfield to enormous untested legacy codebases, I’ve seen horror and glory while repeatedly managing to have a positive impact. I aim to always write simple and readable code, apply best practices, share knowledge, pair program, and mentor with a good dose of empathy and compromises.
