Summary

Senior🎓
Top SchoolJanne Valtanen is a senior software developer with over a decade of hands-on experience building measurement, test automation and data analysis systems for RF, antenna and IoT domains. He blends applied mathematics (MSc) and signal-processing expertise with full‑stack software skills—Python, Django, React, SQL/NoSQL, Docker and embedded C/ARM—delivering tools that automate lab workflows and turn complex measurement data into actionable insights. Past roles span Nokia, Microsoft and Wirepas, where he developed low-level drivers, antenna measurement databases and gateway/APIs for wireless sensor networks. Currently at AFRY X, he applies GIS, PostgreSQL and cloud containers to smart-forestry problems while continuing to develop antenna test analysis software remotely. Colleagues rely on him for bridging mathematical rigor and pragmatic engineering—he’s equally comfortable optimizing interpolation on spherical surfaces and shipping RESTful services.
