Most companies reach me at one of three moments: they are building a connected product and need architecture that will scale; they have a prototype and are not sure how to reach production; or they are at a technical decision point and want someone who has been there before.

I work across the full stack: embedded firmware, cloud backends on AWS, iOS and Android mobile apps, APIs, security, and AI / LLM agentic development. The open source connectivity software I created runs in billions of IoT devices worldwide. I have designed and shipped these systems with small teams under real constraints, for clients including ABB, Electrolux, Husqvarna, tado, and LiFX, across more than 30 products. For 12 years I ran Thingsquare as CEO. I understand both the technical and the business side of what my clients are building, and I know what it takes to turn a technical idea into a good business.

I take on a small number of engagements. If you are working on a hard technical problem and want a fractional CTO or senior technical partner who has shipped it before, write to me at adam@dunkels.com.
