Player profile
Constantin
Hi, I'm Constantin! I'm a Partner Solutions Engineer at numo, and before that I did the same job at Google.
My job is building bridges. I work side by side with partners to design, build and launch integrations, translating between what a partner needs and what the platform can do, and sweating the details until it just works.
Earlier in my career I spent years shipping native Android and iOS apps and full-stack web apps. I've been the developer on the other side of the API, so I know where the rough edges are and how to get past them.

In progress
Goal: help partners get from “how does this work?” to a launched, healthy integration.
- Scope it. Understand what a partner is trying to build and map it to the right technical approach.
- Build it. Guide architecture and integration work from the first API call to launch day.
- Unblock it. Dig into the tricky bugs, edge cases and “works on my machine” moments.
- Level it up. Create demos, sample code and docs, and bring partner feedback back to product teams.
Reward Happy partners and integrations that just work.
