I work with financial data providers and with teams that use third-party data.
For providers, I build the SDKs and APIs customers use to get your data, and I check from outside, with a customer’s access, whether your API delivers what it should. For teams consuming data, I build integrations that bring it into your applications and pipelines that keep it in your storage. Those can be separate projects or one after the other.
Each project has a fixed scope and ends with a handover. Maintenance afterward is optional.
