What I'm looking for

I'm open to remote roles with US companies.

At 10 Pearls, I maintain and evolve Cohere Health’s healthcare platform, supporting clinical workflows, prior authorizations, and payments. I contributed to care policy authoring and clinical review tools, and implemented AI-driven retrieval to support natural-language decision-making.

At GFT Technologies, I worked on the risk squad for a FX clearing and settlement platform for B3, building microservices and event-driven integrations for distributed risk calculations. I also maintained Go APIs that reduced response times by about 30% compared with the original implementation.

Earlier, I contributed to Santander’s Open Finance APIs at Accenture and built healthcare integrations using the TISS standard at Athena Health. My work spans healthcare and financial services, including cloud-native systems, platform integrations, and my own event-driven ERP and media orchestration projects.
