Message

At Wissen Digital, I contribute to the architecture and implementation of Diligent Vault, an enterprise ethics and compliance platform. I work across React, Node.js, TypeScript, and AWS AppSync GraphQL APIs, with a focus on secure access and production reliability.

Across healthcare and digital learning platforms, including Labcorp and the Aastrika/Sunbird ecosystem, I developed backend and full-stack capabilities, APIs, and microservices. I also apply LLM and RAG patterns such as embeddings and semantic search, connecting retrieval workflows with application APIs and enterprise security.
