At Apium.io, I architect and develop Maash, a P2P transaction platform, using Python and FastAPI microservices with a React and Redux frontend. I also built a financial data platform with REST endpoints and Redis-cached visualizations.

Earlier at Apium.io, I developed data ingestion and query workflows and implemented a version-controlled data lake on LakeFS over S3. I also built projects including VideoVault, a cloud-native video streaming platform, and SupplyGuard, a Rust daemon for detecting supply chain attacks.
