At Mindjoy, I architect end-to-end RAG workflows connecting Next.js interfaces to FastAPI microservices for multimodal document processing and conversational agents. I also built a WebSocket and server-sent events pipeline that reduced perceived user latency by over 60%.

At Kodamai, I led the decoupling of a Django monolith into containerized microservices on AWS ECS and designed event-driven ingestion pipelines. I also developed Hugging Face classification models to route incoming customer-support tickets.

At PangiaPass, I designed reusable Vue.js interface components and built Python and Flask endpoints for media workflows. My projects include DocumenSo, an electronic-signature platform, and SuperTokens, an identity-management backend.
