At Self-employed, I built an AI-enabled SaaS platform that connects Laravel with FastAPI services for LLM and MCP processing. I created a PostgreSQL pgvector RAG pipeline orchestrated with LangGraph and connected four LLM providers through one abstraction layer.

I also maintained a production multi-tenant alumni SaaS, including CDN storage integration and custom development for client organizations. Earlier, at Konnekt Hub, I led the architectural design and development lifecycle of a multi-tenant Alumni Management SaaS.
