I built and deployed MAK-AI v2, a full-stack AI assistant platform using React.js and FastAPI. It includes workspaces, chat history, document uploads, streaming AI responses, and RESTful APIs.

For MAK-AI v2, I developed LangGraph-powered agents with RAG, vector embeddings, document retrieval, and conversation memory. I also created n8n workflow automation that lets users generate and execute business workflows from natural-language prompts.

At Accenture, I provided production support and executed database change requests in Snowflake. I also monitored and troubleshot Snowflake and DynamoDB issues.

At WeServ(Fujitsu Philippines), I developed and maintained a SharePoint portal for Learning & Development and automated Project Management reporting. During my project assignment at Fujitsu Limited (Japan), I developed and tested a shell-script file transfer solution for a banking client on Solaris OS.
