## About

```text
At enter ai: Agent Suite, I architected a multi-tenant platform for configuring, running, and monitoring AI agents. I built its execution layer for document processing, retrieval, tool calls, and model orchestration.

At xAnalytica, I built an LLM-powered data analysis MVP that turns users’ data into charts and answers natural-language questions. At Epic Listing, I built AI image-editing features and asynchronous bulk processing for a real estate platform.

Across products including SerpNest and Feedwell/ Feedmate, I’ve built full-stack SaaS features spanning analytics, scheduled workflows, real-time updates, and role-based permissions. My work ranges from contributing to existing systems to planning and building products from scratch.
