What I'm looking for

I'm seeking an AI or Software Engineering role where I can build practical automation tools, backend services, and user-facing AI products.

I've built multi-agent lead intelligence workflows and knowledge-retrieval products using Python, CrewAI, LangChain, Groq, Gemini, OpenAI, and DeepSeek APIs.

For Agency Hunter PRO, I created a CrewAI and Groq Llama 3 pipeline that turns public company signals into prospect briefs, pain-point hypotheses, outreach angles, and repeatable Markdown/CSV research reports. I designed researcher, analyst, copywriter, and reviewer agents with reusable prompts and human-review checkpoints.

During the Codex Community Hackathon, I owned Python backend ingestion and processing for a knowledge-retrieval MVP built by a four-person team in 48 hours. I normalized signals from Discord, Slack, Notion, and GitHub, then orchestrated AI workflows that surfaced evidence and concise explanations through a React frontend.

I'm an Artificial Intelligence undergraduate focused on LLM applications, multi-agent systems, business automation, backend services, and user-facing AI products. I've also developed React features and REST API integrations for an online reading platform and co-designed AI conversation flows for an anonymous mental health platform.
