RAG pipelines over 83,000 documents. ML that retrains itself from live feedback. Agents that debug their own code. Based in Phoenix, AZ, graduating May 2026.

I started with a B.Tech in Biotechnology, a discipline that trained me to think in systems, run controlled experiments, and never trust a result without stress-testing it. That instinct transferred directly into software engineering.

"If you cannot explain the data pipeline end-to-end, you do not own the model."

At 4 Systems Info Solutions I spent over two years building at real scale. Spring Boot APIs processing millions of records, database schemas tuned to cut query latency by 40%, and CI/CD pipelines that reduced release windows by 60%. Real systems, real traffic, real accountability.

Now at Arizona State University (GPA 4.0), I have gone deeper into intelligence: embedding 83,000+ FDA documents for RAG retrieval, architecting a 7-service ML pipeline that retrains from live user feedback, and writing a LangGraph agent that detects, diagnoses, and patches its own bugs.

I also taught 150+ students Java as an Instructional Assistant. The clearest proof you understand something is your ability to explain it clearly to someone who does not.

Currently building

Mnemo, an AI assistant solving three production GenAI problems at once: persistent memory across sessions, RAG document grounding so it stays factual, and confidence-scored hallucination detection. Stack: LangGraph, Claude API, ChromaDB, PostgreSQL.
