Work History
Team Leader Intern
Motorola Solutions
Richardson, Texas
08.2025 - 01.2026
- Main components of the project include the data ingestion and retrieval pipeline. Used public test data, which can be used for Motorola's private internal documents.
- Developed internal RAG evaluation dashboard to benchmark and visualize retrieval-augmented generation pipelines.
- Enabled engineering teams to assess retrieval quality, context grounding, and hallucination risk.
- Integrated embedding models via SentenceTransformers for encoding document chunks into vector representations.
- Implemented cosine similarity for matching queries to top-k relevant chunks for LLM processing.
- Established metrics for diagnosing failure modes in RAG systems, including faithfulness and relevance.
- Computed token-level metrics to evaluate context utilization within answers effectively.
- Supported diverse applications such as internal knowledge search and engineering documentation retrieval.
- Finally, presented the product to company mentor and faculty advisor for approval.
Motorola MCP
Motorola Solutions
Richardson, Texas
08.2025 - 01.2026
- MCP Context Assembly: an MCP server (SDK-based) + client that (a) proves protocol mastery via bare-metal JSON-RPC, (b) exposes tools/resources/prompts, and (c) builds session-aware memory_context bundles with token budgeting for stateful conversations.
- Provided support and guidance to colleagues to maintain a collaborative work environment.
- Conducted comprehensive research and data analysis to support strategic planning and informed decision-making.
Student Intern

Projects:
- AI Agent Development Framework (Google Cloud + ADK) - Built and deployed modular AI agents using Google AI Studio API and Agent Development Kit (ADK), integrating secure API key management and cloud-based project configuration. Implemented multiple agent architectures including basic conversational agents, tool-augmented agents, multi-agent orchestration, and stateful session-based systems which was used in my experience for Motorola Solutions
- Developed structured output pipelines using Pydantic schemas to ensure consistent model responses, implemented persistent storage for cross-session memory, and designed sequential and parallel agent workflows for improved performance. Leveraged LiteLLM for flexible model abstraction and callbacks for real-time monitoring of agent behaviors.
- Demonstrated advanced agent patterns including multi-agent collaboration, iterative loop refinement, and stateful task orchestration for scalable AI application development.
- Alexa Skill, AWS Lambda, Amazon Polly, Used lambda functions with AWS Serverless Application Repository, Deployed Alexa skill to Lambda and created custom Mp3 audio source
