I am a Senior Software Developer Team Lead at Quext, a company that provides chatbot solutions for the multifamily industry. I have over five years of experience in the entire product development cycle, from ideation and planning to design, implementation, and maintenance.

My passion is to bring conversational AI to life, using cutting-edge technologies such as vector embeddings, semantic search, GPT LLM, and Dialogflow. I have led and contributed to several successful projects that have enhanced the company's chatbot product, generated positive feedback from clients and users, and created new business opportunities. I have also designed and developed REST APIs, relational databases, and front-end applications using various frameworks and tools.

I hold a Bachelor's degree in Computer Science from The University of Texas at El Paso, where I graduated in 2018. I also won first place in the Parkhub Challenge, a hackathon that required creating a solution to predict future traffic conditions using historical and public event data.

As a team leader, I am adept at bringing fresh ideas to the table and communicating effectively with both technical and non-technical managers. I value collaboration, innovation, and quality, and I strive to deliver solutions that meet and exceed the expectations of the stakeholders and the end-users.
