What I'm looking for

I am looking for a role that fosters innovation, collaboration, and growth in AI and software development.

I am a Senior Software Engineer with extensive experience in backend development, particularly in AI-driven applications. At Amazon, I led the development of clinical voice-to-note tools, utilizing Python and Go to create secure, real-time data pipelines. My work involved designing audio streaming pipelines and building an AI-powered voice agent that enhances doctor-patient interactions through real-time transcription and structured summaries.

Previously, at Walmart, I contributed to the e-commerce backend, impacting over 100 million users globally. I focused on performance optimization and developed a dynamic frontend using React and Redux, improving user experience for healthcare professionals. My passion for mentoring junior engineers and leading cross-functional teams has been a key part of my career, ensuring best practices and innovative solutions are implemented across projects.
