[email protected]

I'm a Staff-level Full Stack Software Engineer with over 12 years of experience building secure, scalable, and high-performance applications across enterprise, cloud, and consumer-facing domains. With a Master’s degree in Computer Science from Texas Tech University, I specialize in designing resilient architectures, leading cross-functional teams, and delivering software that’s elegant, efficient, and built to last. My expertise spans modern frontend and backend technologies—React, TypeScript, Node.js, and cloud-native services on AWS. I’m passionate about developer experience, performance optimization, and creating systems that are as maintainable as they are powerful. I’ve also led initiatives around accessibility, CI/CD, and mentoring engineers to grow and ship with confidence. In addition to my core engineering work, I consult and collaborate on freelance projects—helping teams architect and deliver robust software solutions.

Interests

Outside of software engineering, I enjoy spending time outdoors—whether it’s hiking, kayaking, or just staying active. I love to travel, explore new places, try different cuisines, and learn about diverse cultures. I'm an avid follower of movies, TV shows, and sports—cricket being my favorite. I’m also an aspiring home chef who enjoys experimenting in the kitchen. Passionate about continuous learning, I stay up to date with the latest in tech, regularly explore new tools and frameworks, and enjoy attending conferences and tech meetups to stay connected with the community.
