I’m a full-stack Software Engineer with over five years of experience building scalable, high-impact applications across healthcare and global e-commerce platforms. My core expertise lies in React, TypeScript, and Node.js, where I’ve led end-to-end development of user-facing features and backend services in production environments. At Montu, I designed and implemented real-time, event-driven systems using Kafka and AWS, including a telehealth platform supporting video, voice, and chat, as well as patient-facing services that improved responsiveness and user experience. Previously at Expedia Group, I worked on large-scale systems using React, Node.js, and serverless AWS technologies to automate workflows, improve system reliability, and support high-traffic applications. What sets me apart is my ability to bridge front-end and back-end development with a strong focus on system design, performance, and real-world impact. I’m comfortable working in fast-paced, agile teams, contributing to architectural decisions, and taking ownership of features from concept to production. I value clean, maintainable code, strong collaboration, and building solutions that are not only technically sound but also aligned with business outcomes. I’m particularly motivated by opportunities where I can contribute to scalable platforms, work closely with small teams, and deliver meaningful improvements to user experience and system performance.
