At Umbrage, I lead full-stack development for a mission-critical software system in the oil industry. This platform monitors tank banks, pipelines, and control centers, proactively sending alerts for any detected issues. We designed it with robust workflows to manage material requests and internal validation processes, ensuring operational continuity.As a founding engineer on the project, I played a central role in architecting the system, setting up code and infrastructure foundations, and establishing industry-standard practices. Leveraging Next.js, Nest.js, and AWS for scalable deployment, I also implemented error monitoring through OpsLevel and supporting tools to maintain high availability and responsiveness.Our system processes over 5000 data points per second and has streamlined materials requests by 33%. I continually aim to deliver solutions that make complex workflows more manageable and actionable.

I founded Heaily, a mobile app designed to connect nurses with patients, and led its development for 5 months. I designed and developed the entire system architecture using React Native for the mobile app, AWS for hosting and scaling the application (achieving 99.9% uptime), and Node.js for the backend. I also integrated CircleCI for continuous integration, resulting in a 20% reduction in deployment time and minimizing downtime. In the second version of the app, I improved performance by nearly 30% through advanced techniques such as caching, offline mode, and creating custom features like voice recording. These enhancements led to a 40% increase in user engagement and a 25% reduction in load times, providing a smoother and more reliable user experience.
