About Me

As a Senior Frontend Engineer, I focus on building scalable, high-performance web applications that prioritize user experience. I enjoy crafting intuitive interfaces and optimizing performance, ensuring that every interaction feels smooth and responsive. My expertise lies in building scalable React components and maintaining clean, maintainable code that grows with the product.

I take a product-first approach, balancing technical decisions with business impact. I enjoy collaborating with designers, backend engineers, and stakeholders to bring ideas to life and create seamless user experiences. Beyond building great products, I’m always looking for ways to improve frontend best practices and streamline development workflows to make engineering more efficient and enjoyable.

Looking forward to new opportunities and exciting challenges!

Experience

  1. July 2020 - January 2025

    At RapidSOS, I played a key role in shaping frontend architecture, real-time systems, and geospatial solutions to enhance emergency response technology. I helped build a reusable React component library to standardize UI development, refined state management with Redux Toolkit, and modernized testing frameworks. I also engineered real-time messaging and alert systems using WebSockets and TalkJS to improve emergency response times. Additionally, I integrated interactive geospatial visualizations with Google Maps, Esri Maps, and DeckGL, enabling live incident tracking.
