What I'm looking for

I am looking for a challenging role that fosters innovation, collaboration, and professional growth.

I am a results-oriented Software Engineer with over 10 years of full-stack experience, specializing in building scalable web platforms using React and C# .NET. My career has been marked by significant achievements, including improving system performance by up to 35% and accelerating development cycles by 20% through the implementation of microservices and modern UI frameworks. I have made a proven impact across high-traffic platforms at leading companies such as Instacart, Eversight, Capital One, and CME Group.

At Instacart, I developed React-based interfaces that improved user task flow completion rates by 28% and rewrote legacy APIs into modular microservices, enhancing reliability under high load. My role involved mentoring junior engineers and participating in system observability revamps, which cut incident response times in half. I thrive in collaborative environments where I can partner with design and data teams to implement A/B tested UI improvements that drive conversion rates.

Throughout my career, I have consistently focused on enhancing user experiences and optimizing backend processes. I have led efforts to integrate advanced technologies such as GraphQL, SignalR, and Redis caching, significantly improving application performance and user engagement. My commitment to continuous learning and improvement drives me to stay updated with industry trends and best practices, ensuring I deliver high-quality solutions that meet both technical and business needs.
