What I'm looking for

I am looking for a role that challenges me technically and fosters innovation.

As a Staff Software Engineer with over 9 years of experience, I have a proven track record of leading the development of innovative software solutions that enhance user experiences and drive business success. At Twilio, I spearheaded the creation of a HIPAA-compliant telemedicine platform that leveraged AI technology to significantly reduce patient intake times by 40%. My expertise in architecting microservices-based backends and implementing real-time event-driven features has consistently improved system responsiveness and scalability.

Prior to my role at Twilio, I served as a Senior Software Engineer at Roofstock, where I developed a scalable property listing platform that streamlined the listing process for property owners, resulting in a 30% reduction in manual efforts. My commitment to optimizing CI/CD pipelines and enhancing real-time capabilities has led to improved customer satisfaction and increased revenue for the businesses I have worked with. I am passionate about leveraging technology to solve complex problems and deliver impactful solutions.
