What I'm looking for

I am looking for a collaborative environment that values innovation and growth.

I am a Senior Software Engineer with over 6 years of experience in designing and building scalable web and microservice solutions. My journey has taken me through various roles, where I have honed my skills in .NET, AWS, and React. I am passionate about Domain Driven Design and Event Sourced systems, which has allowed me to contribute significantly to the projects I have worked on.

At QSX Software, I designed and maintained a $60M self-storage management platform, developing a suite of 22 .NET microservices on AWS. My efforts improved system throughput by 80% through Redis caching and I actively supported over 200 self-storage facilities. I take pride in my ability to lead and mentor junior developers, fostering a collaborative and adaptable team environment.

Previously, I worked as a Full Stack Engineer at Foursquare, where I maintained and improved a geospatial analytics platform using React and NodeJS. My contributions included developing over 50 components and enhancing the UI/UX. I also have experience in data exploration and ETL operations, which has equipped me with a diverse skill set to tackle various challenges in software development.
