What I'm looking for

I’m looking to build secure, scalable APIs and microservices, optimize performance, and collaborate across teams with clean code, strong testing, and cloud deployments—where I can grow impact through ownership and continuous improvement.

I’m a Senior Backend Engineer with more than 7 years of experience leading website and backend design projects—from gathering user requirements and producing code to creating mockups and enhancing designs. I focus on clean, robust code and exceptional security, while consistently achieving compatibility targets and meeting customer demands.

In my current role at Virtusize, I design and build microservices architecture, optimize back-end performance, integrate third-party APIs, and deploy distributed systems on AWS. I also lead with quality by performing thorough code reviews, improving code quality with automated testing, and maintaining detailed documentation, drawing on earlier team leadership at Media Meter to train engineers and deliver high-impact features.
