Summary
👤
Senior🎓
Top SchoolRobert Casto is a Senior Software Architect with 11+ years of hands-on experience building scalable Java/Spring backends and cloud solutions, currently focusing on cloud architecture at Northrop Grumman. He has a strong track record in performance tuning and debugging—having delivered 40x speedups on Monte Carlo simulations and cut multi-hour batch jobs down to minutes—plus deep AWS migration experience moving dozens of Grails/Tomcat apps to ECS. Comfortable leading teams or running solo, he has mentored junior developers, led multiple vertical projects for military and eCommerce clients, and built customer-facing services that isolate heavy processing from main sites. He pairs pragmatic full-stack skills (Java, Groovy, Grails, MySQL, Redis, Docker, AWS) with operational awareness from roles at Exiger, Amazon, and consulting firms. Based in Ohio, he thrives in remote environments, is open to client-facing work and infrequent travel, and uniquely combines enterprise-grade architecture experience with founder-level product ownership from his years running SellersToolbox.com.
