Top SchoolJohn D'Ambrosio is an owner and seasoned software engineer and architect with 11+ years of experience building scalable, distributed web applications and guiding teams through cloud-native transformations. He has led migrations from monoliths to microservices and containerized Kubernetes deployments, instituted CI/CD and DevSecOps practices, and rearchitected systems to measurably improve reliability and performance. Comfortable wearing product, engineering, and architecture hats, he has driven product recoveries, modernized data enrichment and messaging pipelines, and mentored engineers in agile value-stream planning. His background includes high-stakes technical leadership in the Navy and the DoD, where he designed instrumentation and secure data platforms for complex operational environments—experience that informs his pragmatic, security-conscious approach to enterprise systems. Based in Washington, D.C., he combines hands-on coding (Python, Django, React, Typescript, Postgres, Elasticsearch) with systems-level thinking to help small teams move fast without sacrificing long-term maintainability.
