Summary
Marc Lewandowski is a Lead Software Engineer with deep C# and SQL expertise and 24 years of experience designing resilient back-end systems, APIs, and cloud-native services on AWS. He repeatedly lifts struggling teams through hands-on technical leadership—mentoring, rigorous code reviews, and pragmatic architecture choices that translate into measurable stability and developer productivity. Marc has modernized legacy systems into unified C# REST APIs, built customer-facing portals that became sales enablers, and designed SQL-backed queueing for zero-downtime feature rollouts. Comfortable across the stack, he blends API-first microservice design, Terraform-driven infra, and UI work (React/ASP.NET Core) to reduce operational overhead. Notably, he brings domain experience in tax-rating and billing systems, turning complex regulatory logic into reliable, auditable software. Based in Rochester, NY, he’s open to onsite, hybrid, or remote roles where a cohesive technical vision and team elevation are needed.
