Nathan B.

Senior Software Engineer & Architect with 20+ years of experience designing and delivering enterprise-level solutions across the full stack. Deeply proficient in both the .NET ecosystem (C#, ASP.NET Core, .NET Core) and the Java ecosystem (Java, Spring Boot, Spring MVC), as well as Node.js, Python, JavaScript, and TypeScript — with a proven track record of building scalable, high-performance systems for industries including fintech, retail analytics, and edtech.

On the backend, I architect robust APIs and microservices using ASP.NET Web API, Spring Boot, Node.js, and FastAPI, design efficient data pipelines, and manage complex databases across SQL and NoSQL platforms (SQL Server, PostgreSQL, MongoDB, DynamoDB, Cosmos DB). On the frontend, I build clean, maintainable UIs with React and TypeScript/JavaScript, and use Python for data analytics, automation, and AI integrations.

I'm an AI-native developer — I use Claude Code and Cursor daily to accelerate ticket throughput, reduce boilerplate, and ship faster. I have hands-on experience building LLM-powered applications using the Anthropic and OpenAI APIs — from prompt engineering and retrieval-augmented generation to integrating AI capabilities directly into production workflows. I can help your team adopt AI tooling, demonstrate what's possible, and get other developers up to speed quickly. I've also designed and implemented webhook-based automation pipelines that connect SaaS platforms, internal systems, and third-party services into cohesive, event-driven architectures. My cloud experience spans Azure and AWS, with a strong foundation in containerized deployments, infrastructure-as-code, and CI/CD automation.

I have a strong passion for troubleshooting complex systems and diagnosing hard-to-find bugs — from race conditions in distributed services to memory leaks in long-running processes. I bring a methodical, root-cause-focused approach to debugging that resolves issues quickly and prevents recurrence. On the performance side, I've consistently delivered measurable gains: optimizing SQL queries and caching strategies to cut response times by 40%, profiling and tuning Java, Node.js, and .NET services under heavy load, and redesigning bottlenecked architectures to handle millions of transactions daily.

I've led teams of up to 15 engineers, driven cloud-native transformations, and implemented DevOps practices with Docker, Kubernetes, Terraform, and CI/CD pipelines that cut release cycles by 50%. Whether greenfielding a new platform, modernizing a legacy system, or being called in to fix what others couldn't, I deliver reliable, well-tested code that scales with your business.
