With over 20 years of extensive experience in software development, a strong foundation in a variety of programming languages, and a proven track record in delivering efficient and scalable software solutions, I am confident in my ability to contribute effectively to your team. I specialize in full stack development, data engineering, database design, cloud migration, API integrations, and enterprise application modernization. My main technical strengths include .NET, C#, React, Angular, SQL Server, PostgreSQL, AWS, Azure, ETL, SSIS, Power BI, Tableau, Docker, Kubernetes, and microservices. Throughout my career, I have worked with healthcare, fintech, government, aviation, and enterprise clients. I have built web applications from the ground up, optimized slow systems, designed data warehouses, created ETL pipelines, developed reporting dashboards, migrated legacy systems to modern cloud platforms, and led development teams through full project lifecycles. I can help with: • Full stack web application development • NET / C# backend development • React / Angular frontend development • SQL Server / PostgreSQL database design • ETL, SSIS, data warehouse, and reporting • AWS / Azure cloud deployment and migration • API integrations and microservices • Power BI, Tableau, and Grafana dashboards • Legacy system modernization and performance optimization I am comfortable working independently or as part of a team, and I can take a project from requirements gathering and architecture through development, testing, deployment, and ongoing support. My goal is always to build solutions that are secure, scalable, reliable, and easy to maintain.

I've been a software architect and full-stack engineer for 20+ years, and I still write code every day. My professional background: 18 years as Technology Architect at Old Republic Home Protection, where I designed and built two enterprise platforms from greenfield. One was a microservices SOA system (Java/Spring Boot, Angular, RabbitMQ, SQL Server). The other was a cloud-first Azure platform (Docker, Azure Service Bus, Cosmos DB). I led a development team, ran CI/CD, introduced Security-by-Design and TDD, and was the person they called when projects went sideways. Before that: Senior Application Architect at MultiPlan in New York, building healthcare claims systems at scale (700+ users, 1.2M+ provider records). Since 2024, I've been building and running my own software products - several are live and in production: - Itty - A branded link-shortening SaaS with custom domains, click analytics, multi-user management, and Stripe billing. Built on Java 21 / Spring Boot 4 / Angular 21. - Klass Paperless - A digital template store for reMarkable tablets. Includes a headless-browser PDF generation pipeline, Stripe checkout, AWS S3 storage, and an Angular storefront. - Klass Video - A 4K AI video restoration and upscaling service. - Klass Wiki - A technical reference and blog I publish covering Spring Boot, SQL Server, Angular, Linux, and AI development. I also built my own AI agent infrastructure: a Spring AI MCP server that integrates email (IMAP/SMTP), git, CardDAV contacts, scheduling, and filesystem operations for Claude-based automation. What I work in: Backend: Java, Spring Boot (through v4), Grails/Groovy, REST APIs, microservices, Spring Security, JWT, OAuth 2.0 Frontend: Angular (v17-21), TypeScript, React, Next.js, Tauri (Angular + Rust for cross-platform desktop) Databases: SQL Server, SQLite, MySQL, Oracle (PL/SQL), Azure Cosmos DB, MongoDB Cloud: Azure (VMs, Spring Cloud, Service Bus, Containers, Cosmos DB, Blob Storage), AWS S3, Backblaze B2, Cloudflare R2 AI/LLM: Spring AI, Anthropic Claude API, Azure OpenAI (including Assistants API), MCP server implementation Integrations: Stripe, SendGrid, Okta/SAML, Telegram Bot API, Etsy, IVR/phone APIs, EDI Tools: Docker, Azure Pipelines, Gradle, Quartz Scheduler, Selenium/WebDriverManager, JUnit 5 I work across the full stack and adapt to what the project needs. I work independently without hand-holding, communicate clearly with non-technical stakeholders, and deliver. If you need someone who can take a spec and build it - or help think through what to build in the first place - I'd be glad to talk.
