💫 Hi! I'm Christopher - a Senior Full-Stack Developer & Engineering Lead (15+ yrs) who turns complex technical problems into clean, reliable software that runs quietly in the background, so your team can focus on growth instead of firefighting and technical debt. I've led full-stack development and modernization across government compliance, healthcare, SaaS, and enterprise operations. My deepest strength is the Microsoft stack - C#, .NET Core, ASP.NET Core, Web API, Entity Framework, SQL Server, and Azure - paired with modern front-end work in React, Vue.js, and Angular. I architect systems using microservices, CQRS, and Domain-Driven Design, secure them with OAuth and Azure AD B2C, and ship them through well-built CI/CD pipelines. I also stay current with AI-assisted engineering - GitHub Copilot, Claude Code, OpenAI/Azure OpenAI, and n8n agentic workflows - applying them to cut delivery time without sacrificing quality. What sets me apart: 👌 Senior-level judgment, not just code - architecture, modernization strategy, and engineering standards that hold up over time 👌 I specialize rather than scatter - deep .NET and cloud-native expertise, not a shallow list of twenty tools 👌 I solve problems where technical complexity meets business pragmatism 👌 I lead, mentor, and review - helping teams move faster while staying clean Core expertise: ✅ Languages: C#, JavaScript, Python, PHP, SQL, YAML ✅ Backend: .NET Core, ASP.NET Core, Web API, Entity Framework, microservices, CQRS, DDD, OAuth, Azure AD B2C ✅ Frontend: React, Vue.js, Angular, HTML5, CSS3, Bootstrap, Material Design ✅ Cloud & DevOps: Azure, AWS, Docker, Kubernetes, Azure DevOps, CI/CD, Playwright ✅ Databases: SQL Server, MongoDB, MariaDB, high-scale data modeling ✅ AI & Automation: OpenAI, Azure OpenAI, GitHub Copilot, Claude Code, n8n Services: 🔧 Custom web & API development 🔧 Legacy modernization & cloud migration 🔧 Microservices & distributed systems 🔧 Secure authentication systems 🔧 SQL Server performance tuning 🔧 Azure DevOps & CI/CD automation 🔧 Docker/Kubernetes/Azure/AWS 🔧 Code & architecture reviews 🔧 Performance optimization & refactoring 🔧 AI integration & workflow automation Both clients and colleagues consistently point to the same things: my reliability, clear communication, and ability to anticipate problems before they become bottlenecks. My approach is simple - understand the goal, design the right solution, communicate clearly, and deliver clean, maintainable software that scales with your business. If you need someone to architect a complex system, modernize an aging platform, untangle a hard technical problem, or raise the bar on your team's engineering, let's talk. 🚀
