𝗧𝗼𝗽 𝗥𝗮𝘁𝗲𝗱 𝗣𝗹𝘂𝘀 | 𝟭𝟬𝟬% 𝗝𝗼𝗯 𝗦𝘂𝗰𝗰𝗲𝘀𝘀 | 𝟭𝟯+ 𝗬𝗲𝗮𝗿𝘀 | 𝟴,𝟬𝟬𝟬+ 𝗨𝗽𝘄𝗼𝗿𝗸 𝗛𝗼𝘂𝗿𝘀 | $𝟮𝟬𝟬𝗞+ 𝗘𝗮𝗿𝗻𝗲𝗱 | I'm a senior .NET / C# developer and Azure cloud architect who builds and scales production systems for companies that can't afford downtime or rework — healthcare platforms, fintech products, e-commerce systems, and real estate/property-management software. If your project needs more than someone who writes code to spec — if you need someone who can architect the solution, own the delivery, and still be there for support six months later — that's the role I take on. WHAT I BUILD ──────────────────────── ✦ SaaS Platforms — multi-tenant, subscription-based .NET Core / Azure applications built to scale from a handful of users to enterprise volume ✦ Healthcare Systems — HIPAA-aware EHR/EMR platforms, HL7/FHIR integrations, and clinical workflow tools built to compliance standards ✦ Fintech & Payments — secure transaction processing, Stripe/PayPal integrations, reporting and reconciliation systems, PCI-conscious architecture ✦ E-Commerce Platforms — custom storefronts, order/inventory management, and integrations with payment gateways, CRMs, and ERPs ✦ Real Estate & Property Management Systems — listing platforms, tenant/lease management tools, and workflow automation for property teams ✦ AI-Powered Features — OpenAI/LLM integrations, intelligent document processing, and AI-assisted workflows added to existing .NET applications ✦ Legacy Modernization — turning outdated ASP.NET/VB.NET systems into maintainable, cloud-ready .NET 8 platforms without breaking what already works TECH STACK ──────────────────────── + Backend: C# · .NET 8 / .NET Core · ASP.NET Core · ASP.NET MVC · Web API · Entity Framework Core · LINQ · Blazor · SignalR · Microservices · REST & SOAP APIs + Frontend: Angular · React · TypeScript · JavaScript · HTML5 · CSS3 · Blazor UI + Cloud & DevOps: Microsoft Azure (App Services, Functions, AKS, Service Bus, Key Vault, Azure SQL) · AWS (EC2, Lambda, RDS, S3) · Azure DevOps · GitHub Actions · CI/CD · Docker · Kubernetes · Infrastructure as Code + Databases: SQL Server · PostgreSQL · Cosmos DB · MongoDB · Stored Procedures & Query Optimization for high-volume systems + Integrations: Stripe · PayPal · Twilio · SendGrid · OAuth 2.0 · HL7 · FHIR · CRM/ERP integrations HOW I WORK ──────────────────────── I stay involved from architecture through deployment — writing clean, documented, production-ready code, and communicating progress clearly at every step. I manage scope, timelines, and stakeholder expectations as carefully as I manage the codebase itself. Depending on what your project needs, I can work as a hands-on senior engineer, a solution architect, or a long-term technical lead. I'll tell you honestly, early, if I'm the right fit for what you're building. Send me your project scope and I'll respond within a few hours.
