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document processing, and AI-assisted workflows added to existing .NET applications ✦ Legacy Modernization — turning outdated ASP.NET/VB.NET systems into maintainable, cloud-ready .NET 8 platforms without breaking what already works TECH STACK ──────────────────────── + Backend: C# ·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.

I am a Senior .NET/C# and AI Engineer with 7+ years of experience building reliable, scalable, and production-ready solutions. I specialize in developing Windows and web-based applications using ASP.NET Core, MVC, Web Forms, WPF, Windows Forms, and modern UI frameworks like Kendo UI, Telerik, Bootstrap, and jQuery. I am equally strong in backend logic, API development, SQL optimization, and performance tuning. Alongside full-stack .NET development, I build advanced AI systems using Computer Vision, Large Language Models (LLMs), and Document AI. I help businesses automate workflows, analyze images and video, extract insights from documents, and integrate AI into existing products.

12 years building production .NET systems. Fintech payment orchestration at Agoda, SaaS invoicing platforms, legacy modernization on Azure and AWS. My work is backend-heavy full-stack. Clean C# architecture, REST APIs built to hold up under real load, and frontends in Blazor or React that don't embarrass the backend. I've owned entire codebases solo and led small teams through complex deliverables. I'm most useful when a project is messy, stalled, or needs someone who can hit the ground running without hand-holding. Done this repeatedly on Upwork and in enterprise environments. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ⚙ Backend: .NET Core | ASP.NET Web API | EF Core | C# 🖥 Frontend: Blazor WASM | React | Redux | Angular | TypeScript 🗄 Databases: SQL Server | PostgreSQL | Redis ☁ Cloud: Azure | AWS | Azure DevOps | GitLab CI 🔗 Integrations: Stripe | Xero | FreeAgent | HMRC | Amadeus | FedEx | DHL ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ If your project involves .NET, a data-heavy backend, or anything in fintech or SaaS, let's talk.

Most hardware projects don't fail because of bad ideas. They fail in the messy space between "working prototype" and "shipping product." That's where I've spent the last 14 years — across 350+ projects and 50+ products now in mass production. Hundred clients have come back for a second project. Here's what's behind that number. I take products from napkin sketch to factory floor — designing the PCBs, writing the firmware, and optimizing the BOMs. That DFM work alone typically saves clients 20–30% on production costs. One client shipped at 12mA after coming to me with a prototype drawing 800mA in sleep mode. That's the difference between a redesign and a launch. The firmware I write runs 24/7 in industrial environments where a crash at 2 AM means someone's driving to a job site. I build for reliability first: FreeRTOS or bare-metal on STM32, ESP32, nRF52/53, RP2040, PIC, and Atmel. Connectivity — MQTT, BLE, Wi-Fi, LoRa, or cellular — gets chosen for the use case, not the trend. On the hardware side: multi-layer PCBs, proper signal integrity, IPC-compliant layouts (2221, 7351) in Altium and KiCad, built for manufacturability from day one. When the project calls for it, I wire the full IoT stack — AWS IoT Core, edge AI/ML inference, secure OTA, and fleet health monitoring. Top-Rated Plus. 100% Job Success Score. If you need an engineer who thinks in yield rates, field reliability, and unit economics — hit "Message" or "Invite to Job." Let's get your product out the door.
