Let’s discuss your project.

I’ve been building software for over 35 years, and if there’s one thing I’ve learned, it’s this: great code isn’t enough. What matters is creating apps that actually work for people — apps that save time, make life easier, and feel effortless to use. That’s where I come in. I have experience building web, mobile, and Windows apps, from idea through finished product. I’ve worked with C#, C++, PHP, Python, Java, JavaScript, Swift, Kotlin, HTML5, CSS3, Angular, React, ASP.NET, Blazor, Xamarin, MAUI, Uno Platform, React Native, WPF, UWP, Node.js, and more. I’m comfortable working across different platforms, tech stacks, and project types to help turn ideas into working software. What I Bring to the Table - I have 4+ years of experience adding AI features to apps using Azure OpenAI, OpenAI, Anthropic, Fireworks, Hugging Face, OpenRouter, and xAI. I work with custom agents, orchestration, tool harnesses, Text-to-Speech, Speech-to-Text, text-to-image, text-to-video, chat, and other AI features that help businesses automate tasks, improve support, and make smarter decisions. I also use AI development tools like GitHub Copilot, Claude Code, Codex, OpenCode, Grok Build, Warp.dev, Kilo Code, and Cursor AI to work efficiently and choose the right tool for each project. - AI quality & evaluation experience: I’ve reviewed and evaluated large volumes of AI-generated text and video content, identifying inaccuracies, hallucinations, bias, and guideline violations, and providing structured feedback to improve output quality and consistency. - Prompt and validation optimization: I improve AI reliability by refining prompts, validation logic, skills, and review workflows, reducing rework and making AI outputs more dependable in real-world applications. - Testing that catches what others miss: Selenium, Postman, Appium, NUnit, xUnit, MSTest, Cypress, XCUITest, JMeter — I’ve set up both unit and UI automation across multiple platforms. - Databases that scale: MS SQL, PostgreSQL, MySQL, SQLite, DynamoDB, MongoDB, Oracle. I design, optimize, and keep them running fast. - I have experience with Azure, AWS, Google Cloud, and Oracle Cloud, including building and maintaining deployments with Azure DevOps, TeamCity, GitHub, AWS Lambda, Docker containers, Kubernetes, and integrated services across multiple providers. - Integrations that “just work”: From QuickBooks Online, Twilio, Dynamics, AI Providers, UPS/FedEx, merchant gateways, logistics systems, IoT, production scanners, Logistics, IOT, veterinary systems, and even aircraft engine data — I’ve connected it all. Real performance wins: I’ve taken processes from 39 hours down to 2, 30+ minutes down to 2–3, 14 hours down to 20 minutes, and others from days to mere minutes. Optimizing systems is one of my favorite challenges. The Projects I’ve Loved Most: - LMS mobile apps for learning on the go - Sports stats tracking apps for basketball, baseball, soccer, and football - Enterprise systems for Associations, MLM, manufacturing and more - QA testing software that helps teams automate and catch bugs early - App store setup and deployment — getting apps live on iOS and Android without the headaches - Mobile scanning apps for warehouses and delivery teams - Restaurant and mail-order systems - Vet apps across multiple platforms - Web portals for clients - Production line integrations that track, scan, and sync in real-time And through it all, I’ve kept one promise: clear communication and transparency. You’ll always know where your project stands, what’s been done, and what’s next. Whether you need a cross-platform app, a cloud + AI solution, or a system overhaul that saves serious time, I can help. Let’s build something that works better than you imagined.

Senior C# / .NET & React Full Stack Developer | 7+ Years | AI & RAG Specialist Senior Full Stack Developer with 7+ years of hands-on experience in C#, .NET, and React, building production-grade web applications for healthcare, fintech, and SaaS companies. Over the last two years, I've focused heavily on integrating LLMs and RAG pipelines into existing .NET systems — turning AI from a demo into a feature that holds up in production. I'm not a generalist who lists every framework on the planet. My core is C# / ASP.NET Core on the backend and React / TypeScript on the frontend, and that's where I do my best work. Everything else (Azure, AWS, vector databases, CI/CD) supports that core. 𝐖𝐡𝐚𝐭 𝐈 𝐡𝐞𝐥𝐩 𝐜𝐥𝐢𝐞𝐧𝐭𝐬 𝐛𝐮𝐢𝐥𝐝: - C# / .NET backends — ASP.NET Core Web APIs, microservices, Entity Framework Core, Dapper, SignalR - React frontends — React, Next.js, TypeScript, responsive UIs, component libraries, state management done right - AI features in .NET apps — RAG pipelines, Azure OpenAI integration, semantic search, vector embeddings with pgvector / Pinecone / Azure AI Search - Full stack SaaS products — from database schema to deployed React app, including auth, payments, and admin dashboards - Legacy modernization — migrating WinForms / WPF apps to modern React + .NET Core web stacks without breaking the business - Cloud deployment — Azure and AWS, Docker, Kubernetes, Azure DevOps CI/CD 𝐂𝐨𝐫𝐞 𝐬𝐭𝐚𝐜𝐤 (𝐰𝐡𝐚𝐭 𝐈 𝐮𝐬𝐞 𝐝𝐚𝐢𝐥𝐲): - Backend: C#, .NET 8, ASP.NET Core, Entity Framework Core, Dapper, SignalR, Hangfire - Frontend: React, TypeScript, Next.js, Tailwind, Blazor - AI / LLM: Azure OpenAI, OpenAI API, RAG, vector search, embeddings, semantic ranking - Databases: SQL Server, PostgreSQL, Redis, Elasticsearch - Cloud & DevOps: Azure (Azure AI Engineer Associate certified), AWS, Docker, Kubernetes, Azure DevOps, GitHub Actions - Testing & Quality: xUnit, FluentValidation, Serilog, Seq 𝐖𝐡𝐲 𝐜𝐥𝐢𝐞𝐧𝐭𝐬 𝐤𝐞𝐞𝐩 𝐦𝐞 𝐨𝐧 𝐥𝐨𝐧𝐠-𝐭𝐞𝐫𝐦: Clear communication, honest estimates, and code other engineers can actually read six months later. I'd rather tell you a feature needs three weeks than promise one and disappoint you. I work well inside Agile teams and I'm equally comfortable owning a feature end-to-end as a solo contractor. If you need a C# / .NET and React Full Stack Developer who can also build real AI features into your product — not just glue together prompts — let's talk about what you're working on.
