Freelance ASP.NET Core Developer - Qaiser Mehmood
Freelance ASP.NET Core Developer5.0 (7 reviews)

I **define the architecture**. For 21 years, I've been the person CTOs and lead developers call when systems fail under load, migrations are at risk, or AI integration needs to work right the first time. With expertise in **C#, .NET, Blazor, ASP.NET Core, SQL, Python,** and production AI agents (**Semantic Kernel, LangGraph, custom tool-calling**), I design systems where performance, reliability, and intelligent automation aren't optional—they're the baseline. I've shipped AI to **production** — not to a Jupyter notebook. I'm the creator of **FreeAIVoice** — a live AI voice platform with AI Voice Generation, Voice Cloning, and Speech-to-Text across **30+ spoken languages** and a developer API. I provided production systems for The New York Times. --- **Here's where I'm most useful to you:** - **The AI Integration Trap** — You've been asked to add AI to your existing .NET system but don't know whether to use *Semantic Kernel*, raw OpenAI APIs, or a Python sidecar. I've made that decision dozens of times. I'll make it faster and safer for you. - **The Blazor Bottleneck** — Your Blazor app is slow, state management is tangled, and you're unsure if you chose *Server or WASM* incorrectly. I can diagnose what went wrong and map a clean path forward — often in a single session. - **The Legacy Modernization Cliff** — You have a 10-year-old .NET system that needs AI or modern tooling but wasn't designed for it. I specialize in *incremental refactoring paths* that don't require a full rewrite and don't break what's already working. --- **What I Do Best:** - **Software Architecture & System Design** — scalable, maintainable systems from greenfield to enterprise - **AI Agent Development** — production-grade agents with Semantic Kernel, LangGraph & AutoGen — *not demos* - **Blazor & ASP.NET Core** — Server, WASM, hybrid — full-cycle development and performance tuning - **Python & AI Automation** — RAG pipelines, workflow automation, voice AI, LLM integrations - **Legacy .NET Modernization** — refactoring strategy, migration paths, incremental upgrades - **Architecture Audits** — identifying structural risk before it becomes a production incident, not after - **Debugging Complex Systems** — when the stack trace doesn't tell the whole story **If any of this sounds like your current situation — DM me. I respond to every message.**
