Qaiser Mehmood

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.**

Is your AI-powered MVP built on a fragile 'vibe-coded' foundation? Are you struggling to scale a prototype that was built with lightning speed but is now plagued by bugs, security holes, and technical debt? I transform brittle AI prototypes into robust, **production-ready applications**. As a senior AI engineer specializing in the **Node.js** and **React** ecosystem, I bridge the gap between rapid, AI-assisted development and the disciplined engineering required for scalable, secure software. But robust software is only half the battle. The other half is making it *work for your business*. I design and implement **intelligent automation workflows** that connect your apps, eliminate manual tasks, and free up your team to focus on high-impact work. Whether you need to rescue a failing project, automate a core business process, or build a scalable MVP from the ground up, I provide the expert oversight to ensure your AI initiatives deliver real, measurable value. **My Core Services:** * **🤖 AI Code Rescue & Remediation:** I conduct deep **AI code audits** to debug, refactor, and secure fragile codebases (especially those built with LangChain.js). I turn unmaintainable prototypes into stable, scalable assets ready for real users. * **⚙️ Intelligent Workflow Automation & Integration:** I design and build digital assembly lines for your business. I offer a full spectrum of automation solutions: * **Rapid Integration:** Using **Zapier, Make.com & n8n** to connect your existing tools and solve immediate process bottlenecks. * **Custom API Development:** Building custom **Node.js** APIs and webhooks to connect proprietary systems or handle complex logic that no-code tools can't. * **AI-Powered Decisions:** Infusing your workflows with intelligence using the **OpenAI API** to triage support tickets, qualify sales leads, or generate content automatically. * **🚀 Custom AI Solution Development:** I architect and build bespoke AI solutions from scratch, from **Custom GPTs** and intelligent **AI Agents** to complex RAG (Retrieval-Augmented Generation) pipelines that leverage your private data. * **👨‍🏫 AI Engineer & Career Mentorship:** I provide 1-on-1 coaching to help developers navigate the AI landscape, master tools like LangChain.js, and build a successful career in AI engineering and automation. **My Tech Stack:** * **Languages:** Node.js, TypeScript, JavaScript * **Frameworks:** React, Next.js, Express.js, NestJS * **AI / LLM:** LangChain.js, OpenAI API, LlamaIndex, Vector Databases (Pinecone, Qdrant) * **Automation Platforms:** Zapier, Make.com, n8n Ready to move past the prototype phase and build a real business? **Send me a message with your project details or book a session to get started.** --- ### Service Packages * **Package 1: AI Code Audit & Production-Ready Roadmap** * **Description:** Have an AI-generated MVP that feels unstable? I'll perform a comprehensive review of your codebase. You'll receive a detailed report identifying security vulnerabilities, performance bottlenecks, and a concrete, actionable roadmap to make your application **production-ready**. This is the perfect first step to de-risk your project. * **Package 2: Intelligent Automation Workflow** * **Description:** Let's put a core business process on autopilot. We'll map out a high-impact workflow and I'll build a robust automation to solve it. Ideal for **automating lead qualification**, **triaging customer support tickets**, or **streamlining content pipelines** using the best tool for the job—Zapier, Make, or custom Node.js scripts. * **Package 3: Scalable AI MVP Development** * **Description:** Need to build an MVP the *right* way? I'll architect and develop a **scalable MVP** from day one, using professional, spec-driven development practices. We'll build a strong foundation with clean, documented code and a modern stack (Node.js, React) to avoid the technical debt that plagues "vibe-coded" projects.

Both of us join the zoom call. You start the session timer and pause it. You share your screen and explain the problem statement. I do some research if necessary. We resume the timer and I try to help. Full refund if I do not succeed.
