Muhammad Shehryaar K.

🚀 A full-stack engineer building React and Next.js front ends, Node.js and Supabase back ends, and AI features (Claude, OpenAI) that people actually use, not just for showcase. 🏆 I have been developing Next.js and Umbraco websites for clients such as Jayco and Supra Industries since 2025. Top Rated Plus · $90K+ earned · 2,500+ hours worked. 💬 "We brought Muhammad onto our project at the very last minute to help us fix some critical errors that were holding up progress, and he delivered exceptionally." — Client review, React + AWS Amplify project, 2025 🎯 Most clients come to me at one of three stages: 1️⃣ Prototype to production: your application was constructed quickly and now it is failing to operate properly with everyday usage. It might have been assembled with Lovable, Bolt, V0, Cursor or Claude Code, or by a different programmer, and real data, real users or a real deadline will cause it to stop functioning. I will go through your code and let you know what the actual problem is as well as which parts of the code are fine, then I will correct the problem and get it into production. 2️⃣ You have a product already and need to add AI capabilities within it: an assistant that will answer questions derived out of your own documents, content creation support or an agent that will perform actions via your APIs. I can help in integrating Claude or OpenAI into existing Next.js or Node.js applications with proper cost management and monitoring of the AI model's responses. 3️⃣ You're in need of a senior developer who can be relied on for extended React/Next.js and/or Umbraco CMS projects. You need someone who can bring in new features weekly with minimal supervision. 📂 RECENT WORK 🔹 I've been working as a Full-Stack Developer at Bonsai Media Group since May 2025 on a remote contract worth $40K+ and counting. I contribute to both the frontend (using React/Next.js) and the backend (using Umbraco) for their brand clients. Two of the projects I work on there are My RV Selector (Jayco / Thor Industries), an application that helps RV buyers narrow down the selection and find the model that fits their needs, and Entegra Coach (Thor Industries), a high-end motorhome brand website with custom Umbraco Block Grid components. 🔹 Fantasyland Hotel, Edmonton: I built the entire website. 🔹 Production rescue: I joined the React + AWS Amplify project late, just before launch, and fixed the errors that were blocking production. ⭐ 5.0 rating. 🔹 Report Hub for Jira: I was the lead developer on the core and early versions of this Jira Cloud reporting app on the Atlassian Marketplace, built with Atlassian Forge and React. 🛠️ WHAT I BUILD 💻 Front end: Next.js (App Router), React, TypeScript, Tailwind CSS. Fast, responsive, SEO-friendly. ⚙️ Back end: Node.js, Express, REST APIs, PostgreSQL, MongoDB, Supabase, Stripe, third-party integrations. 🤖 AI: Claude and OpenAI APIs, document Q&A (RAG), tool-calling agents, LangChain and LangGraph. 🧩 CMS: Umbraco Block Grid components, templates and editor-friendly content models. ☁️ Deployment: Vercel, AWS Amplify, Azure, Docker, GitHub Actions CI/CD. 🤝 MY APPROACH ✅ When doing significant projects, we first start with a small paid discovery stage. This allows you to get a documented plan as well as an estimate of what the project will cost and what the possible risks are before you approve moving forward with the entire project. ✅ All of the work I do is available on your GitHub repo as soon as it is done, you will have opportunities to test little pieces of the project while it is being developed, and you will receive brief written updates every single workday. ✅ I use AI coding tools (such as Claude Code and Cursor) every single day to produce code at a much quicker rate, while testing all of the code prior to its release into production. ✅ Should something be delayed, I will let you know ahead of time with possible solutions. 💬 "Gem of a person, complex problem solver and skilled developer." — Client review, full-stack contract, 2025 🌍 I am in Islamabad, Pakistan, and my time zone overlaps with US morning time and UK/EU business time. Typically, I respond in a few hours. 📩 You don't need to send a complete specification in order to start working on things. You can simply send a link, a screenshot of the error, or tell me what you're building, and I will send a reply that describes how I would approach the project and an estimate of the time it will take.
