Hi, I’m Muhammad Mustafa—a full-stack engineer and SaaS founder with 10+ years of experience building web applications. I spent six years working remotely with AutoLeap, a Canadian SaaS company, contributing to software used by thousands of auto repair shops. My work included complex Angular applications, frontend architecture, state management, and Node.js integrations. I also founded and built CultureAI, an AI-powered employee engagement platform, handling everything from the React frontend and backend APIs to authentication, payments, and AI integrations. My strongest experience is in Angular, TypeScript, RxJS, and NgRx. I also build with React, Next.js, Node.js, MongoDB, PostgreSQL, and OpenAI and Claude APIs. On Topmate, I help developers and founders with: • Angular, React, and full-stack development mentorship • Code reviews, debugging, and application architecture • Frontend interview preparation and mock interviews • SaaS MVP planning, tech stack choices, and AI integration My guidance comes from working on live products, maintaining large codebases, and building my own software business. Bring your code, product idea, or interview questions. Book a session below, and we’ll work through your priorities and agree on practical next steps.
