Need a secure Chrome Extension to automate workflows or a scalable SaaS platform built from scratch? I don't just write code; I architect complete digital products. I specialize in bridging the gap between browser environments and robust backend systems. Whether you are a founder building a new B2B SaaS, or a business needing a complex Manifest V3 Chrome Extension to streamline operations, I deliver secure, scalable, and premium solutions. Why clients choose me for complex builds: Chrome Extension Architect: I build secure, stealthy, and highly functional extensions using Manifest V3. From DOM parsing and API bridges to background service workers, I ensure they are bug-free, robust against dynamic web pages, and Chrome Store compliant. End-to-End SaaS Developer: I build the whole system. I connect the front-end dashboard to secure backend databases, handle user authentication (OAuth), and set up real-time data synchronization. Premium UI/UX Edge: Even heavy data applications should feel buttery-smooth. Because of my strong background in React, Tailwind, and GSAP, I ensure your SaaS doesn't just work perfectly—it looks like a million-dollar enterprise product. Strategic Problem Solver: I don't just blindly follow instructions. I proactively suggest architecture improvements, security fixes, and UI enhancements to make your product better. My Core Tech Stack: Browser Extensions: Chrome API, Manifest V3, Content Scripts, Service Workers, DOM MutationObservers Frontend: React.js, Next.js, TypeScript, Tailwind CSS, SCSS Backend & SaaS: Supabase (PostgreSQL), Firebase (Auth, Firestore), REST APIs, OAuth, Webhooks Premium UI (When needed): GSAP, Framer Motion Recent Project Highlights: Architected ClipSync, a complete micro-SaaS consisting of a Manifest V3 Extension and a Next.js Web App that securely synchronizes clipboard data across devices using Google OAuth and Firebase. Engineered a private, stealth B2B Chrome Extension for enterprise lead extraction, utilizing passive DOM parsing to bypass strict bot-detection limits. Ready to build a reliable, polished product?
