You will get a custom AI-powered Chrome browser extension
Project details
The best browser extensions feel like a superpower bolted onto the web, summarize this page, rewrite this text, pull this data, automate this task - right where the user already is. That's what I build.
I create custom Chrome extensions with AI built in: a one-click summarizer, an in-page writing assistant, a data extractor, a research copilot, a workflow automator. Whatever your idea, I build the extension, the page interactions, and the AI feature, and publish it to the Chrome Web Store.
Need more than a solo tool? I build the full thing — user accounts, saved settings, payments, a backend, even a dashboard — and ship it cross-browser to Chrome, Edge, and Firefox.
I'm full-stack and JavaScript-native, so the extension, the AI, and any backend all come from one engineer, not stitched together from three.
Want to see it work first? Start with the Extension Prototype — I build the core feature in 4 days so you can try it in your own browser before committing.
Tell me what the extension should do and I'll tell you how to build it.

Looking for an engineer who can build your complete AI-powered product not just the frontend, backend, or AI layer?
I design and build production-ready AI applications from concept to deployment, combining modern full-stack engineering with LLMs, agentic workflows, and scalable cloud infrastructure. Whether you're launching a new AI SaaS platform, integrating AI into an existing product, or building an internal automation system, I deliver solutions that are reliable, maintainable, and built for real users.
I work across the entire product lifecycle—from architecture and UI to backend services, AI integration, deployment, and ongoing optimization—so you can work with one engineer who understands the complete system.
What I Build
* AI SaaS platforms powered by GPT, Claude, Gemini, and other LLMs
* AI Agents using LangGraph, CrewAI, MCP, and tool-calling workflows
* RAG applications with semantic search, document intelligence, AI copilots, and vector databases
* Voice AI and conversational applications using Whisper, ElevenLabs, Deepgram, and Twilio
* Modern web applications using React, Next.js, TypeScript, Node.js, FastAPI, and PostgreSQL
* Cross-platform mobile applications with React Native and Expo
* Workflow automation and data pipelines using n8n, Playwright, Puppeteer, and third-party APIs
* Multi-tenant SaaS platforms, dashboards, marketplaces, booking systems, CRM, ERP, and custom business applications

Scope the extension
We agree what the extension does, which pages it runs on, the trigger, and the AI feature, then I map it to Chrome's extension APIs.
Build the core
I build the extension — the UI, the page interactions, and the AI feature — and wire it to your chosen model and any backend it needs.
