You will get a custom Chrome or VS Code extension (Manifest V3) with API integration
Project details
I build production-grade Chrome and VS Code extensions that hold up under real user traffic. I'm the creator of OpenRouter Agent, a live VS Code/Cursor extension with 3,000+ active developer users, so I know how to ship, secure, and maintain software people actually rely on.
What you get:
• Manifest V3 Chrome extensions and VS Code tools built the right way
• Secure API and LLM/AI integration (OpenRouter and others), background scripts, and content scripts
• Optional auth, paywalls, and subscription (SaaS) setup
• Clean, maintainable TypeScript/JavaScript with a polished, responsive UI
I pair AI-assisted speed with real engineering: I clear boilerplate fast, then focus on the hard parts, architecture, security, and state management. Message me your idea and I'll map out a clear technical plan before you order.

Front-end expert figma to react with the tailwind
Professional!! Working with Zihad was a fantastic experience! His prompt responses and excellent communication skills made the collaboration smooth and efficient. He was incredibly helpful in converting Figma to a responsive React project with Tailwind CSS.
His expertise in HTML/CSS/JavaScript, especially SCSS, and responsive development was top-notch. The way he used value unit (no fixed pixel for margin, padding, and others), is just incredible. Very nice fluid system with auto responsive almost, liked it very much. And I appreciate his suggestions, he knows very well what he is doing and is very very passionate.
I'm highly satisfied and recommend him to others. We'll definitely work with him on similar projects in the future.

About Zihad
Frontend Developer | React/Next, Vue/Nuxt, AI Agent Development, LLM
Barisal Sadar, Bangladesh - 4:00 am local time
Proof, not just a claim:
I built a RAG-grounded AI chat agent, full-stack, now live in production on client sites (see eurotelemobile.pt — click "Chat with us"). It answers only from real site content, cites its sources, reasons across multiple product records to answer comparison questions, and held firm against a direct prompt-injection attempt with zero leak. Built on Nuxt 4, OpenRouter (model-agnostic LLM routing), and Neon Postgres with Drizzle.
I built and published OpenRouter Agent, a VS Code/Cursor extension that 5,000+ users are currently using. Connects the editor to Claude, GPT-4o, Gemini, DeepSeek, and 300+ models through OpenRouter. Custom tool-calling runtime, file read/write, shell execution. Three modes: Ask, Plan, Agent. Streaming UI. Permission checks before anything destructive runs. Live on VS Marketplace, Open VSX, and GitHub.
What I do:
✓ AI agent development — RAG pipelines, multi-model routing via OpenRouter, tool-calling screens, guardrails against prompt injection
✓ AI product interfaces — chat UIs, multi-model routing, tool-calling screens, loading/error states that hold up when something breaks
✓ Vue/Nuxt and React/Next.js builds, from product requirements to production
✓ Animation — CSS for lightweight UI motion, GSAP for complex timelines, scroll interactions, SVG animation, and high-end marketing experiences
✓ Accessibility — keyboard nav, focus states, semantic HTML (learned on real projects, not a certificate)
✓ Static and marketing sites, when that's genuinely the right tool for the job
Client work spans hospitality, dining, travel, and events, and retail/e-commerce. Boutique hotels. Restaurant platforms. Car and fleet rental sites. Wedding sites. More going up in the portfolio as I add them.
Built with Vue/Nuxt, GSAP, and Supabase for interactive work. Clean static HTML/CSS from Figma when that's what the brief needs.
I've worked inside real dev teams — WebDynamic, 42Robots, Mango Studio. Git, GitHub, BitBucket for code. Slack, Notion, Asana, Jira, Meistertask for everything else.
Stack: Vue.js, Nuxt, React, Next.js, TypeScript, JavaScript, OpenRouter, RAG, LLM integration, Neon Postgres, Drizzle, HTML5, CSS3, SCSS, Tailwind CSS, GSAP, Supabase, Vercel, Cloudflare, Git, GitHub, BitBucket, Slack, Notion, Asana, Jira, Meistertask
I use Cursor and Claude Code daily. So I know which parts of frontend work they've made easy — and which parts still need someone paying attention.
Send me your stack, the user flow, and the hardest part of the problem. I'll tell you straight if I'm a good fit.
