Project details
Plugin & Browser Extension Developer
I build custom browser extensions and plugins that automate tasks, connect with APIs, improve workflows, and add functionality to existing web applications.
I can handle the complete development process, from architecture and UI to development, API integration, testing, and deployment.
I can help with:
• Chrome, Edge and Chromium extensions
• Manifest V3
• JavaScript, TypeScript and React
• Content scripts and service workers
• Web page automation and DOM interaction
• REST and GraphQL API integration
• Authentication and secure API communication
• Chrome storage and local data
• Third-party integrations
• Custom extension dashboards and UIs
• Bug fixing and improving existing extensions
I have experience building browser extensions as well as full-stack applications, so I can also handle the backend, database, authentication, and APIs when your extension requires more than just frontend code.
If you have an extension idea or an existing plugin that needs improvement, send me the details and I can help turn it into a working product.

About Haidar
Senior Software Engineer | Full-Stack & AI Solutions
Swat, Pakistan - 3:02 am local time
Hi, I’m Haidar — a Senior Software Engineer with 7+ years of experience building web applications and digital products.
My main focus is full-stack development, from figuring out the right architecture and building the product to testing, deployment, and ongoing improvements.
I started my career working across the full stack and later specialized heavily in frontend architecture, so I’m comfortable working on both sides of an application. My strongest technologies are React, Next.js, TypeScript and Node.js, along with REST APIs, GraphQL, MongoDB, PostgreSQL, Docker and CI/CD.
I can help you with:
* Building a web application from scratch
* Turning an idea into a scalable technical architecture
* React / Next.js / TypeScript development
* Node.js backend and API development
* Database design and API integrations
* SaaS and business applications
* AI-powered applications and AI systems
* Integrating LLMs and AI features into existing products
* Improving or modernizing an existing codebase
* Performance optimization
* Authentication and payment integrations
* Docker, CI/CD and cloud deployment
I especially enjoy projects where I can take ownership of the whole technical process rather than just being handed frontend tickets.
For example, I can help you go from:
Idea → Architecture → Database → Frontend → Backend → AI → Testing → Deployment → Production
I've built and delivered 50+ projects for clients across the USA, UK, Europe and the Middle East, including travel platforms, booking systems, business applications, browser extensions and other custom software.
In my current senior role, I've worked on large-scale applications, frontend architecture, design systems and performance optimization, including improvements of 25–35% in application performance.
I'm also actively working with AI-assisted development and AI-powered workflows, and I'm interested in building useful AI systems that solve real business problems, not just adding an AI chatbot because it's trendy.
If you have an idea, an existing application, or a technical problem you're trying to solve, send me the details. I'm happy to look at it and suggest a practical way forward.
