Over the years, I’ve worked across a range of stacks—React, Next.js, Angular, Python (Flask, Django), ASP.NET, Node.js, and Vue—often blending them with cloud platforms like AWS, Azure, and Firebase to deploy robust solutions. Whether it’s building sleek front-end interfaces or architecting back-end systems that handle thousands of requests per second, I take pride in making products that don’t just function—they perform. By 2022, I was leading full-stack projects using the MERN and MEAN stacks, helping startups launch MVPs in as little as 6 weeks. But I didn’t stop there. As demand grew for smarter, more adaptive systems, I began integrating AI into the products I built. I started with OpenAI’s GPT API, using it to power dynamic customer service bots. Then came automations: workflow engines built using tools like n8n, Make.com, and Zapier that helped businesses cut hours of manual work each week. One project I’m particularly proud of involved building an AI-powered concierge for a travel platform. The bot not only understood user intent from messy input but also remembered returning users, supported multilingual interactions (English + Mandarin), and triggered real-time booking workflows via a custom Node.js backend. What once required human agents was now fully automated—saving the client over 40 hours of support time each week. I’ve also containerized complex systems using Docker and orchestrated multi-service deployments, ensuring they remain stable under load. From crafting admin dashboards with React + Tailwind to deploying .NET APIs on Azure for enterprise clients, I’ve worn many hats—and enjoyed the variety. But beyond the tech, what drives me is problem-solving. Whether it's debugging an edge case at 2 a.m. or streamlining an onboarding flow to reduce churn, I thrive at the intersection of logic and creativity. I don’t just build for today—I build with an eye on what’s next. If you're looking for a developer who can combine engineering precision with creative insight to deliver solutions that are both smart and scalable, I’d love to connect Let’s build what’s next—together My Skills Frontend Development: React, Next.js, Angular, Vue.js, Tailwind CSS, HTML5, CSS3, JavaScript (ES6+), TypeScript Backend Development: Node.js, Express.js, Python (Flask, Django), ASP.NET Core, PHP Full-Stack Frameworks: MERN Stack, MEAN Stack Cloud Platforms & Deployment: AWS (EC2, S3, Lambda), Microsoft Azure, Firebase API Development & Integration: REST, GraphQL, third-party API integrations AI & Automation: OpenAI GPT API, n8n, Make.com, Zapier, custom workflow automation Databases: MySQL, PostgreSQL, MongoDB, Firebase Firestore DevOps & CI/CD: Docker, Docker Compose, container orchestration, GitHub Actions, Azure DevOps

A WinJS expert is a developer who specializes in the Windows Library for JavaScript, building HTML5, CSS3, and JavaScript applications for Windows 8, Windows 10, and Universal Windows Platform environments. WinJS provides controls, animations, data binding, and navigation patterns that make web technologies behave like native Windows apps. Hiring a WinJS specialist gives you targeted expertise for legacy Windows Store apps, in-house enterprise tools, and modernization projects that rely on the WinJS framework.
WinJS developers build, maintain, and migrate JavaScript-based applications that run inside the Windows runtime. The framework was originally released by Microsoft to let web developers ship Windows Store apps using familiar tooling, and it remains in active use across enterprise environments, kiosk software, and line-of-business applications. A skilled WinJS consultant translates business requirements into responsive, touch-friendly interfaces that integrate cleanly with Windows APIs.
Commercially, this skill matters when your organization holds existing WinJS code that needs continued support, bug fixing, feature extension, or controlled migration to newer stacks like UWP with TypeScript, React Native for Windows, or WinUI. A specialist protects your investment, reduces technical debt, and keeps mission-critical apps running on supported Windows versions.
A competent WinJS developer works fluently across the Microsoft ecosystem and the wider JavaScript toolchain. Expect proficiency with Visual Studio, Blend for Visual Studio, the Windows SDK, and the Windows App Certification Kit. They should also be comfortable with HTML5, CSS3, JavaScript ES6, TypeScript, jQuery, and Knockout.js where projects mix paradigms.
Adjacent skills that strengthen a WinJS engagement include Universal Windows Platform development, C# and XAML, WinRT components, Cordova for cross-platform packaging, Git version control, and Azure services for backend integration. Many WinJS contractors also bring experience with Node.js tooling, Webpack, and Jasmine or Mocha for unit testing.
WinJS expertise is most often needed in industries that deployed Windows 8 or Windows 10 line-of-business apps and continue to depend on them. Common scenarios include retail point-of-sale systems, healthcare clinical workstations, manufacturing floor dashboards, education and e-learning kiosks, logistics handheld applications running on Windows tablets, and government or defense apps with long support cycles. Media and entertainment companies also use WinJS for catalog browsing apps and second-screen experiences.
Look for developers with shipped Windows Store apps, public GitHub repositories containing WinJS code, and clear experience with the Windows Runtime. Strong candidates can describe the WinJS lifecycle, navigation model, and the differences between WinJS 1.0, 2.0, and 4.x. Portfolio markers worth verifying include published Microsoft Store listings, enterprise app screenshots, and contributions to the open-source WinJS project on GitHub.
Useful interview questions to ask:
WinJS is a niche skill, which makes finding qualified developers locally difficult. Freelancer.com gives you access to a global pool of vetted JavaScript and Windows platform specialists, including developers who shipped commercial WinJS apps during the framework's peak and have continued to maintain them. You can compare portfolios, ratings, completion rates, and verified reviews before you commit. Whether you need a short bug fix, a long-term maintenance contractor, or a migration architect, you can post a project on Freelancer.com and receive competitive bids from freelancers who match your stack and budget.
Ready to extend, maintain, or migrate your Windows JavaScript application?
Hiring a WinJS developer works best when your brief reflects the technical realities of the codebase. Because the framework is specialized, a precise project description filters out generalists and attracts JavaScript developers with genuine Windows platform experience. The three steps below walk you through posting, reviewing, and awarding the work.
The brief is the single biggest factor in bid quality. A vague post attracts vague proposals, while a specific brief brings developers who can speak to your exact WinJS version, integration points, and target Windows builds. Head to the
Bids are short proposals, not just price quotes. A strong WinJS bid shows the freelancer has read your brief, understands the framework's quirks, and has a realistic plan. Use the proposals to shortlist developers whose technical reasoning matches the work, and use Freelancer.com chat to ask follow-up questions before deciding.
The final decision should combine proposal quality with profile evidence. Review portfolio depth across multiple Windows or JavaScript projects rather than a single highlight, and pay attention to written client reviews that mention reliability, communication, and technical accuracy. Consistency across many projects matters more than one impressive screenshot.
WinJS is no longer under active Microsoft development, but applications built with it continue to run on supported Windows versions. Many organizations still maintain WinJS apps because rewriting them is costly, and a specialist can extend their useful life while planning a controlled migration to UWP, WinUI, or a web-based stack.
Yes. Experienced WinJS developers typically know UWP with C#, WinUI 3, React, Angular, and TypeScript, and can map WinJS controls and patterns to modern equivalents. They can deliver a phased migration plan that keeps your current app shippable while new modules are rebuilt on the target stack.
WinJS is a JavaScript library that lets web developers build Windows apps using HTML, CSS, and JavaScript. UWP is the broader Universal Windows Platform that supports multiple languages, including C#, C++, and JavaScript. WinJS apps can target UWP, but UWP also includes XAML-based development that does not use WinJS at all.
For most maintenance, feature work, bug fixes, and even mid-scale migrations, an individual WinJS freelancer is sufficient and more cost-effective. Agencies make sense only when you need a large, multi-disciplinary team covering design, backend, QA, and DevOps simultaneously. Freelancer.com lets you scale up by hiring multiple specialists for the same project when needed.
Small fixes and feature additions can be completed within days, while a full audit, refactor, or migration of an existing WinJS application usually spans several weeks to a few months depending on code size and integration complexity. Your freelancer should provide a phased timeline after reviewing the codebase.
