Do you have a Java job and are looking for a talented and experienced Java Developer? I believe that my experience and skill in this background will prove to be of great help to you. I have worked as a Java Developer and Javascript Programmer (ExtJS 4.x) for years and my skills and experience will prove useful to your work. I have also worked as a Java/ J2ee developer with total 16.5 yrs of experience. I also possess proficiency in various areas like Spring, Hibernate etc. I am ready to start working on your job.
An Ext JS developer is a JavaScript specialist who builds data-intensive enterprise web applications using Sencha's Ext JS framework, delivering complex grids, dashboards, and single-page interfaces. Hiring a skilled Ext JS developer accelerates the build of admin panels, internal tools, and large-scale business applications that demand performance, structure, and a polished component-driven UI.
Ext JS developers design, code, and maintain front-end applications built on the Sencha Ext JS framework. They work with the framework's MVC and MVVM architecture, ViewModels, Stores, and component library to assemble interfaces that handle large datasets and complex user workflows. The work goes beyond visual layout — it includes data binding, REST and SOAP integration, custom component development, and performance optimization for thousands of records rendered in grids and trees.
Most Ext JS work centers on enterprise software: ERP modules, CRM dashboards, financial reporting tools, healthcare portals, logistics platforms, and government applications. These projects typically require deep familiarity with Sencha Cmd, the Ext JS class system, and integration with backend services written in Java, .NET, Node.js, or PHP.
Ext JS sits inside a broader JavaScript toolchain, and competent developers are fluent across that stack. Look for hands-on experience with Sencha Cmd, Sencha Architect, and Sencha Themer for application scaffolding, theming, and build automation. Familiarity with Sencha Test or Jasmine for testing, and Git for version control, is standard.
On the integration side, Ext JS developers regularly work with REST APIs, JSON, XML, WebSocket connections, and OAuth authentication flows. Backend pairings vary by project — Java with Spring Boot, .NET, Node.js with Express, or PHP with Laravel are all common. Strong candidates also know modern JavaScript (ES6+), HTML5, CSS3, SASS, and have working knowledge of adjacent frameworks like Angular, React, or Vue, which helps when migrating or interoperating with newer systems.
Strong Ext JS candidates show a portfolio of complex, data-driven applications — not marketing sites. Look for screenshots or demos of grids handling large record sets, custom components extending base classes, and dashboards combining multiple stores and views. Years of Sencha experience matter, but version coverage matters more: a developer who has shipped on Ext JS 6 or 7 with the modern toolkit will be more useful for current builds than one whose experience stops at version 4.
Ask for evidence of MVVM patterns, ViewModel binding, and custom theme work. Check whether they've performed migrations between Ext JS versions, since migration projects demand intimate knowledge of breaking changes and deprecated APIs. Profile signals to weigh: completed enterprise projects, written client reviews mentioning grid or dashboard work, and verified test scores in JavaScript and Sencha topics.
Sample interview questions you can use:
Ext JS is a specialist framework, and finding developers with genuine production experience in it is harder than sourcing generalist JavaScript talent. Freelancer.com gives you direct access to a global pool of Ext JS developers, Sencha specialists, and full-stack engineers who have shipped enterprise applications across industries. You can compare portfolios, read verified client reviews, and evaluate skill test results before you hire on Freelancer.com.
Clients set their own budgets and receive competitive bids, so pricing scales with project complexity rather than agency overhead. Milestone Payments give you payment protection throughout the engagement, and live chat lets you interview candidates and clarify scope before awarding the project. Whether you need a short migration sprint or a long-term build, freelancers on Freelancer.com cover the full range of Ext JS work.
Ready to build or modernize your enterprise application?
Hiring an Ext JS developer is straightforward when you scope the work clearly upfront. The framework rewards specificity — version, toolkit, backend, and component requirements all shape who is the right fit. The three steps below walk you through posting, reviewing bids, and awarding the project.
The quality of bids you receive is directly tied to the quality of your brief. A vague request attracts vague proposals, while a precise scope filters for developers whose Ext JS experience genuinely matches your needs. Head to the
Bids on Ext JS projects are short proposals, not just price quotes. They reveal how the developer interprets your brief, what architecture they propose, and whether they have actually shipped Ext JS work before. Read the proposals carefully and shortlist developers whose understanding of the framework and your domain matches the brief.
The final decision combines proposal quality with profile evidence. Look at portfolio depth, client reviews, and verified credentials, weighing consistency across multiple Ext JS projects rather than a single strong example. Migration experience, version coverage, and enterprise domain knowledge are the markers that matter most for this skill.
Timelines vary with scope. A single custom component or small dashboard module can be delivered in one to two weeks, while a full enterprise application or a migration from Ext JS 4 to 7 typically runs several months. The clearer your brief and API documentation, the faster a developer can scope and ship.
Yes. Many clients hire on Freelancer.com for fixed-scope work such as building a specific grid view, fixing performance issues, theming an existing app, or migrating a legacy ExtJS codebase. You can also engage developers on an hourly basis for ongoing maintenance and feature additions.
A general JavaScript developer works across libraries and frameworks like React, Angular, or Vue. An Ext JS developer specializes in Sencha's Ext JS framework, including its class system, component library, MVVM architecture, and Sencha Cmd build tooling. For Ext JS projects, framework-specific experience produces faster, more maintainable results than retraining a generalist.
If your backend is already built and stable, a front-end Ext JS developer is usually enough. If you need API design, database work, and the Ext JS UI delivered together, look for a full-stack candidate with proven Ext JS experience plus your chosen backend stack — Java, .NET, Node.js, or PHP are the most common pairings.
Yes. Ext JS continues to be maintained by Sencha and is widely used in enterprise environments where complex data grids, security, and long-term support matter. Many large organizations have multi-year roadmaps built on Ext JS, which is why specialist developers remain in demand for new builds, migrations, and ongoing maintenance.
