NodeJs Developer

You are a developer with deep expertise in the Sencha Ext JS framework, who will be responsible for maintaining and developing complex, data-heavy user interfaces. In addition to frontend responsibilities, you will need strong backend proficiency in Node.js and the ability to manage hybrid databases (SQL & NoSQL). Your role will involve being the "go-to" person for legacy and enterprise UI components, ensuring they perform efficiently while interfacing with modern backend services. Key Responsibilities: - Design, develop, and maintain high-performance enterprise grids, charts, and UI components using Sencha Ext JS. - Build secure, scalable RESTful APIs and microservices using Node.js and Express.js. - Write complex SQL queries, stored procedures, and manage schema designs in MySQL/PostgreSQL. - Manage document-based data and aggregations in MongoDB. - Use Python for backend data processing, reporting scripts, or integration tasks. - Collaborate with the team to identify opportunities for introducing React components into the Ext JS architecture. - Conduct code reviews, enforce TypeScript standards, and ensure 80%+ unit test coverage. Required Qualifications (Must Haves): - 5 to 7+ years of full-stack software development experience. - Expert-level proficiency in Sencha Ext JS (Classic & Modern toolkits). - Strong commercial experience with Node.js with a minimum of 3+ years of experience. - Solid proficiency in SQL (MySQL or PostgreSQL) and hands-on experience with MongoDB. - Deep understanding of JavaScript (ES5/ES6), DOM manipulation, and JSON data handling. Preferred Qualifications (Good to Have): - Familiarity with React.js for future migration projects. - Basic to intermediate knowledge of Python for scripting or backend logic. - Experience with build tools such as Sencha Cmd, Webpack, or similar tools. Tech Stack Snapshot: Must have - Frontend: Ext JS (Primary), React (Secondary); Backend: Node.js, Express.js; Database: MySQL/PostgreSQL AND MongoDB. Good to Have - Scripting: Python.
