About

I don’t just write code. I build, debug, and improve software that solves real problems. I’m Jebamalai Jero, a Full-Stack Developer working primarily with React.js, JavaScript, Node.js, Express.js, Sequelize, REST APIs, and SQL/MySQL. My day-to-day work involves building and integrating frontend and backend features, developing APIs, working with databases, handling business workflows, and debugging issues across the stack. I enjoy understanding how different parts of an application connect — from a React component and API request to backend logic and database operations. ━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT I DO ━━━━━━━━━━━━━━━━━━━━━━━━ ⚛️ Frontend Development Build responsive and user-friendly interfaces using React.js, JavaScript, HTML, and CSS. ⚙️ Backend Development Develop REST APIs and backend functionality using Node.js and Express.js, with Sequelize for database interaction. 🗄️ Database & API Integration Work with SQL/MySQL databases, API integrations, data handling, validations, and business logic. 🔧 Problem Solving & Debugging Investigate issues across frontend, backend, APIs, and databases — understanding the root cause instead of just fixing the symptom. 🔄 Full-Stack Development Work across the complete flow of an application, connecting UI, APIs, server-side logic, and data. ━━━━━━━━━━━━━━━━━━━━━━━━━ HOW I WORK ━━━━━━━━━━━━━━━━━━━━━━━━━ I like breaking complex requirements into smaller, workable pieces and understanding the “why” behind the requirement, not just implementing what is written. For me, good development is about writing code that is simple to understand, easier to maintain, and actually useful to the people using it. I'm continuously improving my skills, exploring better ways to build software, and looking for opportunities where I can take more ownership and grow as a Full-Stack Developer. Currently open to Full-Stack / Software Developer opportunities. 📩 Open to opportunities: Jebamalaijero.24it@licet.ac.in /Jerojeon110@gmail.com Let's connect if you're building something interesting, hiring for a developer role, or simply want to talk about software and technology. #FullStackDeveloper #ReactJS #NodeJS #JavaScript #WebDevelopment #SoftwareDevelopment #MySQL #RESTAPI
