MERN Stack Developer | Scalable Web Apps with MongoDB, React, Node.js | Clean Code & UX-First Design

About

I'm a detail-oriented MERN Stack Developer with a strong foundation in building responsive and scalable web applications. I bring 5+ years of experience in fraud analysis at Wells Fargo, where I developed an analytical mindset and a passion for solving real-world problems — a drive that led me to transition into web development. During my career break, I pursued full-time hands-on training, mastering the MERN stack by building real-world applications. Through this journey, I honed my skills in: • Frontend frameworks like React.js, Redux Toolkit, Tailwind CSS, and DaisyUI • Backend technologies like Node.js, Express.js, and MongoDB • Authentication with JWT, Firebase, and role-based access • RESTful API design and deployment on Render, Netlify, and Vercel I’ve completed 4+ full-stack projects including: • A placement portal with admin access and analytics • A secure role-based employee feedback platform • A GPT-powered Netflix clone • A developer matchmaking app (DevTinder) I'm currently open to opportunities as a Full-Stack Developer, where I can contribute to innovative teams and build clean, scalable, and user-friendly web experiences. Let’s connect and build something impactful together!
