Yes, absolutely! I am fully open to remote software developer positions. I am highly comfortable with distributed team coordination, online standups, and standard collaborative tools like Git/GitHub, Slack, Jira, and Zoom.
I specialize in Frontend Web Development using JavaScript (ES6+), React.js, Next.js, and Tailwind CSS. I also build mobile apps using React Native & Expo, and have robust foundations in Core Java and backend API logic with Node.js.
I employ mobile-first CSS planning with Tailwind and custom breakpoints. For native platforms, I use React Native stylesheet wrappers to ensure consistent scaling across different screen sizes and pixel ratios.
I begin by detailing specifications, design mockups, and client UI expectations. From there, I structure clean component directories, implement client interactivity, connect required REST APIs, and perform extensive Lighthouse optimization before deploying.
Yes! I actively take freelance projects — from landing pages to full SaaS platforms and mobile apps. I ensure timely delivery, clean code, and thorough communication throughout the project lifecycle.
I have hands-on experience building and optimizing enterprise ERP and CRM dashboards at Optimizaum Infotech, using React.js, Tailwind CSS, ApexCharts for data visualization, and REST APIs for real-time data integration.
