I’m a freelance software developer with several years of hands-on experience building digital solutions that are fast, secure, and scalable. I specialize in Web Development, Mobile App Development, and Blockchain Technologies, offering end-to-end services from planning and design to deployment and maintenance.
Web Development
My web development experience spans both frontend and backend technologies. I’m proficient in HTML5, CSS3, JavaScript, and TypeScript, and I work extensively with modern frameworks like React, Next.js, and Vue.js. On the backend, I use Node.js, Express, and MongoDB for full-stack applications, while also working with PostgreSQL and Firebase when projects require them. I prioritize writing clean, maintainable code, following best practices and ensuring SEO, performance, and accessibility standards are met.
I’ve built everything from business websites and e-commerce platforms to custom dashboards and SaaS applications. I’m comfortable integrating APIs, setting up cloud hosting (AWS, Vercel, Netlify), and working with tools like Git, Docker, and CI/CD pipelines.
Mobile App Development
I develop cross-platform mobile applications using Flutter and React Native, which allows clients to launch on both iOS and Android with a single codebase. My apps are designed with user experience in mind—visually appealing, intuitive, and optimized for performance. From prototyping UI with Figma to launching apps on the App Store and Google Play, I manage the full app lifecycle.
I’ve worked on apps ranging from booking systems and fitness trackers to fintech and e-learning platforms. My attention to detail ensures smooth animations, responsive layouts, and seamless third-party integrations such as payment gateways, geolocation, and push notifications.
Blockchain Development
I also work in the blockchain space, focusing on Ethereum-based smart contracts using Solidity. I’ve developed and deployed smart contracts for tokens (ERC-20, ERC-721), NFT marketplaces, DeFi platforms, and more. I’m experienced with Web3.js, Ethers.js, and integrating smart contracts with frontend interfaces.
Security is a top priority when building decentralized applications. I write gas-efficient and secure contracts, test thoroughly using tools like Hardhat and Truffle, and follow best practices to prevent vulnerabilities.
As a freelancer, I value clear communication, on-time delivery, and long-term client relationships. I’m proactive in solving problems, transparent in my process, and flexible in adapting to different project needs. Whether you're a startup looking to launch your MVP or a business aiming to scale your platform, I’m here to help turn your vision into a working product.
Let’s collaborate and build something exceptional!
