About this gig
Encountering bugs in HTML, CSS, JavaScript, TypeScript, ReactJS, NextJS, ReduxJS, NodeJS, NestJS, ExpressJS, API integration, API Development or SocketIO?
Don't worry, I bring specialized expertise to diagnose and resolve issues, ensuring everything operates seamlessly.
I'm an expert in developing backend systems using Node.js, Nest.js, and Express.js, with additional proficiency in Firebase, Supabase, and AWS services including S3, Lambda, and SES. I've worked extensively with various ORMs like Sequelize, Mongoose, Prisma, Drizzle, and TypeORM across databases including MongoDB, MySQL, and PostgreSQL, and have integrated real-time functionalities using Socket.IO as well as API documentation using Swagger. I've also securely integrated payment gateways such as Stripe and Dragonpay, along with various other third-party APIs. On the frontend, I build scalable and responsive applications using React.js and Next.js, integrating state management through Redux, alongside a variety of CSS libraries and frameworks including Bootstrap, Material UI, Ant Design, and Tailwind CSS. I've successfully led and contributed to full stack projects.
