๐Ÿ‘‹ Hello, I build web and mobile applications that actually work in production, not the kind that break right after launch ๐Ÿ˜. I am a Full Stack Developer (Web & Mobile) with 12+ years of experience building scalable SaaS platforms, mobile apps, and custom web applications using React, Node.js, Next.js, Flutter, and React Native, along with modern AI-powered solutions. I work with startups and growing companies to turn ideas into production-ready systems that are stable, maintainable, and built to scale โ€” not quick builds that need to be rebuilt later. Over the years, I have delivered 300+ web and mobile applications, from MVPs to large-scale platforms with real users and revenue.

At A Glance: Corona SDK

With more than 2 billion users globally, smartphones have become common household items for many people. Creating and developing programs that run on these smartphones, colloquially known as apps, is a powerful way for you and your business to reach this massive mobile market. Corona is a software development toolkit created and designed to allow programmers to design and build applications for mobile uses. Corona layers the C++/OpenGL and Lua programming languages to create a complete, dynamic toolkit for mobile applications. If you are looking to create, modify, or develop apps for the Android, iOS, or any other mobile operating system, consider the use and value of a Corona developer or programmer.

Corona developers are available on Upwork to help your business or project make the most of Corona code that has already been written, working with you to smooth out any problems or flaws in your mobile software, and making it easier and more complete for the targeted end user. Programmers can collaborate with other programmers within your organization or work independently to create software using Corona from the ground up, helping you give form and function to your mobile application ideas and vision. Both developers and programmers are highly skilled computer technicians with experience working on a variety of projects. Hiring a freelance developer or programmer gives you the option to select and work with the professional that best meets your needs. Corona developers and programmers are invaluable team members that, when leveraged correctly, can give you and your business unprecedented access to the mobile market.
