I'm a web developer with experience in building websites and web applications for small and medium-sized businesses. Whether you need help designing and developing a website to increase traffic and leads, or creating a complex web application to save your business time or money, I can definitely help! - I'm experienced with and have professional experience working in Javascript/TypeScript, React, Next.js, Tailwind, HTML5/CSS3, and D3. - I can manage your entire project from start to finish, starting with a detailed plan of what I’ll be developing for you, how it works, and what it will cost. - Communication is my top priority -- if we're on the same page for the duration of the project, the entire experience will be a breeze for both of us. My main focus in web development is setting a strong foundation. If we're starting from scratch, I will research and take your needs into consideration when designing a solid tech stack. There are many mistakes people make when first building their websites and applications, and often having a messy foundation will make the maintenance and upgrades to your website more costly -- both in money and time. This is the main reason why I often suggest technologies like React, Next.js, and TypeScript. This combination has an extremely active and growing community, large financial backing, and a ton of developers who would love to work with it. This will make it easier to find future contractors or employees who can maintain and build new features on top of your existing application. If I will be working on an existing project, I'd love to help convert your codebase into a more maintainable one. In simple terms, I'd be cleaning up messy code, writing proper documentation, and fixing any problems that have been "swept under the rug". I pride myself on my troubleshooting capabilities when it comes to web applications, as I've seen and dealt with many bugs by leveraging tools like GitHub, StackOverflow, and my own personal network of software developers. If your codebase is already organized, or you are just looking to implement new features as soon as possible, I offer extremely quick development at a fixed price. I have experience with prototyping features quickly in React, and leverage existing libraries to streamline application development. I look forward to working with you, and invite you to reach out to me if you have any questions or would like to chat.
