    "Cassandra has been an enormous asset for our company since we started working together about 1.5 years ago.... she created a stand alone billing software that has improved our billing process exponentially. This software does everything we could ask for and more, and she's always available to help me make improvements when ideas arise. I would strongly recommend Cassandra, she's a great developer and an even better person!" -Frank Piliero, Upwork: Developer with Javascript and API Experience, Jan 2022 "Cassandra fixed an issue I've been struggling with for months. She was super responsive and easy to work with." -River Braun, Upwork: Coder for Elementor Post Feed Bug, Dec 2019 "Cassandra was awesome. She built us a complicated front end calculator for clients that we are able to use on multiple sites and landing pages. And she was receptive to questions and changes. You can't go wrong with Cassandra!" -Rod Deutschmann, Upwork: Expert needed for the creation of interactive Glycol Calculator for Wordpress Website, Sep 2019 Hi, I'm Cassandra Gelvin. I build sites. I fix sites. I improve sites. I often work in WordPress, but I'm experienced in working with unique sites, unusual content management systems, or pure HTML, JavaScript, PHP, and ASP. Sometimes I'm a code detective, following the path of execution to find the problems. Sometimes I'm an architect, building sites from scratch, with only a designer's comp to guide me. I build systems and tools to help both clients and their customers. I've made calculators, created entry and display systems for events at a conference, and developed a billing interface using the API of the client's existing system. I track down obscure bugs and display issues. I help clients make their visions reality. I look forward to helping you build, fix, or improve your website.

    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.

    Working with a freelance developer can be stressful. If you run a small business, you already have enough stress. Now you’re faced with pulling off a software project with a programmer you hardly know. Beyond trusting the developer has the technical chops to get the work done, you hope your choice cares at least half as much about your business as you do. Good news: The right developer can remove the stress. I aim to be just that developer—a technology partner who unleashes the power of software to help your business shine. Here's what clients have said about my work: "Russ knows the tech and the human element of how to work with another person, treat the mission of the company as his own, and develop creative and efficient resolutions.” "The end product Russ delivered has helped our business grow exponentially." "Russ’s work ethic and dedication to his craft are unsurpassed." "Russ wasn’t a contractor; he was a partner. His quality of work was absolutely remarkable. My company would not be where it is without him." Every software project has two levels. First is the technology level where you lay out WHAT gets done: automating customer communication, building a new web-based service, etc. This level is about programming languages, servers, and databases. The second level concerns WHY you’re undertaking the project at all. Here the focus is on business goals like retaining customers or growing a market position. My mission is to operate seamlessly at BOTH levels to ensure your desired business results inform every technology decision. Operating at both of these levels matters because outsourcing development is a significant investment. When done right, a software project can be a game changer. But getting game-changing results shouldn’t be painful and shouldn't waste your time and money. You want someone who is responsive, dependable, and who fits into your team. The ideal developer "just gets it" and will never leave you hanging. These traits are born from a developer having a reason to care. I care because small business owners are among my favorite people. It’s a passion I delight in bringing into my work. Even more, I aim to make the intricacies of technology less intimidating. You know you need software, but it's common for terms like AWS, React, Ruby, JavaScript, or PHP to make your head spin. The software world seems to get more complicated by the day. How can you keep up and trust your developer is making solid choices? The answer is simple: experience and judgment. My programming credentials go back to the Commodore 64 days. I love technology and have created everything from a simple retail inventory system all the way up to financial trading tools processing millions of dollars per day. Every project has unique technology needs and tradeoffs. Having sound judgment to navigate those choices comes only with experience. No matter your comfort level with technology, I can put my years of experience to work and explain software options in simple terms. I’ll guide you through decisions that will serve your business well. Why don’t we discuss your project? There's no need to keep sitting on your ideas for that new system or ways to automate that pesky manual process. I'd love to learn about your business and figure out how I can help. If I think I’m not the best fit, I’ll be honest and say so. If we work together, you'll get a technology partner firmly committed to helping you achieve your business goals. I'd love to explore what you and I can do for your company! Please reach out, and we can set up a time to talk. Finally, I'm lucky that my services and experience are in demand. Consequently, I must turn down interview invitations every week. I try to respond personally to every invitation. But I can't always do that, especially for boilerplate requests without sufficient project details. So, please be as descriptive as possible in your request so I can more accurately judge how likely I am to be helpful. If I don't have time for a project at the moment that I think would be a good fit, I still like to respond in hopes of building a relationship. If you are flexible on timing, I can often get your project on the docket. I give the highest priority to projects likely to have a large impact within a small business. Thank you so much for your time. I look forward to hearing from you! Russ
