    For most of my over 10-year career, I've written and debugged a variety of software and have solved various types of problems. At Techno-Sciences, this was primarily software which handled communication between hardware devices with different protocols, and getting them to work together as a maritime surveillance unit. With Polycom, it was software which handled communication between Polycom's DMA and external hardware components such as phones, web services, and video conferencing devices. Then, with Spectra Logic, I wrote automated test code to debug communication between Spectra's backup software and various hardware storage devices, as well as cloud storage services such as S3. Next, with RK Mechanical, I programmed software to import product and price data from various APIs and data sheets and consolidate it. After that, with Exolvo Designs Group, I am enhanced software for a search-and-rescue antenna configuration system. And now, with Versity, I've done Golang programming for a data storage analysis tool and am currently doing bats testing for an AWS S3 gateway. In addition to my current contract at Versity, I'm open to freelance work in any field I find engaging, fields where I can put software together to solve problems and improve my knowledge. Skills: * bash/bats * Golang * github-actions * REST API * React.js * Docker * AWS * SQL Server * Python * MongoDB * Java * C++

Hi, I’m Brian Hurst, During my freelance career, I have designed and coded full websites from scratch, built and integrated plugins for WordPress, built end-to-end ecommerce websites, and created web apps for interactive user experiences serving a multitude of functions. I am not afraid to tackle new challenges and will work my hardest to complete any task I set my mind to. As part of my preferred development stack, I am an expert with the WordPress platform. With this technology I can create both simple & complex websites with smoother functionality that take advantage of the latest web standards and trends. My knowledge of WordPress allows me to optimize websites for quicker loading times and seamless experience across pages. I can also create fully custom themes with designs you provide, or we can work together to find a design that fits your idea. In addition to custom themes, I can modify any theme you may have and create new features and functionality within it.

My goal is to provide exceptional technical and customer support for each client I work with. I’m looking to become a long-term, go-to option for your online business. And with that mindset, there is no project too great, or too complex for me to complete. I promise to bring the highest quality coding standards and work ethic to your business. If I can’t complete the job, and complete it well, it probably can’t be done. You can contact me anytime, I’m always around and I work much more than I sleep.

    Hi, my name is Nathan, and I'm a software engineer specializing in mobile application development. I have my Master's in Software Development from Boston University, focusing on front-end frameworks and user interfaces. My experience ranges from R&D consulting to enterprise mobile applications. I am on Upwork because I am passionate about helping entrepreneurs take their idea from napkin notes to App Store. I structure projects around an 8 week development cycle for deployment to both the App Store and Google Play. React Native makes this possible with its write once, deploy everywhere approach. Below is a recommended 8 week timeline for a simple complexity app*: Week 1: Kick-off meeting and determining requirements Week 2: Wireframing and design Weeks 3 - 6: App development Week 7: Beta version testing WEek 8: Deployment *Applications range in complexity and customization. While the above is the goal for a simple complexity app (i.e., clone of existing concept, packaged elements, etc.), a more custom app will follow a different delivery schedule. I look forward to hearing your big idea!

    I've been meeting business and consumer needs by building and maintaining software in small teams for nearly 20 years. Whether you’re starting a new project, fixing or enhancing an existing one, or looking to elevate your own skills, I can help you achieve the results you’re looking for. My strongest area is browser-based development, from standards-compliant HTML, JavaScript/TypeScript, and CSS to complex single-page apps built with frameworks like React and Redux. I'm also proficient with server-side languages and technology like C#, PHP, and node/deno, but I haven't done much significant with JVM languages (Java, Kotlin, Scala). In addition to serving web pages and apps, I've created and maintained APIs, built message production/processing systems (RabbitMQ, GCP PubSub), and done a fair amount of payment processing.

    I’m Paul, a seasoned web developer and CRO specialist with over a decade of experience. Over the course of my career, I’ve had the opportunity to work with a wide variety of businesses from startups to publicly traded companies. In fact, you may recognize a few of my clients: Guy Fieri Manscaped Scotts Miracle-Gro Red Bull Samsung Western Governors University Scholl Atom Tickets Litter Robot Prestigify Graphene-X GymWear UK Chloe Dao Napapijri Formula Fun Foamies NASM (National Academy of Sports Medicine) When it comes to CRO, there are no "one-size-fits-all" solutions. If we were to work together, I would take the time to understand your problems and craft a unique plan to achieve them. That being said, most of my CRO projects begin with a thorough audit of website performance, where I conduct user research and analytics reviews to identify user behaviors and key pain points, focusing on foundational optimizations upfront. After that, I usually move into audience-focused, behavior-driven personalization and A/B testing. Over time I continue to perform iterative testing and refinement to improve conversion rates. For my web development projects, I typically begin by gathering requirements and identifying opportunities to enhance user experience. Then, I create prototypes and incorporate your feedback before proceeding with development and integrations that prioritize both functionality and user experience. After the development phase, I conduct user testing to ensure the site operates smoothly across all devices. And after deployment, I offer ongoing support for updates and optimizations as needed. I have experience using the following tools and platforms for CRO and web development projects: VWO Hotjar Django Flask Optimizely Shopify Plus Adobe Target Selenium WebDriver I’m proficient in the following languages: Python Java Kotlin Javascript CSS HTML Liquid SQL (PostgreSQL, MySQL) Whether you need assistance with website optimizations, web development projects, or UX/UI research, I'm here to help. If you think we could be a good fit, feel free to send me a message! I’d love to learn more about your business and explore how we’d work together.
