Hello! As a freelance full stack developer with expertise in various languages including C, C++, Delphi, C#, Java, Python, HTML, CSS, Javascript and SQL, I can assist you in building a wide range of applications and systems based on your needs. If you require a simple CRUD application, I can create a user-friendly interface and implement the necessary functionality to manage your data efficiently. Whether it's a basic application or a more complex one, I have the skills to deliver high-quality results. Building websites is another area of my expertise. I can design and develop websites of any kind, whether it's a personal blog, an e-commerce platform, or a corporate website. I am proficient in HTML, CSS, and JavaScript, allowing me to create responsive and visually appealing websites. If you need to build an API (Application Programming Interface) for your application, I can design and develop RESTful APIs that allow seamless communication between different systems or services. I can ensure that your API is secure, scalable, and well-documented. Complex web automation is also within my skill set. I am experienced in using libraries such as Requests and Beautiful Soup for tasks like data extraction and manipulation. Additionally, if you prefer to use Selenium for web automation, I can work with that as well. Scraping data from websites is another area where I can assist. I can develop scripts or tools to extract specific data points or gather information from multiple sources, providing you with the required data in a structured format. Importing and exporting data is crucial for many projects. Whether you need to migrate data between systems or integrate data from different sources, I can design and implement efficient solutions to ensure smooth data transfer and synchronization. Throughout the development process, I prioritize clean code, maintainability, and performance. I follow industry best practices and utilize version control systems to ensure the reliability and quality of the software I deliver. As a freelance developer, I am self-motivated and committed to delivering high-quality results. I am eager to collaborate with you and build exceptional software solutions that meet your specific needs. Let's work together to bring your vision to life!

If your looking for someone you can trust that has been developing and maintaining web apps successfully for over two decades, look no further. I build custom web apps and am strong with online payments (one-time & recurring), as well API integrations. --- Some recent examples of web apps I've built: * After a Stripe payment integration, an admin and client portal was designed and built for my client - a parasite testing company. Admins can manage the entire product line and client base from a single dashboard. Clients, affiliates, and resellers can manage all aspects of their account, and purchase additional products with discounts. This project also incorporated API work with ShipStation and USPS, including custom shipping labels and tracking. * Built a membership system for a sport coaching association. This web app included a page to register/pay (using Stripe) for individual coaches, and registration for groups. Once paid, coaches have access to a client portal to download/print/view their membership card as well as manage their account. Groups can upload their rosters, manage their coaches, and make payments through a Stripe integration or via PO invoices. An admin portal was built to provide a central location for managing memberships and communications for events. This client went from 250 registrations per year when we started to over 4,000+ active members each season. * Built a Progressive Web App (PWA) and Native IOS/Android App for a gas station/country diner. The web app allows clients to order food and gas station items. Clients can checkout as a guest or create an account. Registered users have a client portal where they can see all of their orders, update their profile, and re-order favorites. Clients can also download a native app to their iOS or Android device. An admin portal was built, which integrates with Square for inventory, payments, and kiosks - including ticket printing and counter pickup/checkout orders. --- I've worked on both internal and external APIs, and have used numerous first-party and third-party SDKs, as well as developed custom API integrations when an SDK is not available. * Payments & Financial (Stripe, Square, Authorize.Net, Codat, MX, Plaid, QuickBooks) * Shipping (FedEx, UPS, USPS, ShipStation, Endicia) * Communications (AWS SNS, AWS SES, Twilio, Aweber, Constant Contact, Mailchimp, Mandrill) * Content (SendSafely, DocuSign, DropBox, AWS S3, AWS Cloudfront) * Utilities (FontAwesome, Fusebox, JW Player, TinyMCE, Captcha, Maps, Analytics, HighCharts, MaxMind) --- My preferred technologies are Vue, Tailwind, Vite (or Webpack), Nginx (or Apache), PHP, MariaDB / MySQL / PostgreSQL, and Redis. I can and have worked with other stacks as requested. --- What My Clients are Saying: "I have worked with Art for over 15 years. He has done everything from site development, site design, API connection, testing, and deployment. He is always available for any changes, big or small, in a timely manner. I guess the best thing I can say about him is the work he does simply works. I highly recommend using his services as I will continue doing so as well." "Art and his team have worked with us for close to a decade. When I joined the company about four years ago, all I heard was "call Art, and he'll take care of it". It didn't take me long to realize how reliable and experienced he and his team are with complex coding and providing exceptional customer service. Once contacted, he gets back to me promptly, which is much appreciated. We are beyond happy with the service we receive from Art and his team and would recommend them to anyone looking for web app development." "We always enjoy working with Art. His work is superb and completed in a timely manner. In addition, he strives to create exactly what you need when you need it."
