Adam S.

I build custom websites, online stores, and software for businesses that need more than a standard template. Whether you want customers to request a quote, buy a product, book a service, or use an online tool, I can design and develop the experience around that goal. I'm Adam, the owner of Keystone Digital Systems. You'll work directly with me from the first conversation through launch. I handle the design, development, testing, and deployment, so the person discussing your project is also the person building it. My websites are custom built with HTML, CSS, and JavaScript. When a project needs more, I can add a database, account system, customer portal, admin dashboard, or connections to other services. I also build online retail storefronts with product catalogs, shopping carts, and checkout integrations. WordPress is an option when you specifically request it. My portfolio includes Beebe Drain & Sewer Co. and Camelback Plumbing, where the websites help visitors find the right service and request an estimate. For The Sanctuberry, I created a brand identity and website around the nursery's plants and story. I also designed Tea for Connoisseurs. I built Mailbind, a Chrome extension that exports Proton Mail messages and attachments into PDF, text, and ZIP files, with optional local encryption for ZIP archives. My software projects also include Politifree, which does not yet have a public website. Depending on the project, I work with TypeScript, Next.js, PostgreSQL, APIs, Netlify, Docker, and VPS hosting. I pay attention to responsive layouts, loading speed, clear navigation, and the technical foundations that help search engines understand a website. The technology serves the project, and I explain the choices in plain English. Before development begins, we agree on the scope, price, and delivery milestones. You'll review the design direction and important workflows before I build out the remaining pages and features. I test the finished work, help with launch, and provide the code, access, and instructions you need to manage it. If the scope changes, we discuss the cost and timing first. Send me your website or project brief through Upwork, along with your budget and target launch date. I'll give you a clear recommendation and a quote for the work involved.
