Clayton C.
Full-Stack Engineer | Custom Business Systems & SaaS Applications
Growing businesses eventually outgrow spreadsheets, disconnected tools, and manual processes. I build custom software that turns those workflows into reliable systems your team can actually operate on. I work with businesses that need more than another off-the-shelf tool—whether that's an internal operations platform, SaaS product, client portal, real-time application, dashboard, or custom workflow connecting multiple parts of the business. My approach starts with understanding how the business actually works. From there, I design and build the application around the workflow rather than forcing the workflow around the software. 🛠️ CUSTOM SOFTWARE & SAAS DEVELOPMENT • Full-stack applications with Next.js, React, TypeScript, and PostgreSQL • SaaS products, internal tools, dashboards, and client portals • Authentication, role-based access control, and secure data access • Relational database design and application architecture • REST APIs, webhooks, and third-party integrations • Stripe subscriptions, checkout flows, and webhook-driven billing • Real-time application features and event-driven workflows • Responsive, production-ready user interfaces 💼 BUSINESS SYSTEMS & WORKFLOW ENGINEERING I can help turn manual or fragmented processes into software for: • Lead and client management • Project and task operations • Registration and event management • Customer and membership workflows • Quotes, contracts, invoices, and payments • Administrative dashboards and internal tooling • Automated data flows between existing systems ⚙️ INTEGRATIONS & AUTOMATION When custom software needs to work with the rest of your stack, I can integrate APIs, webhooks, databases, CRM platforms, payment systems, and automation tools such as Zapier rather than leaving you with another isolated application. 🤝 HOW I WORK I can take a project from requirements and architecture through implementation, debugging, deployment, and continued iteration. I also work effectively inside existing applications when you need an engineer to understand the current system, improve it without unnecessary rewrites, and build the next stage. I care about maintainability as much as getting the first version shipped. That means clear architecture, reusable components, secure authorization, sensible data models, and engineering decisions that leave room for the product to grow. If you need a full-stack engineer to build or improve a custom business system, SaaS application, or operational workflow, send me a message or invite me to your project.
