You will get a functional SaaS MVP or business web app prototype

Project details
You will get a structured SaaS MVP or business web app prototype built around a clear workflow, usable screens and practical business logic.
This project is for founders, small businesses and operators who need a clean first version of an app, dashboard, internal tool, customer portal, AI-assisted workflow or database-driven web system.
The depth of the work depends on the package selected. The Starter package is best for planning, scope clarification and a simple prototype. The Standard package is for a focused functional MVP with core screens, database structure and key workflows. The Advanced package is for a fuller MVP with more complete app logic, dashboard behaviour, integrations and launch support.
I focus on more than just the interface. I help clarify the user journey, version-one scope, database structure, admin process and the core logic needed to make the product useful.
This is best suited to new builds and focused MVPs. It is not intended for large enterprise platforms, heavy legacy migrations or complex infrastructure projects without a separate review first.

About Lewis
Web App & MVP Developer | Shopify, SaaS & Business Systems
Leicester, United Kingdom - 10:14 pm local time
My background is in ecommerce, purchasing and business operations, so I approach projects from a practical commercial angle. I do not just look at how a site or app looks. I think about the workflow, the customer journey, the data structure, the admin process and whether the finished system will actually be useful day to day.
1. SaaS MVPs & Web Apps
* Functional web app prototypes and MVPs built with modern tools such as Next.js, React and Supabase.
* User accounts, authentication flows, dashboards, forms and structured databases.
* AI integrations and API workflows using tools such as OpenAI, Anthropic, Gemini and other modern platforms.
* Clean build planning so the first version is useful, realistic and easier to maintain.
2. Shopify Store Builds & Ecommerce Setup
* Fresh Shopify store setup using clean, modern themes.
* Product, collection, navigation, payment, shipping and app configuration.
* Frontend layout adjustments so the store feels aligned with the brand.
* Practical ecommerce structure based on how customers browse, enquire and buy.
3. Static Websites, Landing Pages & Marketing Sites
* Lightweight business websites, landing pages and multi-page marketing sites.
* Responsive layouts built with tools such as Tailwind CSS, WordPress, Shopify or modern frontend frameworks.
* Clear calls to action, enquiry forms, booking flows and lead capture.
* Simple, practical site structures focused on helping visitors understand the offer and take the next step.
4. Business Systems & Workflow Tools
* Internal dashboards, lead trackers, quote request systems and customer portals.
* Automation of repetitive admin tasks using forms, databases, APIs and AI tools where useful.
* Practical systems for small businesses that need better structure without unnecessary complexity.
* Clear documentation and handover so the finished build is understandable and maintainable.
I work best on clean, modern builds where the goal is to launch something useful without overcomplicating the first version. I am especially suited to founders and operators who need help turning a rough idea, workflow or business problem into a clear build plan and working product.
I am not the right fit for heavy legacy migrations, large infrastructure projects, complex enterprise systems or taking over fragile production platforms without a proper review first.
If you need someone who can think through the business logic as well as the build, I’d be happy to help.
