We build custom software for your business. From internal tools to SaaS platforms — real full-stack applications with frontend, backend, database, authentication, APIs, and integrations. All in one place.
Tech Infused. Solutions Driven.
If your business currently manages something through spreadsheets, paperwork, email chains, text messages, or several disconnected software platforms, there's a good chance we can build a web app that brings that process together.
We're not limited to creating screens that only look functional. Here's what we can actually build behind the interface.
Frontend + Backend + Database
We're not limited to creating screens that only look functional. DunderBuildz can develop applications with real server-side functionality, persistent databases, authentication, APIs, integrations, and secure business logic.
Faster, Search-Engine-Friendly Pages
Pages can be rendered on the server before they're delivered to the browser. This provides faster initial content, search-engine-friendly HTML, better SEO capabilities, proper previews when pages are shared, and an improved user experience.
Secure Operations Behind the Scenes
Important operations can run securely on the server instead of inside the visitor's browser. This allows us to build functionality such as accounts, permissions, payments, calculations, database operations, file processing, automations, and integrations.
Different Access Levels for Everyone
Your application can have real user accounts with protected areas. We can create different access levels such as Owner, Administrator, Employee, Contractor, and Customer — so everyone doesn't have to see the same information.
Your Data Persists — It Doesn't Disappear
Your application's information can be stored in a persistent database rather than disappearing when someone closes their browser. Applications can create, retrieve, update, and delete information as your business operates.
Connect Your Business Tools
We can create API endpoints and connect compatible third-party services so your application doesn't have to operate by itself. Webhooks can also allow systems to react automatically when something happens elsewhere.
Sensitive Data Stays on the Server
Sensitive credentials don't belong inside publicly accessible browser code. Our applications can keep supported API keys, database credentials, authentication secrets, access tokens, and integration credentials on the server side, where client-side users cannot simply inspect the application and retrieve them.
You don't need to know React, TypeScript, APIs, databases, SSR, or authentication. You need to know what problem you want to solve.
