Full-Stack Web Application Development
We build custom web platforms using modern frameworks and scalable architecture. Not sure the idea is proven yet? Start with a PoC sprint. Our full-stack team handles everything from API development and database design to responsive front-end interfaces that work across devices.
Whether you’re launching a SaaS product, creating an internal dashboard, or replacing outdated systems, our custom web applications help you operate more efficiently and deliver value to your users.
Takeovers and rescues welcome
A growing share of our application work starts with someone else’s codebase: an app that stalled at almost-done, an AI-assisted build that demos well and fails quietly, or a system whose original team moved on. We audit first, then commit, and our AI code rescue service exists specifically for the vibe-coded variant of this story.
The audit tells you what you actually have before anyone bills for building on top of it.
The build ladder, priced honestly
Each rung exists so you never fund the expensive step to answer a question the cheap step could have answered.
Proof of Concept
Unproven idea. Test the risky part first.
- Two to four weeks, fixed scope
- Working demo plus written go/no-go
- Runs as a PoC sprint
MVP Build
Proven idea. Put a real v1 in front of users.
- Six to ten weeks
- Scoped to the smallest thing that tests demand
- React Native by default, native when needed
Production
Working product. Grow it without breaking it.
- Feature development and integrations
- Performance, security, and platform upgrades
- Takeovers welcome, audit first

Frequently Asked Questions
Do you build native apps or cross-platform?
React Native is our default recommendation: one codebase, both app stores, native performance where users notice it. We go fully native when a project genuinely needs it, which is less often than agencies selling two codebases would suggest.
What does a custom application cost?
An MVP build scoped to prove the business starts at $25,000, with most landing between $25,000 and $60,000 over six to ten weeks. If the core idea is still unproven, start smaller with a PoC sprint instead; it is the cheaper way to be wrong.
Can you take over an application another team built?
Yes, it is a growing share of our work, especially applications started with AI tools that stalled at 80 percent done. Our AI code rescue service exists for exactly that situation, and takeovers of human-built codebases follow the same audit-first process.
How long does an app take to build?
An MVP typically runs six to ten weeks. The honest variable is not the coding, it is decision speed: teams that answer questions in days ship in weeks, and we will tell you early if scope and timeline have stopped agreeing with each other.
