A solar tech company in the Mojave Desert just outside Onyx needed a mobile app to track energy output across 12 remote solar farms. Their existing React Native codebase had fallen behind, with crashes on older Android devices causing daily support tickets. We embedded a Flutter developer for three months who rebuilt the app with a single codebase, cutting maintenance time in half and reducing crashes to zero. The team in Onyx now releases updates every two weeks instead of every six months.
When a logistics startup in Barstow decided to expand into the Inland Empire, their CEO realized their driver app couldn’t handle the new route complexity. The original developer had left two months before, and the remaining team spent weekends firefighting instead of building features. We matched them with a Flutter developer who specialized in route optimization, built a new navigation layer using Flutter’s platform channels, and delivered a working prototype in four weeks. The Barstow team now uses the app to manage 400 daily routes without a single outage.
Hiring a Flutter developer in Onyx shouldn’t mean waiting weeks for interviews or paying premium Silicon Valley rates. Our developers work directly in your Slack channel, sync during California hours, and own the entire app lifecycle, from Firebase backend setup to App Store deployment. You maintain full control over priorities while we handle the heavy lifting of cross-platform development.
The biggest mistake we see companies make is treating Flutter as just another mobile framework. Flutter’s real power comes from its reactive architecture, which lets you push changes to both iOS and Android simultaneously without app store approvals. For a company in Onyx that needed rapid iteration on a prototype, we used Flutter’s hot reload to test 15 UI variations in one afternoon. The client could see every change on their phone within seconds, something their previous developer couldn’t deliver.
Your developer overlaps with California hours via Slack and Zoom. We schedule meetings during your morning when we’re wrapping up our evening, so you never wait for responses during your workday.
We’ve built everything from complex internal tools for California wineries to customer-facing retail apps handling thousands of daily transactions. Our developers know which Flutter packages survive production and which ones cause technical debt.
Every line of Dart code belongs to you immediately. No proprietary framework lock-in, no licensing fees, no surprises when you want to bring development in-house or switch teams.
Our developers don’t rotate projects every sprint. The same person who builds your app in week one is still handling bug fixes in month six, which means they understand your business logic better than anyone else.
You get a Slack channel with your developer, weekly demo recordings, and access to the same project board your team uses. No weekly status calls unless you request them, just clear progress visibility.
Start with just 40 hours to evaluate the developer. If it doesn’t work out, we’ll match you with someone new at no extra cost. No contracts, no cancellation penalties, no games.
Your developer becomes part of your team during California business hours. You get consistent output, predictable billing, and the ability to scale up or down each month without renegotiating contracts.
Ideal for companies that have seasonal workloads or want to test the model before committing. You reserve 20 hours per week during your peak needs, with the flexibility to pause or adjust hours month-to-month.
One-off tasks or overflow work without the commitment of a retainer. Perfect for when you need an extra pair of hands for two weeks to meet a launch deadline or tackle a backlog spike.
Need multiple developers for a project? We can assemble a dedicated Flutter squad that works as a single unit under your management. Great for agencies juggling multiple client apps or startups scaling rapidly.
We start with a 30-minute call to understand your app’s requirements, existing tech stack, and key stakeholders. No sales pitch, just clear next steps based on what you need, not what we want to sell.
Within two business days, we introduce you to 2-3 developers who meet your technical requirements and communication style. You pick who you want to work with, and we make the introduction happen the same week.
Your developer spends the first five days setting up their local environment, reviewing your codebase, and configuring your CI/CD pipeline. You receive a full access report and a recorded walkthrough of their setup process.
No waiting for the next quarterly planning cycle. Your developer delivers a working build within two weeks, often a login screen or core feature that you can test on your phone the same day.
Every Monday you get a demo of what shipped the previous week, a priority list for the coming sprint, and a Slack update with blockers. No surprises, no missed deadlines, just consistent progress toward your goals.
