Hire engineering talent
Most mobile problems are not screen problems. Our Flutter developers have shipped against live ERP data, recurring payments and media at scale, and they can hold a conversation with whoever owns your API.

Businesses that run on what we built
The short answer
A feature area of your app end to end: the screens, the state, the API integration behind them and the store release that ships it. Senior developers can own the app architecture, the data and caching layer, payment flows and the release pipeline. They work in your repository and your process, and they can talk to your backend team about the API shape rather than waiting for one.
The apps behind this page are all connected products rather than standalone ones: a supplier catalog fed by Odoo over GraphQL, a subscription product with Stripe billing behind web and mobile clients, and a live remittance platform where mobile, web and ERP ship together.
That's the kind of Flutter work we can staff credibly. If your app is a pure offline utility with no backend, an excellent Flutter freelancer may serve you just as well, and we'll say so.
What you get
Ownership rather than years of experience. Read the "not included" rows as carefully as the rest.
| Capability | Developer | Senior developer | Mobile lead |
|---|---|---|---|
| Build screens and features in an existing app | Yes | Yes | Yes |
| State management and data caching | With review | Yes | Yes |
| GraphQL / REST integration and API feedback | With review | Yes | Yes |
| Payment and subscription flows | –No | Yes | Yes |
| App architecture and module structure | –No | Yes | Yes |
| Offline and sync design | –No | Contributes | Yes |
| Build pipeline, signing and store releases | With support | Yes | Yes |
| Performance work on mid-range devices | With review | Yes | Yes |
| Code review for your team | –No | Yes | Yes |
| Backend or ERP development | Not included | Not included | Not included |
| Product design and UX research | Not included | Not included | Not included |
| Native iOS or Android modules beyond plugin integration | Not included | Case by case | Case by case |
We have backend engineers, designers and QA on other engagements. A Flutter developer billed as any of those would be a disservice to everyone.
Named evidence
Three production apps, with the work named and the duration stated.
A Flutter app for suppliers and customers browsing a jewellery catalog managed in Odoo, over GraphQL, with search, filtering and media served from Cloudflare R2. Running and evolving for 8+ months.
A Flutter Android and iOS app on an Odoo subscription backend with Stripe recurring payments, Google services and vCard export, shipped release over release across 12 to 15 months alongside backend, web, QA and design.
Flutter developers working with Odoo and Next.js engineers on a live remittance product since 2023, shipping payment, agent and wallet features without interrupting live transactions.
How it works
Your app, its backend, what the person would own in the first month, the overlap you need and the start window. An engineer is on the call, not only an account manager.
One or two developers whose recent work is close to your problem, with the apps they shipped and what they did on them. If nobody fits, we tell you.
Your process and your technical exercise. The interview guide below is there to help you run it, not to replace it.
Your repository, branch and review conventions, tracker, standups, and access to a build and a device set so they can ship in the first week rather than the third.
A review with you on productivity, scope and overlap. Problems surfaced in week four are cheap to fix.
They ship in your cadence and your release process, reviewed by your team, with a Heliconia mobile lead available behind them for architecture questions at no extra cost.
The terms
The practical terms, stated before you have to ask for them.
| Question | How we work |
|---|---|
| Engagement model | Full-time or part-time monthly, per developer, with an agreed notice period |
| Time-zone overlap | A stated daily overlap we staff for, rather than a promise of constant availability |
| Whose process | Yours: repository, review rules, tracker, ceremonies and release schedule |
| Store accounts | We work in your Apple and Google accounts under your credentials policy. The apps stay yours |
| Code and IP | Everything written for you is yours, in your repository, from the first commit |
| Security | Least access needed, through your systems, under your policies |
| Replacement | If it is not working, we replace them with a documented handover |
| Knowledge transfer | Documented as they go, so the app survives the engagement |
Store accounts matter more than people expect. An app published under an agency account is a hostage. We do not do that.

What clients say
Heliconia's Odoo Enterprise implementation, along with third-party system integration, has optimized our processes. Their expertise has been a game-changer.

Kartson KrayChairman, TIMmunity GmbHQuestions
Yes, and that is most of this work. WaveContact and Ramdev Kangan are both multi-month ongoing engagements on apps that were already live, shipping releases into existing codebases and store listings.
Enough to be useful, which is the point. They have shipped against GraphQL and REST APIs over Odoo, argued about response shape, and worked beside the engineers building it.
They are not backend developers. If you need work inside the API itself, we would propose the right specialist rather than stretch the mobile one.
Usually a team decision. Flutter gives one Dart codebase and consistent rendering. React Native shares language and often components with a React web team. We staff and build both, so the recommendation is not self-serving.
If the answer turns out to be React Native, we will tell you rather than sell you Flutter.
You do. We work in your Apple and Google accounts under your credential policy, and the listings, reviews and analytics stay yours. An app published under an agency account is a hold over you that nobody should accept.
No. Rates depend on seniority, commitment and duration, and a number without those is meaningless. Tell us the role and the length and you will have a rate on the first call.
Yes. Hiring developers means you own delivery and we supply capacity into your process. A project means we own scope, timeline and result. If you want the outcome rather than the people, start with the service page.
Next step
Send us what the developer would own in their first month, what the app talks to and the overlap you need. You get one or two matched developers with their real app history, and you run your own interview.
