Application engineering
We decide the architecture before we write code and choose the stack for a ten-year life, not a launch demo. Backend, frontend and mobile come from one team working to one design, with the integration to Odoo (or whatever runs your business) planned in from the first week rather than bolted on at the end.

Businesses that run on what we built
How we work
Custom application development at Heliconia means one team designing and building the backend, the web frontend, the mobile app and the integrations of a system as a single architecture, with the decisions that determine whether it can still be changed in five years made first, in writing.
Most custom applications fail slowly: the demo was fast, the architecture was implicit, and every change after launch costs more than the last. We optimise for the opposite curve. Freiburger Bund (an Odoo 18 backend, a Next.js 15 portal, a React Native app and a Socket.IO messaging server) has been in continuous development for over a year without a rewrite, because the boundaries were drawn before the first sprint.
Application services
Portals, dashboards, internal tools and SaaS frontends with real auth, data and business logic.
React Native and Flutter apps for customers, members, suppliers and field teams.
The layer that connects the application to Odoo, payments, CRMs and everything else.
Technical expertise
Web, mobile, backend and infrastructure as one coherent capability, every part in production today.
Also in production
Delivery
Users, workflows, data, the systems it must talk to, and the non-functional requirements (scale, offline, real-time, compliance) that shape the architecture.
Service boundaries, data model, API contract, frontend/mobile split, hosting and the integration plan. Written down and reviewed with you before code.
Repositories, CI, environments, authentication, the API skeleton and the design system. The unglamorous month that makes every later month faster.
Sprints delivering usable slices (backend, web and mobile together) reviewed on staging with real data.
Unit and end-to-end tests (Playwright), load testing where it matters (Artillery), security review on auth and data access.
Production deployment with monitoring and rollback, then continuous delivery under an ongoing engagement.
Reference architecture
The pattern behind Freiburger Bund, WaveContact and our headless commerce builds: clear layers, one API contract, business logic in one place.
Web app
Next.js / React
Mobile app
React Native / Flutter
External systems
Payments, CRM, email, partners
API layer
GraphQL / REST · authentication · webhooks · queues
Application services
Node.js / Python services, real-time server, background jobs, and Odoo when it's the system of record
Data and infrastructure
PostgreSQL · Redis · Meilisearch · object storage · Docker on cloud or on-premise
Evidence
Healthcare association & career portal
A medical association platform where Odoo 18 Enterprise is the business backend behind a Next.js 15 web portal, React Native (Expo) iOS/Android apps, a Socket.IO messaging server and MeiliSearch: in German, English, French and Arabic.
SaaS: digital business cards
Digital profile and contact-sharing platform where Odoo runs subscriptions, orders and the store behind a web frontend and a Flutter mobile app, with Stripe recurring payments, Google integrations and vCard export.
Alloy casting & foundry manufacturing
Multi-stage alloy casting (molding, pouring, heat treatment, NDT, machining) on Odoo 16 Community, with furnace heat numbers traced to every dispatched part, a metallurgy lab module and Material Test Reports generated in seconds.
What clients say
Heliconia provided a unique canteen solution, saving us valuable ordering time. Their innovative approach has been invaluable to our operations.
Pradeep LakhaniBusiness Owner, Avasar AgencyHeliconia transformed our business with Odoo. They implemented a dynamic website with e-commerce capabilities, enhancing our online presence significantly.

Discovery, written architecture, a foundations phase (repos, CI, auth, API skeleton), iterative sprints delivering usable slices across backend, web and mobile, automated testing, then release with monitoring and an ongoing engagement.
All of them, as one architecture, by one team, and we're happy to build one layer against your existing ones when that is what you need.
Integration is part of the architecture, not an afterthought: an API layer with retries, idempotency and monitoring, and Odoo (or your CRM, payments, logistics) treated as a first-class service in the design.
TypeScript/Node.js and Python on the backend, PostgreSQL, Next.js/React on the web, React Native and Flutter on mobile, GraphQL and REST APIs, with Redis, Meilisearch and S3-compatible storage where needed. Only what we run in production.
Yes: an MVP on the same architecture, so it grows into the product instead of being thrown away. The foundations phase is what makes that possible.
No. Odoo development extends Odoo with modules. Custom application development builds standalone applications, which very often integrate with Odoo.

Tell us what it must do, who uses it and what it must connect to. We'll come back with an architecture sketch, a stack recommendation and a phased plan.
