Wellness Brand Backend Development
Hands-on backend help for a global wellness products company whose existing application needed experienced developers.
Business goals
The client is a wellness products company selling across international markets. Its backend application sits behind everyday business activity, and the work on it needed more experienced hands. The client wasn't looking to replace the system or start over. It wanted developers who could read an application they hadn't written, make changes carefully, and leave the code in better order while the business kept trading.
Project overview
Hexagon provided backend application help to the client. Our developers worked inside the existing application, not around it. We learned how it was structured, handled backend changes and fixes, and worked within the client's way of releasing code. The work was deliberately focused. It added backend capacity to the client's team, with no new product launch or rebuild attached to it.
Challenges faced and solved
Joining a live backend is a different job from starting one from scratch.
Code nobody new has seen
Backend systems at consumer brands build up years of decisions, and few of them are written down. A new developer who guesses at intent can break something a customer depends on.
We started by reading the code and tracing how requests move through it, then confirmed our understanding before changing anything.
Changing a system that can't stop
Product and customer activity doesn't pause while a developer works. A backend release that goes wrong reaches shoppers and staff straight away, in every market the application serves.
We made small, reviewable changes in version control and tested them before release, so each change could be understood and reversed.
Too few backend hands
Internal teams at growing product companies tend to spend their days on urgent requests. Backend improvements get pushed back again and again, and the list of known issues keeps growing.
We added backend capacity alongside the client's people, taking on assigned work so their team could keep up with its other priorities.
Keeping knowledge in-house
Outside developers can leave a system harder to maintain if their work follows private habits. Once they finish, the internal team inherits code it doesn't fully understand or want to touch.
We followed the conventions already in the application and kept our work in the client's repository, so the code stayed theirs to maintain.
Features
| Feature | Description |
|---|---|
| For the client's development team | |
| 1. Backend Fixes | Defects in server-side code were traced to their cause and corrected, so the same issue is less likely to come back. |
| 2. Backend Feature Changes | New business requests were added to the existing application without disturbing what already worked. |
| 3. API Work | Backend REST APIs were built or adjusted so other parts of the system could request the data they needed. |
| 4. Code Review Ready Changes | Work was delivered in small units through Git and GitHub, so the client's team could see exactly what changed. |
| For the business | |
| 5. Data Handling | Server-side logic that stores and retrieves business records was corrected or extended as needs came up. |
| 6. Application Performance Checks | Slow backend operations could be located and looked at, because staff and customers feel delays first. |
| 7. Stable Releases | Changes moved through testing before they went live, which lowers the chance of a disruption. |
| 8. Technical Notes | Findings about how the application behaves were shared, so knowledge did not leave with the developer. |
How the platform is put together
Each layer has one job.
The result
The client had additional backend developers working in its existing application, without starting a rebuild.
| Area | Before | After |
|---|---|---|
| Backend capacity | Limited to what the internal team could fit in | Outside developers working on assigned backend items |
| System continuity | Any larger change risked touching a live system | Small changes inside the existing application |
| Change history | Depends on who remembered the last change | Work tracked and reviewable in version control |
| Ownership of the code | Risk of work only one vendor understands | Code kept in the client's own conventions |
How we took it from idea to launch
Good software follows a process. Here are the six stages, and what happens in each one.
Discovery & Requirements
Goal: Define the product vision, target audience and core business requirements.
Key activities- Stakeholder interviews
- Market and competitor research
- Defining user personas
- Drafting technical specifications or a Product Requirements Document (PRD)
Design (UX / UI)
Goal: Create an intuitive user experience and visual interface.
Key activities- UX design: information architecture, user flows and wireframes
- UI design: high-fidelity mockups and interactive prototypes in Figma or similar tools
- Design system: colors, typography and component libraries
Development: Frontend & Backend
Goal: Build the functional application using agile sprints.
Key activities- Backend: set up databases, design APIs (REST, GraphQL), implement server logic, and configure authentication and authorization (OAuth, RBAC)
- Frontend: build responsive interfaces and connect components to backend APIs
- Version control: manage code through Git and GitHub
Security & Optimization
Goal: Harden the application against vulnerabilities and boost performance.
Key activities- Security: address the OWASP Top 10, including injection, XSS and CSRF, enforce encryption in transit and at rest, and implement rate limiting
- Optimization: code splitting and lazy loading, database indexing, API caching and load testing
- QA and testing: unit, integration and end-to-end tests
Beta Release
Goal: Deploy to a controlled group of real users to catch edge-case bugs and gather feedback.
Key activities- Set up staging and production CI/CD pipelines
- Launch a closed or open beta with real users
- Monitor errors through observability tools
Public Release (Launch)
Goal: Roll the software out to the general public.
Key activities- Final production deployment
- DNS configuration
- Marketing and onboarding rollout
- Post-launch performance and security monitoring
Business benefits
A company can add backend skills for a defined need without a long hiring process.
The current application keeps doing its job while it gets better.
Small tested changes are easier to check and to roll back.
Following existing patterns means the internal team can carry on after the engagement.
Conclusion
Not every software project is a new platform. Sometimes a company has a working application and simply needs capable backend developers who can learn it quickly and make careful changes. That is what Hexagon provided here for a wellness products company with customers around the world. The engagement was small by design, and it stayed that way.
