What we build

From a first marketing page to the platform your business runs on, every engagement uses the same senior team, the same standards and the same obsession with how it performs in the real world.

Solutions
Every build starts with the outcome it has to produce.
Most software problems aren't really code problems — they're process, scale or experience problems. These are the situations teams bring to Indexix, and the shape the work takes in response.
01 / 06For founders & product teams
Launch a New Digital Product
For teams with an idea and no codebase yet. Scope, design and engineering run as one process from concept to production — and the v1 is structured to be extended, not thrown away.

Extend an Existing Product
Add capability, modernize the parts that slow you down and improve performance inside the existing product. A staged plan that protects what already works instead of restarting it.

Process
From first conversation to a product that scales.
Every engagement moves through the same seven stages. Each one produces a defined output, so scope, progress and what comes next stay clear at every stage.
- 01
Discover
Understand the business, its goals, its users and the problem genuinely worth solving — before any scope is committed.
- 02
Plan
Define scope, priorities, technical architecture and a delivery roadmap with milestones you can hold us to.
- 03
Design
Resolve the user experience, interface and visual direction in design, so engineering builds against a clear target.
- 04
Build
Develop on a modern, scalable stack in reviewable increments, with automated checks running on every change.
- 05
Test & Refine
Verify functionality, responsiveness, performance and usability against real conditions, then refine what needs it.
- 06
Launch
Deploy to production with monitoring in place, and confirm every critical path works before handover.
- 07
Scale
Keep improving — new features, performance work and infrastructure that expands with the business.
Technology
Technology chosen to fit the product, not the trend.
A focused, modern stack chosen for how it holds up in production — mature tools with strong ecosystems, applied only where they fit the requirements.
01
Frontend
Fast, accessible interfaces built on a component architecture that stays maintainable as the product grows.
- Next.js
- React
- TypeScript
- Tailwind CSS
02
Backend & APIs
Well-structured services and APIs, with authentication and clear boundaries between concerns.

- REST APIs
- Authentication
- Server-side architecture
03
Databases & Infrastructure
Data models designed around real access patterns, deployed on infrastructure sized to the load.
- PostgreSQL
- Database architecture
- Cloud infrastructure
- Deployment
04
SaaS & Product Engineering
The platform layer a SaaS product depends on — tenancy, access control, billing and integrations — built once, properly.
- Multi-tenant architecture
- Authentication
- Billing
- Dashboards
- Role-based access
- Integrations
05
Mobile
One codebase for iOS and Android, with platform conventions respected where they matter.
- React Native
- iOS

06
Engineering
The practices that keep a codebase shippable — tests, performance budgets, security review and a responsive architecture.
- Performance

Why Indexix
We don't just build software that works — we build what the business runs on.
Every engagement is shaped around the business, the people who use the product, and the requirements it will grow into. Serious engineering, a team you work with directly, and a build that holds up long after launch.
01
Business First
Every technical decision traces back to a business outcome. Scope, architecture and priorities start there.
02
Built to Scale
Architecture that fits the product today and doesn't have to be torn out when usage, data or the team grows.
03
Quality by Default
Performance, accessibility, security and maintainability are written into the build — not booked as later work.
04
Long-Term Partnership
The relationship can continue past launch: maintaining, improving and scaling the product as priorities change.
