MDS Website
A statically generated Next.js platform with a typed content registry, a portfolio media system and a validated inquiry flow.
Service 03
Custom Software
Software engineered for the way your business works.
Web platforms, internal tools, backend services, APIs and AI-enabled products — built when an existing product cannot do the job, or when the software is the product.
Schematic
You need this if
Off-the-shelf tools no longer fit, your process lives in spreadsheets, or you are building a product of your own.
01Who it is for
Founders building a product
From a validated idea to a first release that real users can rely on, with an architecture that can grow.
Businesses outgrowing spreadsheets and SaaS
When the workarounds have become the process and the tools cost more in time than they save.
Teams that need an engineering partner
Companies with a product team but not the backend, integration or AI capacity a project needs.
02Problems it solves
- 01
Workarounds have become the process
Exports, imports and manual checks hold together tools that were never designed for your workflow.
- 02
Systems do not share data
Each department has its own version of the truth, and reconciling them is somebody's job.
- 03
A product idea without an engineering team
The opportunity is clear, but turning it into reliable, secure software needs a team you do not have yet.
- 04
Legacy software slows every change
Small requests take weeks because nobody is confident about what will break.
03Example use cases
Web applications
Browser-based products and portals for customers, partners or staff.
Mobile applications
iOS and Android apps that share a backend with your web platform.
Custom business platforms
Systems that encode how your business quotes, schedules, delivers and bills.
Backend services
Business logic, background jobs and services designed for reliability and change.
API development
Documented APIs for your products, partners and integrations.
Database systems
Data models, migrations and reporting structures that stay coherent as you grow.
SaaS applications
Multi-tenant products with accounts, billing, roles and administration.
AI-enabled products
AI features designed into the product — evaluated, monitored and cost-controlled.

05How we implement it
Scope
Agree the problem, the users and the smallest release that proves value.
Architect
Choose the stack and design the data model with the next two years in mind.
Build in increments
Working software every few weeks, reviewed in a real environment.
Release and support
Launch with monitoring, then improve based on how it is used.
When we will advise you not to build
- A mature product already covers most of what you need and the rest can be configured or integrated.
- The process itself is still changing — software would freeze a workflow that is not settled.
- Nobody can own it after launch. Custom software is an asset that needs maintenance.
- In those cases we recommend the existing product and, where useful, integrate it properly.

All projects07Questions
Which technologies do you use?
We choose the stack to fit your team, scale and constraints. For most web products that means TypeScript with React and Next.js, Node.js services and PostgreSQL. Where we recommend something else, we explain why.
Who owns the code?
Ownership and licensing are agreed in writing before work starts. We recommend that repositories and production infrastructure live in accounts you control.
Can you take over an existing codebase?
After a technical review. We assess code quality, dependencies, security and deployment, then propose whether to stabilise, refactor or rebuild specific parts.
Do you maintain software after launch?
Support is scoped separately — monitoring, updates, security patches and improvements — so it is clear what is covered and what is not.
