Backend & API Development Services
Production-ready backend and API development for scalable products.
What we build
Application backends
Business logic, data models, and services that power web and mobile products.
Public & private APIs
Well-structured APIs for frontend apps, integrations, and partner systems.
Authentication & authorization systems
Secure access control, roles, permissions, and identity flows.
Integrations & data flows
Connecting third-party services, internal systems, and external platforms.
Our approach to backend engineering
We design backend systems before writing code.
Clear domain and data modelling
We define data structures, business logic, and system boundaries upfront — not during implementation.
APIs designed around real usage patterns
API design follows actual usage patterns and client needs, not theoretical ideals.
Separation of concerns for long-term maintainability
Clear boundaries between services, layers, and responsibilities to keep systems understandable.
Error handling, logging, and monitoring built in
Observability and error handling are built into the architecture from the start, not added later.
This prevents fragile systems that break as features and teams grow.
Built for reliability and change
Backends must handle change without becoming unstable.
This allows products to evolve without constant firefighting.
Technology & stack
Technologies are selected for stability, performance, and supportability.
When this service is a good fit
Backend & API Development is ideal when:
Your product logic is becoming complex
Multiple clients (web, mobile, partners) need to share data
Security, permissions, or compliance matter
Existing backend systems need restructuring or extension
Outcomes teams typically achieve
How we work
A clear path from idea to production-ready software
Clear scope. Predictable delivery. No surprises.
Define the system
Domain logic, data models, API contracts, and scope.
Build & integrate
Implementation, integrations, testing, and documentation.
Stabilise & scale
Performance tuning, monitoring, and long-term evolution.
Frequently asked questions
Yes. We often extend, refactor, or stabilise existing backend systems without disrupting users.
Yes. API contracts and system behaviour are documented to support internal teams and integrations.
You do. All code, repositories, and environments remain fully under your ownership.
Very simple:
Tell us what you're building — we'll help you design, launch, and scale it.
H-Studio provides backend and API development services for companies building secure, scalable backend systems. We design and build backend systems and APIs that reliably support web and mobile products — handling data, logic, integrations, and scale behind the scenes. Our backend engineering approach focuses on designing systems before writing code. We establish clear domain and data modelling, design APIs around real usage patterns, and build in error handling, logging, and monitoring from the start. This prevents fragile systems that break as features and teams grow.
