Robust API & Backend Engineering Built for Scale
API & Backend Development
Robust APIs and Backends That Power Your Product
We design and build secure, scalable backend systems and APIs that quietly power your apps, workflows, and integrations — so your product feels fast and reliable, no matter how much you grow.
What We Build
- RESTful and GraphQL APIs for web & mobile apps
- Backend services and microservice-style architectures
- Authentication, authorisation & role-based access control
- Integration layers between products, tools & third-party systems
- Background jobs, schedulers and event-driven processing
Where It Helps Most
- Products needing reliable APIs across web, mobile and internal tools
- Businesses replacing fragile spreadsheets with proper systems
- Teams standardising data flows across CRMs, ERPs and SaaS tools
- Organisations preparing for higher scale, more traffic, or new features
API-First Architecture
We design your system around clear, well-documented APIs so multiple products, services and teams can plug into the same stable backbone.
- REST and GraphQL API design
- Versioning and backwards compatibility
- API documentation and onboarding support
Secure & Reliable Backends
Security and reliability are built in from the start — from proper authentication and input validation to logging, monitoring and fallbacks.
- Auth, RBAC and token-based access
- Input validation and rate limiting
- Error handling, logging and alerting hooks
Integrations & Data Flows
Your backend doesn’t live in isolation. We build integration layers that connect your product with payment gateways, CRMs, ERPs and other tools you already use.
- 3rd-party API integrations and webhooks
- Data sync between internal and external systems
- Batch, real-time and event-driven workflows
Scalability & Performance
As traffic grows, your backend should keep up without becoming a bottleneck. We plan for scale with caching, queues and smart architecture choices.
- Caching strategies (Redis, in-memory, response caching)
- Queues and background processing
- Horizontal scale and cloud-native patterns
Modern Tech Stack
We work with modern, widely adopted backend ecosystems that are easy to evolve and support over time — not obscure, one-off frameworks.
- Node.js, PHP, Python, Go and modern frameworks
- MySQL, PostgreSQL, MongoDB and other data stores
- Docker, Kubernetes and cloud-native deployments
Built for Real Development Teams
We don’t just ship code and disappear. We document, structure and package backends so your team (or ours) can maintain and extend them confidently.
- Clean project structure and conventions
- Environment setup and configuration guidelines
- Handovers and ongoing collaboration options
Use Cases
Where a Strong Backend Makes the Difference
A well-designed backend quietly improves everything: speed, stability, user experience and your team’s ability to build on top of it.
Multi-Channel Product
One backend powering web apps, mobile apps and internal tools with consistent APIs.
System Modernisation
Wrapping or replacing legacy systems with stable APIs, without a risky “big bang” rewrite.
Operational Automation
Automating repetitive operations and syncing data between CRMs, ERPs and internal tools.
Data & Reporting
Centralising data flows and exposing reporting endpoints for dashboards and BI tools.
How We Work
From Architecture to Live APIs — Done Collaboratively
We keep you involved at every step, with clear decisions around architecture, security and delivery so you always know how your backend is evolving.
Understand Your Flows
We map out your existing tools, data sources, user journeys and integration points.
Design the Architecture
We define services, APIs, databases and scaling strategy aligned with your roadmap.
Build, Secure & Test
We implement, secure and test endpoints, with environments ready for your team to use.
Launch & Evolve
We support go-live, monitor behaviour and refine as traffic and use-cases grow.
Why Trust ByteBlock with Your Backend?
Backends are where reliability, security and long-term maintainability really matter. We build with a mix of strong engineering practice, pragmatic decisions and clear communication — so your team always knows how things work under the hood.
We always start from architecture, not just “coding the feature” in isolation.
Security, logging and error handling are part of the baseline, not bolt-ons.
Clear patterns and documentation that make it easier to add new features later.
