Powerful APIs & Server Infrastructure That Scale
MetaLabs Tech builds the server-side foundations that power your product — from RESTful APIs and GraphQL services to databases, authentication systems and cloud-ready microservices.
The Engine Behind Every Great Product
We build the server-side systems your frontend relies on — from high-performance APIs to robust databases, authentication and third-party integrations.
REST & GraphQL APIs
Scalable, well-documented APIs designed for performance — with proper versioning, rate limiting, error handling and full OpenAPI specs.
- RESTful & GraphQL endpoints
- OpenAPI / Swagger docs
- Rate limiting & pagination
Database Architecture
Schema design, query optimisation and migration strategies for SQL and NoSQL databases — built to handle your data at any scale.
- PostgreSQL & MySQL design
- MongoDB & NoSQL
- Migrations & indexing
Authentication & Security
JWT, OAuth 2.0, session management, RBAC and API key systems — built with security best practices from the ground up.
- JWT & OAuth 2.0
- Role-based access control
- API key management
Third-Party Integrations
Stripe, Twilio, SendGrid, Slack, Zapier and hundreds of other services — connected cleanly to your platform with proper error handling.
- Payment gateways
- Email & SMS services
- Webhook handling
Microservices & Queues
Event-driven architectures, message queues and microservices that decouple your systems and keep everything fast under load.
- Redis & BullMQ queues
- Event-driven architecture
- Microservice design
Cloud & Serverless
Serverless functions, cloud-native deployments and containerised back-ends — configured to scale automatically with your traffic.
- AWS Lambda & Edge functions
- Docker & containerisation
- Auto-scaling configuration
Why Teams Trust Us With Their Server-Side
Back-end code is invisible to users but foundational to everything. We build it with the same care as the frontend — clean architecture, documented APIs and zero shortcuts.
- Monolithic codebase hard to scale
- No API documentation
- Passwords stored in plaintext
- Single point of failure
- Clean, modular architecture
- Full OpenAPI documentation
- Security-first from day one
- Horizontally scalable services
API-First Design
We design the API contract before writing a single line of server code — with endpoint specs, response shapes and error codes agreed upfront so frontend and back-end never block each other.
Performance Under Load
We profile slow queries, add proper indexing, implement caching with Redis and design for horizontal scaling — so your API stays fast as your user base grows.
Security by Default
Input validation, parameterised queries, encrypted secrets, HTTPS enforcement and regular dependency audits — security is baked in, not bolted on after launch.
Code You Can Own
Clean, well-commented code with a logical folder structure — so your in-house team can pick it up, extend it and maintain it without needing us in the room.

Security Incidents
From Requirements to Running in Production
A structured process that turns business requirements into clean, tested and well-documented back-end systems — delivered on schedule.
Requirements & API Design
We map out every endpoint, data model, authentication flow and integration needed — producing an API spec before any code is written.
1–3 daysDatabase & Architecture
Schema design, indexing strategy, caching layers and infrastructure decisions — all reviewed before development begins.
2–4 daysDevelopment & Integration
We build endpoints, business logic, auth systems and third-party integrations iteratively — with working builds shared throughout.
2–5 weeksTesting & Security Audit
Unit tests, integration tests, load testing and a security review — covering injection, auth flaws and exposed endpoints.
3–5 daysDeploy & Monitor
CI/CD pipeline, containerised deployment, uptime monitoring, error tracking and documentation handoff — then we remain on standby.
1–2 daysBack-End Tools & Frameworks
We choose the right back-end stack for your project's scale, team and long-term needs — not just the trendiest tool of the year.
Languages & Runtimes
The core back-end languages we build production systems in.
Frameworks & APIs
Proven frameworks for REST, GraphQL and real-time APIs.
Databases
Relational, document and in-memory data layers.
Auth & Security
Identity, access control and secrets management.
Queues & Messaging
Async processing and event-driven architectures.
Deployment & Infra
Cloud and container tooling for production-ready deployments.
Back-End Development Questions
Common questions about our back-end development services, API design and server infrastructure.
It depends on your use case and team. For most APIs and web apps we default to Node.js with Express or NestJS — fast to build, easy to hire for and excellent for real-time features. For data-heavy or ML-adjacent projects we lean toward Python with FastAPI. For high-throughput services we consider Go. We'll recommend the right stack after understanding your requirements.
Yes. Whether your frontend is React, Next.js, a mobile app or a third-party platform, we'll design an API layer that integrates cleanly — with the right authentication, response shapes and documentation so your frontend team can work against it independently.
We implement JWT-based auth for stateless APIs, OAuth 2.0 for social logins, and session-based auth for traditional web apps. For role-based access control we design permission systems tailored to your user types. If you already use Auth0 or Firebase Auth, we can integrate with those too.
Always. We generate OpenAPI (Swagger) specs for every REST API and provide an interactive documentation interface so your frontend team, QA team or third-party developers can explore and test endpoints without needing to ask us for details.
We design for horizontal scaling from the start — stateless API servers, database connection pooling, Redis caching for hot data and message queues for async workloads. We also load-test before launch to validate that the system performs under realistic traffic volumes.
Yes. We regularly perform back-end audits — reviewing existing codebases for security vulnerabilities, N+1 query problems, missing validation and architectural issues — then refactor incrementally so existing functionality is never disrupted.
Yes. We offer retainer-based maintenance covering dependency updates, security patches, performance monitoring, bug fixes and feature additions — so your back-end stays healthy and up to date long after the initial build.
Let's Build a Back-End Your Product Can Rely On
Whether you need an API from scratch, a database redesign or someone to take over a legacy codebase — let's talk about what you're building and how we can make the server-side rock-solid.
