Everything users see depends on what they don’t.
A slow API, a fragile integration or a database that cannot grow will hold back even the best interface or AI model. Backend decisions made early are expensive to undo later.
We design the architecture around how your product will actually be used, write APIs that are documented and tested, and set up the infrastructure to deploy, monitor and scale it with confidence.
- REST & GraphQL APIs (FastAPI, Node.js)
- PostgreSQL & MongoDB databases
- Authentication & authorization
- Microservices architecture
- Message queues & background jobs
- API gateway & rate limiting
Backend Development services
Pick one piece or the whole stack — every engagement is scoped to what your product needs.
REST & GraphQL APIs
Well-documented, versioned APIs in FastAPI or Node.js with clear contracts for every client.
Database design
PostgreSQL and MongoDB schemas, indexes and migrations designed for correctness and growth.
Authentication & access control
Secure sign-in, roles and permissions with OAuth, JWT, Cognito or your identity provider.
Microservices
Services split along real boundaries, communicating through APIs and message queues.
Background jobs & queues
Celery, Redis and queue-based workers for emails, reports, AI tasks and scheduled work.
Third-party integrations
Payments, CRMs, messaging, webhooks and internal systems connected reliably.
Our approach to Backend Development.
A clear sequence, agreed up front, so you always know what happens next and why.
Map the data, users and traffic the system must support
Design the architecture, data model and API contracts
Build endpoints with validation, error handling and logging
Write automated tests for business logic and every endpoint
Containerise and set up CI/CD for repeatable deployments
Add monitoring, alerts and documentation before handover
Ready to scale
Caching, indexing and async processing planned in, so growth does not mean a rewrite.
Secure by default
Authentication, input validation and least-privilege access built into every endpoint.
Easy to hand over
OpenAPI docs, tests and runbooks so your own team can extend it with confidence.
What our backend work covers
API design
Consistent resource naming, pagination, versioning and error formats.
Performance tuning
Query optimisation, caching layers and profiling of slow paths.
Rate limiting & gateways
Protect services from abuse and spikes with gateways and quotas.
Real-time features
WebSockets and event streams for live updates and notifications.
Cloud deployment
Docker-based deployments on AWS, GCP or your own servers.
Observability
Structured logs, metrics and alerts so issues are found before users report them.
From first call to production.
Weekly demos, clear milestones and access to the code from day one.
Discover
We dig into your problem, goals, data and existing systems before proposing anything.
Architect
We design the AI stack, database schema, API structure and interface, then agree scope and timeline.
Build
Focused sprints covering backend, AI models and frontend together — with a demo every week.
Deploy
We ship to production with CI/CD, monitoring and documentation, then hand everything over.
Backend Development: common questions.
Can’t find your answer? Ask us directly — we reply within 24 hours.
FastAPI or Node.js — which do you recommend?
FastAPI is our default when the product involves AI, data or Python libraries. Node.js fits well for real-time features or teams already working in JavaScript. We pick based on your product and team, not habit.
Can you take over an existing backend?
Yes. We start with a code and architecture review, document what exists, fix the riskiest issues first and then continue development.
Do you handle hosting and DevOps?
Yes — containerisation, CI/CD pipelines, cloud setup, monitoring and backups, or a handover to your own infrastructure team.
Will we own the code?
Yes. Code, infrastructure configuration and documentation are yours, with no proprietary lock-in.
