Our Backend Development Services
From API design to database architecture — we build backends that are secure, maintainable, and built to scale.
REST & GraphQL APIs
Well-documented, versioned APIs built for scale — RESTful endpoints, GraphQL schemas, and gRPC services tailored to your product.
Microservices Architecture
Decompose monoliths into independently deployable services — with event-driven communication, service meshes, and clean domain boundaries.
Database Design & Optimisation
Schema design, indexing strategies, query optimisation, and migrations — MySQL, PostgreSQL, MongoDB, and Redis, tuned for your data patterns.
Authentication & Security
JWT, OAuth 2.0, SSO, and role-based access control — security-first design that protects your users and your data from day one.
Third-Party Integrations
Payment gateways, CRMs, ERPs, shipping APIs, and more — clean integration layers that keep your core logic separate from vendor dependencies.
Performance & Scalability
Caching strategies, load balancing, horizontal scaling, and profiling — so your backend handles 10x traffic without breaking a sweat.
How We Work
A structured, transparent process that moves from requirements to production without surprises.
Requirements & Scoping
We map your business logic, data flows, and integration points before writing a single line.
Architecture Design
System diagrams, data models, and API contracts reviewed and signed off before build starts.
Development & Testing
Clean, documented code with unit, integration, and load tests — no shortcuts before staging.
CI/CD & Deployment
Automated pipelines, zero-downtime deploys, Docker containers, and infrastructure as code.
Monitoring & Handover
Logging, alerting, and dashboards set up — full documentation and knowledge transfer on completion.

What Our Clients & Partners Say
Agencies and engineering leaders who trusted us to build their backend infrastructure.
“DevriX rebuilt our entire API layer in four months. Response times dropped from 800ms to under 60ms. The architecture they designed is still serving us two years later without a single major incident.”
“We went from 10k to 1 million users in eight months. DevriX had the backend scaled and stable before we even hit the growth spike. Their microservices design saved us from a complete rewrite at scale.”
“The payment API they built handles $2M+ daily volume with zero downtime. PCI compliance was baked in from day one, not retrofitted. Exactly the backend partner we were looking for.”
Technologies We Work With
Battle-tested backend technologies chosen for performance, reliability, and long-term maintainability.
Frequently Asked Questions
What backend frameworks do you specialise in?
Our primary stack is Laravel (PHP), Node.js with Express or NestJS, and Python with FastAPI or Django. We recommend the right framework for your use case — performance requirements, team expertise, and long-term maintainability all factor into the decision.
How do you design and secure APIs?
We follow API-first design — defining contracts, schemas, and versioning strategy before coding. Security is baked in: OAuth 2.0, JWT, rate limiting, input validation, and OWASP Top 10 mitigations are standard, not optional.
Can you integrate with our existing systems or third-party services?
Yes. We regularly integrate with payment gateways, CRMs, ERPs, shipping providers, communication APIs, and custom legacy systems. We build clean integration layers so your core business logic stays decoupled from vendor dependencies.
Which database should we use — SQL or NoSQL?
It depends on your data structure and access patterns. We recommend PostgreSQL or MySQL for relational data with complex queries, MongoDB for flexible document structures, and Redis for caching and real-time operations. Most production systems use a combination.
How do you handle scalability and high traffic?
We design for horizontal scale from the start — stateless services, database connection pooling, caching layers, and load balancing. Before launch we run load tests to validate the system handles projected peak traffic with headroom.
What does your CI/CD setup look like?
We set up automated pipelines on GitHub Actions or GitLab CI — lint, test, build, and deploy on every push. Production deployments are zero-downtime with blue-green or rolling strategies, and we include rollback procedures.
How long does a typical backend project take?
A standalone API or integration is typically 3–6 weeks. A full backend architecture with database design, auth, and CI/CD is 6–12 weeks depending on scope. We scope it precisely in the first technical call.
Do you provide monitoring and ongoing support after launch?
Yes. We set up logging, error tracking, and performance monitoring (Datadog, Sentry, CloudWatch) before handoff. Post-launch support retainers include incident response, dependency updates, and ongoing feature development.
