What We Build

The backend is the invisible half of every great app. Elmeris designs and builds the server-side infrastructure that keeps your mobile and web applications fast, reliable, and secure at any scale.

REST & GraphQL APIs

Documented, versioned APIs with authentication, rate limiting, and consistent error handling.

Database Design

Relational (PostgreSQL, SQL Server) and NoSQL (MongoDB, Firestore) schema design and query optimisation.

Authentication & Authorisation

JWT, OAuth 2.0, API keys, and role-based access control — secure by default.

Cloud Infrastructure

Infrastructure-as-code on AWS, GCP, or Azure with auto-scaling, backups, and monitoring.

Serverless & Functions

Event-driven architecture using AWS Lambda, Azure Functions, or Google Cloud Functions for cost-efficient workloads.

Background Jobs & Queues

Reliable task queues, cron jobs, and event processing for async workloads.

Technologies

We choose the right tool for each project. Our backend expertise spans multiple languages and cloud platforms:

Security by Default

Every API and backend system we build is reviewed against the OWASP Top 10. We apply security best practices at every layer — input validation, parameterised queries, secrets management, HTTPS-only endpoints, and least-privilege access control.

How We Work

Architecture

Define data models, API contracts, cloud services, and security requirements before development.

Development

Iterative backend development with comprehensive test coverage and API documentation.

Infrastructure

Cloud environment setup with CI/CD pipelines, environment parity, and infrastructure-as-code.

Operations

Monitoring, alerting, log aggregation, and on-call runbooks for production readiness.
