APIs serving millions of requests.

Backend Systems Built to Scale

Robust APIs, scalable architectures, and backend systems that power your applications reliably—from launch day to millions of users.

The Foundation Everything Depends On

Your backend is the foundation everything else depends on. It needs to be fast, secure, and reliable. It needs to scale when you grow and not break when traffic spikes. It needs to be maintainable by your team long after launch. At Rubrec, we design and build backend systems with production realities in mind. We're not just writing code—we're architecting for performance, security, and longevity. From RESTful APIs to event-driven microservices, we build backends that work.

What We Build

Scalable systems and APIs that power your applications reliably.

RESTful & GraphQL APIs

Clean, well-documented APIs that your frontend, mobile apps, and third-party integrations can rely on. Consistent patterns, proper error handling, and comprehensive documentation.

Microservices Architecture

Distributed systems designed for scale and resilience. Service boundaries that make sense, communication patterns that work, and observability built in.

Serverless & Edge Functions

Lightweight, scalable functions that run on-demand. Cost-efficient solutions for specific tasks without managing infrastructure.

Real-Time Systems

WebSocket implementations, event streaming, and push architectures for applications that need instant updates.

Data Processing Pipelines

ETL workflows, batch processing, and data transformation systems that handle volume without breaking.

Third-Party Integrations

Payment processors, CRMs, ERPs, and external APIs. We build integrations that are robust, handle edge cases, and fail gracefully.

Database Design & Optimization

Schema design, query optimization, indexing strategies, and migrations. Databases that perform at scale and evolve with your product.

Background Jobs & Scheduling

Cron jobs, task queues, and async processing. Offload heavy work from your main application without losing reliability or visibility.

Our Approach

A structured process that delivers reliable, production-ready backend systems.

Discovery

Understanding your data model, scale requirements, and integration landscape. What systems exist? What are the performance targets? Where are the risks?

Architecture Design

Before coding, we design. Data models, API contracts, service boundaries, and infrastructure decisions—documented and validated.

Development

Test-driven development, continuous integration, and iterative delivery. We ship working software frequently, not everything at once.

Launch & Beyond

Load testing, security audits, deployment automation, and monitoring setup. We make sure your backend performs in production.

Selected Works

Real projects, real results. From global retail brands to healthcare platforms serving thousands of patients, here's a glimpse into the work we've delivered—and the impact it created.

Why Rubrec for Backend

What sets our backend development apart from the rest.

Production Mindset

We think about monitoring, error handling, and failure modes from day one—not after the first outage.

Scalability by Design

We architect for your next stage of growth, not just today's requirements.

Security Built-In

Authentication, authorization, input validation, and security best practices are standard, not optional.

Documentation Culture

APIs ship with proper documentation. Your team (and future developers) will thank us.
