System Architecture & Operations

Systems that scale,
survive, and serve.

We design, build, and operate high-performance software systems. From day one, we bake in observability, security, and the ability to evolve.

Our Engineering Spectrum

We focus deeply on three core layers of modern software architecture.

Product Surface

The touchpoints where users interact with value.

Next.js ApplicationsMobile (React Native)Voice InterfacesAdmin Panels

Core Backend

The business logic, safety, and orchestration engine.

MicroservicesGraphQL / RESTWorkflow EnginesAuth & Identity

Data & Intelligence

Where information is stored, processed, and enriched.

PostgreSQL ClustersVector StoresEvent StreamsLLM Pipelines

Anatomy of a Marquelabs System

We believe in explicit boundaries. Every system is composed of decoupled layers that can scale independently and fail without cascading.

Frontend

Responsive interfaces built with Next.js or React Native. Optimised for Core Web Vitals.

Services

Stateless application logic. Scalable horizontally. Written in Node.js, Go, or Python.

Data

Managed databases with automated backups and point-in-time recovery.

AI

Context-aware agents integrated via queues to prevent latency spikes.

Security

Zero-trust networking, encrypted secrets, and automated vulnerability scanning.

Built for Day 2 Operations

It's not enough to just ship. We build systems that are easy to debug, easy to fix, and safe to update.

Reliability & SLOs
We define clear Service Level Objectives for latency and availability. Alerts only fire when these objectives are threatened.
  • Automated Health Checks
  • Error Budget Tracking
  • PagerDuty Integration

> error_rate: 0.01%
Safe Deployment Environments
No cowboy coding. We implement strict GitOps workflows with mirrored staging and production environments.

Security First
Least privilege access, encrypted at rest, and regular audit logs.
Observability
Full tracing from frontend click to database query.
