What We Build

Built for real operations, not template websites.

520.ie delivers running business systems. We design product, backend, data, integrations, and operations on the same engineering map so the system can be handed over, measured, and improved from day one.

Internet Product Engineering

We build durable product systems for SaaS platforms, client portals, mobile applications, and operational back offices.

Product UX and prototyping
Multi-tenant access models
Admin consoles and dashboards

FinTech Systems

We design monitored and auditable toolchains around market data, account integrations, research workflows, risk rules, and execution support.

Market and account APIs
Quant research tooling
Risk and audit workflows

Cloud Native Delivery

From repository to production, we establish automated testing, deployment, monitoring, alerting, and rollback paths.

Docker containerization
CI/CD pipelines
Logs, metrics, and alerts

Operating Model

Complex systems should be manageable, auditable, and ready to evolve.

The hard part of FinTech and internet systems is not only writing code. It is keeping data, integrations, permissions, risk controls, and deployments clear as the business changes.
