Cloud architecture and backend engineering for enterprise systems
Backend systems and cloud infrastructure designed to stay fast, available and secure as your users, data and transactions grow.
What cloud and system architecture covers
System architecture is the set of decisions that determine how software behaves under real conditions: how data is stored, how services talk to each other, how the system copes with a traffic spike or a failed server, and how it is deployed and monitored.
These decisions are cheap to get right early and expensive to change later. A system that works for fifty users can slow down badly at five thousand if the database was never designed for it, and an outage with no tested recovery plan can stop a business for a day.
OGLAT designs and builds the backend and infrastructure behind enterprise software, either as part of a system we are building or as a standalone engagement to stabilise and scale one you already have. Our core stack is Node.js and Express for APIs, PostgreSQL for data, and AWS or Vercel for hosting.
The Problem
Signs the architecture needs attention
Slow at peak times
Pages and reports crawl at month-end or during busy trading hours, exactly when people need them.
Outages without warning
The team learns something is down from customers, because nothing is monitoring it.
Risky releases
Every deployment is a tense manual exercise, so updates are postponed and pile up.
Rising hosting bills
Cloud spend keeps growing while nobody can say which part of the system is responsible.
What We Build
What we design and build
The scope depends on whether we are starting fresh or improving a running system. These are the areas an engagement usually covers.
API & backend services
Node.js and Express APIs with clear contracts, authentication, rate limiting and versioning.
Data modelling
PostgreSQL schemas designed for your real queries, with indexing, constraints and migrations managed properly.
Cloud infrastructure
Single-region or multi-region environments on AWS or Vercel, defined as code so they can be reproduced, reviewed and rolled back.
Deployment pipelines
Automated testing and deployment, so releases are routine, frequent and reversible.
Monitoring & alerting
Logs, metrics and alerts that tell your team about a problem before users do.
Security & access control
Role-based access, encryption in transit and at rest, secrets management and audit logging.
How We Work
How an architecture engagement runs
- 01
Assess what exists
For a running system we review the code, database, infrastructure and incident history. For a new one we gather the load, data and compliance requirements.
- 02
Design for the real load
We size the architecture to the usage you expect over the next few years, without over-building for a scale you may never reach.
- 03
Build and migrate safely
Changes are rolled out in stages with a rollback path, so the business keeps running throughout.
- 04
Hand over with documentation
Your team receives diagrams, runbooks and monitoring, so they can operate the system with confidence.
Who It's For
Where this fits best
- Companies whose software has slowed down as usage grew
- Enterprises moving from on-premise servers to the cloud
- Teams building a new platform that must scale from day one
- Businesses with an in-house product and no senior backend architect
FAQ
Questions we hear most
Which cloud platforms do you work with?
Mainly AWS and Vercel. We choose based on the workload: Vercel suits web applications that need fast global delivery, and AWS suits systems that need more control over compute, networking and data.
Can you improve a system another team built?
Yes. We start with an assessment of the existing code and infrastructure, then recommend changes in order of impact. Many problems can be fixed without a rewrite.
Do we need multi-region hosting?
Only if you serve users in distant regions or cannot tolerate a regional outage. It adds cost and complexity, so we recommend it when the business case is clear and design a simpler setup when it is not.
How do you keep downtime low during a migration?
We run the old and new environments side by side, move data in stages, test with real traffic patterns and keep a rollback path open until the new system has proved itself.
Why PostgreSQL?
It is a mature, open-source relational database with strong data integrity, good performance on complex queries and no licence fee. It handles the transactional workloads that ERP, CRM and finance systems depend on.
