Backend and Cloud Services

Backends that scale with you, not drain you before you start.

We build backend systems and cloud infrastructure that are fast, secure, and sized for where you actually are — not where an agency's invoice wants you to be. APIs built right. Cloud costs kept honest. Systems that grow when you grow, on AWS, GCP, or Azure.

  • APIs built clean, documented, and ready to scale
  • Cloud bills sized for your stage, not overbuilt
  • You own all code, accounts, and credentials

PROBLEMS WE SOLVE

We've seen $1,000/month bills for 2,000 users. That's a problem.

The cost and reliability problems we're hired to put behind you.

The problem

Your cloud bill grows every month whether the business grows or not.

How we fix it

We audit the setup, find what's overbuilt or misconfigured, and right-size it so the bill reflects actual usage.

The problem

Infrastructure was built for a scale your product hasn't reached.

How we fix it

We build for the stage you're at now, with the architecture to scale cleanly when you genuinely need to.

The problem

Your current backend struggles under load and wasn't built to grow.

How we fix it

We assess what exists, find the bottlenecks, and restructure what needs changing without rebuilding everything.

The problem

You're handling sensitive data with security bolted on as an afterthought.

How we fix it

Authentication, access controls, and encryption built into the architecture from day one, not added later.

The problem

Slow APIs and queries are losing you users.

How we fix it

Caching strategies, query optimisation, and load balancing so the product stays fast under real-world load.

The problem

You're locked into an agency and can't access your own infrastructure.

How we fix it

We hand over all code, cloud accounts, and credentials. You own it completely and can take it anywhere.

Why Zarle

We build for your stage, not for our invoice.

The working terms that keep your costs honest and your infrastructure yours.

01

Right-sized from day one

We build what you need now, with the architecture to scale when you genuinely need to — not before.

Pay-as-you-go where it fits

For early-stage products, we structure cloud so costs grow only when your usage and revenue do.

We optimise what others overbuild

We assess, restructure, and reduce overbuilt infrastructure — often cutting costs while improving performance.

Security is non-negotiable

Access controls, encryption, and secure API design baked in by default, not sold as an upgrade.

You own everything

All code, all cloud accounts, all credentials — handed over completely. You're never locked in.

Honest platform advice

We recommend the cloud that fits your product and budget, and explain why before any work begins.

Documented and observable

Clean, documented builds with monitoring and alerting so you're never flying blind.

Long-term support

Monitoring, alerting, and a response SLA after launch so issues reach you before users do.

WHAT WE COVER

Everything your product needs to run.

End-to-end backend and cloud, documented so any competent developer can continue building on it.

  1. 01

    Requirements & audit

    We understand your product, your users now, and where it needs to go. For existing systems, we audit before recommending anything.

  2. 02

    Architecture planning

    We map the right architecture for your stage and growth: platform, database, API structure, security, and cost modelling. You see the plan before we build.

  3. 03

    Development & setup

    We build the APIs, database, cloud configuration, authentication, and integrations — clean, documented, and easy to continue building on.

  4. 04

    Testing & security review

    Load testing, security auditing, and edge-case handling. We test under real-world conditions before anything goes live.

  5. 05

    Deployment & monitoring

    We deploy, set up monitoring, and make sure alerting is in place so you know immediately if something needs attention.

  6. 06

    Handover & documentation

    Everything documented. All credentials and access handed to you. You own the infrastructure, the code, and the accounts completely.

CLOUD EXPERTISE

The right cloud platform for your product.

We recommend what actually fits your product and budget — not the one with the biggest margins.

Frequently asked questions

Contact us

Backend and cloud questions, answered plainly. Still unsure? Ask us directly — we usually reply within a business day.

It depends on what you're building: complexity, integrations, expected traffic, and security requirements. Most startups don't need the infrastructure they're sold. We give you an honest scope and a fixed price after understanding your actual requirements, not a quote designed to maximise the project size.

Usually because the infrastructure was set up for a scale the product hasn't reached, resources are running that aren't used, or the architecture wasn't optimised for cost. We audit existing setups and restructure them, moving to right-sized or pay-as-you-go models where appropriate, often reducing costs without affecting performance.

All three are strong cloud platforms; the differences are in specific strengths, pricing, and ecosystem fit. AWS is the most widely used with the broadest feature set. GCP is strong for data and machine learning workloads. Azure fits businesses with Microsoft integrations or enterprise needs. We recommend what's right for your product, and explain why, before any work starts.

Instead of a fixed monthly amount regardless of usage, pay-as-you-go means your costs scale with actual usage. For early-stage products with unpredictable traffic, you only pay for what your product actually uses. As you scale and traffic becomes predictable, the right infrastructure approach evolves.

Yes. We design and build APIs from scratch — RESTful, structured cleanly, documented thoroughly, and built to integrate with whatever your product needs to connect with. Whether it's a standalone API project or part of a larger build, we treat API architecture with the same rigour as any other part of the system.

Security is built into the architecture from day one, not added afterward: secure authentication, role-based access controls, data encryption in transit and at rest, secure API design, and protection against common vulnerabilities. For products handling sensitive data, we discuss compliance requirements and build the appropriate protections in.

Yes — we assess what exists first. We review the code, architecture, infrastructure, and documentation, then give you an honest evaluation of what's there, what's salvageable, and what needs to change before recommending a path forward.

Completely. All code, all cloud accounts, all credentials handed over to you in full. You are never dependent on us to access your own infrastructure. Everything is documented and yours.
