Backend, Cloud & Scale
Backend and API infrastructure
built for the load that already broke once
A customer paid and there is no record of it. That is a backend failure with a traceable path: checkout session, payment intent, webhook signature, idempotency key, database write. We follow one real payment through all five and fix what we find — the API, the schema, the queue, the deploys and the alert that should have reached you first. Loopwave ships with 110 passing API integration tests.
A payment failed and nobody knew for a day
Your app crawls at peak hours. Queries that were fine at launch are not fine now, and a payment failure last month went unnoticed for a day. Deploys are manual, and nobody is certain what happens when a server dies. Try this tonight: make one real payment, then find the database row it wrote, the webhook it received and the log line that proves both. If you cannot follow it in ten minutes, the visibility is the problem before the traffic is.
How we work
How we scale it
Profile the real bottlenecks
We put timing around the slow endpoints and read the query plans before touching anything. Usually it is a handful of queries and a missing index rather than the architecture, and that is the cheap outcome.
Design for access patterns
We model and index the database around how it's actually queried, so reads stay fast as data grows.
Automate deploys
We set up pipelines so releases are one command, reversible, and boring instead of risky.
Make it observable
Metrics, logs and alerts pointed at the failures that cost money: a webhook returning 500, a queue that stopped draining, a payment with no matching row.
What you get
Deliverables
- Documented, versioned API
- Optimised and indexed database schema
- Payment integration with reconciliation handling
- CI/CD pipeline with rollback
- Monitoring, logging, and alerting setup
- Runbook for incidents and scaling
Outcome
What changes for you
- Response times stay flat as traffic and data climb.
- Deploys stop being a Friday-afternoon gamble.
- You hear about problems from your dashboard, not your customers.

Questions, answered
Can you fix performance without a full rewrite?
Often yes. Most slowdowns come from a handful of queries and missing indexes, which we can fix in place.
Which cloud do you work with?
Whatever you already pay for. Changing cloud provider is a project of its own and it rarely pays for itself — if a migration genuinely is the fix, we show you the arithmetic before you commit to it.
Do you handle payments and compliance?
Payments, yes: checkout, webhook signature verification, idempotency keys and reconciliation, because the payment failure that hurts is the silent one. Compliance, no: we hold no certification of any kind, we are not a SOC 2 or HIPAA shop, and we will not imply we are. We build to the payment provider's own security requirements and tell you where our line is.
