Systems Integration & API Development
Make your systems finally talk to each other
Your tools speak different languages, so a person sits between them retyping. We build the interpreter: the APIs, integrations, and event flows that let your CRM, ERP, and payments talk directly, reliably, and with a record, so nothing gets lost or said twice.

The brief
Every system that doesn't talk is a person copy-pasting
An order placed here, retyped there. A customer updated in one tool but not the other. A report that's only right if someone remembers to sync. Disconnected systems waste hours, and worse, they drift out of sync and quietly corrupt the numbers you trust.
Integration turns your stack into one connected system where data moves on its own. And we build it to be reliable, so it doesn't become a new thing that breaks in the night. The whole point is to remove fragile manual steps without adding fragile automated ones.
A good interpreter loses nothing and says nothing twice.
Anyone can wire two systems together for a demo. Making it survive real traffic, outages, and the same message arriving twice is the actual work: retries, idempotency, error handling, and monitoring, built in from the first commit instead of after the first incident.
What changes
The re-keying just stops
An order placed once, never typed again three tabs over. The hours your team spends shuttling data between systems by hand come back, and the transcription errors that came with them go away.
The numbers finally agree
When systems sync on their own, the CRM, the ERP, and the report stop telling three different stories. There's one source of truth every system agrees on, instead of a quiet drift nobody notices until it's expensive.
Systems react the instant something happens
Real-time events replace the nightly batch, so a payment, an order, or a status change moves through the stack immediately, instead of tomorrow morning when it's already caused a problem.
A stack you can actually change
Clean, documented API contracts mean swapping a tool or adding one is a defined piece of work instead of a game of Jenga. The integrations are yours to understand and extend, never a black box you're afraid to touch.
What we build
The plumbing that connects everything
API development
Secure, documented REST and GraphQL APIs so your systems and partners can talk cleanly: the shared language, written down and versioned.
Third-party integrations
Connections to the payment, CRM, ERP, shipping, and other tools your business runs on, so they're part of one operation instead of islands.
Webhooks & events
Real-time event flows so systems react the instant something happens, instead of on a nightly batch that's already stale by the time it runs.
Data sync
Records kept consistent across systems, with conflict handling so two tools editing the same record don't quietly drift apart.
Middleware & orchestration
A layer that coordinates calls across systems so a complex flow, order to fulfillment to invoice, just works end to end.
Monitoring & alerts
Visibility into every integration, with an alert the moment one needs attention, so a silent failure never gets to surprise you.
The engagement
From silos to one connected system
Weeks 1–2
Map what talks to what
We chart the systems, the data that flows between them, and where it's being moved by hand today. You can't make systems talk until you know what each of them is trying to say.
Weeks 2–3
Design the contracts
Clear API contracts and data models, agreed up front, so every integration is predictable and testable: the shared language written down before anyone builds against it.
Weeks 3+
Build and harden
We build the connections with retries, idempotency, error handling, and monitoring from the first commit, because surviving real traffic and real outages is the actual work.
Ongoing
Watch it in production
We monitor every integration and alert before a silent failure bites, so you hear about a problem from us instead of from a customer, or a report that's quietly been wrong for a week.
How we work
Four rules that keep an integration from becoming a liability
The connections are the easy part. Whether they survive a bad day comes down to these, and we hold them from the first commit instead of after the first outage.
Assume the third party will fail
External services go down, slow down, and change without warning. We build with retries, backoff, and error handling so a blip on their side doesn't lose your data or corrupt your state.
Exactly once, or not at all
Idempotency is the difference between a retry that's safe and a retry that double-charges a customer. We make sure a message that arrives twice is only ever processed once.
Surface errors, never swallow them
An integration that fails silently is worse than one that fails loudly, because you find out from the damage. We build so problems surface and alert instead of hiding until a report is wrong.
Leave it documented and yours
Clean, documented APIs and integrations, never a black box. Your team can understand, monitor, and extend what we build, and we can keep running it if you'd rather stay focused elsewhere.
Built to not break
Six things that separate an integration from a liability
None of these show up in the demo. All of them decide whether the integration is still working, and still correct, three months and one third-party outage later.
Retries and backoff
A momentary blip, a slow response or a dropped connection, is retried on a sensible schedule instead of losing the data. The failure that would have needed a person to notice and re-send handles itself.
Idempotency, exactly once
The same event arriving twice is processed once. This is the whole difference between a safe retry and the double-charge bug that only ever shows up in production, on a Friday, on your biggest customer.
Error handling that surfaces problems instead of swallowing them
Failures become alerts and dead-letter queues you can act on, instead of silent gaps you discover when the numbers are already wrong. The problem is visible while it's still small.
Monitoring and alerts on every link
You can see what's flowing and get told the moment something stops, so an integration's health is a dashboard and a page instead of a customer email asking why their data is wrong.
Rate-limit and quota handling
The integration respects the limits of the services it talks to, queuing and pacing instead of hammering an API until it blocks you. It stays a good citizen so it stays connected.
Documentation the next engineer can read
The contracts, the data models, and the failure modes are written down, so the person who inherits it, your team or ours, isn't reverse-engineering a black box under pressure.
Why it pays
One connected operation instead of a set of islands
Data moves between your tools on its own, so the business runs as one system instead of a relay race of copy-paste between apps that were never introduced.
You can trust the numbers again
When every system syncs from the same truth, the report is right without someone remembering to reconcile it. The quiet drift that corrupts dashboards stops happening.
Problems surface before customers find them
Monitoring and alerts mean a failing integration pages you before it reaches your customer. The window between something breaking and someone knowing shrinks from days to minutes.
It's yours, and you can change it
Documented, clean integrations your team can extend, so the next tool you adopt connects on purpose instead of adding one more thing nobody's willing to touch.

Industry expertise
Wherever the same record lives in more than one system
E-commerce & retail
Storefront, POS, payments, and warehouse kept in sync so stock and orders agree across every channel.
Logistics & distribution
Order, tracking, and inventory systems wired together so a shipment's status is the same everywhere it's read.
Financial services
Payment and ledger integrations where idempotency and an audit trail are the requirement, never nice-to-haves.
Professional services
The CRM, billing, and delivery tools a firm runs on, connected so a client exists once instead of four times.
Healthcare & clinical
System-to-system flows where records have to move reliably and be reconciled instead of retyped between platforms.
Manufacturing
ERP, floor systems, and supplier feeds orchestrated so an order becomes a build becomes an invoice without a human relay.
Tell us the two systems that never agree
That's the first link. Show us where your data is moved by hand today and we'll map what needs to talk to what, and how to make it reliable as well as connected.
Why us for this
We build for the day the API is down
Anyone can wire two systems for a demo. Making it survive real traffic, outages, and edge cases is the job, and retries, idempotency, and monitoring are in from the first commit instead of bolted on after the first incident.
We design the contract before the code
Clear API contracts and data models come first, so integrations are predictable and testable instead of discovered. The shared language is agreed before anyone builds against it.
We hand you something you can own
Documented, clean, monitored integrations, never a black box. Your team can understand and extend them, which is what keeps an integration an asset instead of a liability with a bus factor of one.
Working with Flaidex
01
No lock-in
Standard stack, your repository, your accounts. The integrations are yours to keep and extend; staying with us to run them is a choice, never a dependency the build created.
02
One team, map to monitor
The people who charted your systems are the people who build and watch the connections. No handoff to a delivery team that never saw how your data actually moves.
03
Honest about what to connect
If two systems don't need to talk, we won't wire them just because we can. Fewer, reliable integrations beat a spider's web that no one can reason about.
Questions
What people ask about integration
01Our systems don't talk to each other. Can you fix that?
That's exactly what this is. We build the APIs, integrations, and sync that connect your CRM, ERP, payments, and other tools, so data flows automatically instead of someone retyping it between systems. The result is one connected operation instead of a set of islands.
02What if a third-party service is unreliable?
We assume it will be. We build with retries, backoff, idempotency, and error handling so a temporary outage or a slow response doesn't lose data or corrupt state, and we monitor every integration so you know before it becomes a problem.
03Do you build APIs or just connect to existing ones?
Both. We build secure, documented APIs for your own systems and partners, and we integrate with the third-party APIs you depend on, whichever the job needs. Usually it's a mix of the two.
04How do you keep data in sync?
With real-time events where possible and reliable sync where not, plus conflict handling so two systems editing the same record don't drift apart. The goal is one source of truth that every system agrees on.
05Will we be able to maintain it?
Yes. We build clean, documented APIs and integrations, never a black box, so your team can understand, monitor, and extend them. We can also keep running them for you if you'd rather stay focused elsewhere.
06How do we know an integration is healthy?
We instrument every connection with monitoring and alerts, so you have visibility into what's flowing and get notified the moment something fails, instead of finding out when a customer or a report tells you the data is wrong.
