API integrations that carry your business forward.
For agencies and software teams connecting suppliers, booking platforms and business tools. I take one critical data flow from API access to a tested production release.
Integration & Automation Sprint from US$4,000 · commonly 2–4 weeks. Unclear dependencies? Technical Discovery from US$1,500.

João Paulo CavendishSenior software engineer · Founder
I spent five years at Viator, a Tripadvisor company, working on supplier connectivity and marketplace systems at global scale. That experience is directly relevant when integrations carry bookings, availability, payments or other business-critical data.
API integration · DOM Burguer
From restaurant orders to usable operational data.
A GloriaFood API integration, serverless reporting dashboard and customer feedback flow, used for several years at approximately 300 orders per week.
Orders, customers, payments or operational updates are copied between systems because the connection is missing.
02
An existing integration is unreliable
Failures are hard to spot, retries are manual, and nobody is confident that both systems agree.
03
A new vendor must fit your workflow
The vendor has an API, but your team still needs the business rules, edge cases and release work handled properly.
What you get
A working integration, not a handoff document
The exact acceptance criteria are agreed before implementation. A typical sprint takes one defined flow from the current state through production release.
System and data-flow map
Authentication and API implementation
Business rules, validation and error handling
Retries, logs and practical failure visibility
Test scenarios and production release
Technical notes and post-release support window
How it works
A clear path from question to delivery.
01
Map the real flow
We identify the source of truth, required data, business decisions, failure paths and dependencies.
02
Agree on done
You receive a fixed proposal with scope, exclusions, acceptance criteria, schedule and price.
03
Build and release
I implement, test and take the agreed integration through production, then review it with you.
Scope & pricing
Integration & Automation Sprint
From US$4,000
Commonly 2 to 4 weeks
Fixed price for one clearly described integration outcome. The proposal lists what will work, what is excluded, the access you provide and how we will verify delivery.
Third-party access and API limits confirmed before commitment
No 24/7 support or responsibility for a vendor's uptime
The proposal defines the outcome, access, acceptance criteria and delivery boundary.
Before we talk
Practical questions.
Can you work with our existing software?
Yes. Most integration work connects software already in use. I first confirm the code, environments, API access and ownership boundaries.
What if the API is poorly documented?
That uncertainty is assessed before a fixed implementation promise. If it cannot be resolved quickly, I recommend a paid Technical Discovery from US$1,500.
Who does the work?
You work directly with me from scoping through release. If a specialist is genuinely needed, their role and deliverable are disclosed before work starts.
Start a conversation
Which systems need to work together?
Tell me which tools or APIs are involved, what needs to move between them and what is blocking delivery.
I will review your message and reply with questions or a suggested next step. If there is a fit, we can arrange a short call before any proposal.
