Methodology

How I Build Integrations

API Design & Documentation

OpenAPI 3.0 specs, versioned endpoints, consistent error response formats. Every API I build comes with interactive documentation and example requests.

Authentication & Security

OAuth 2.0 flows, JWT token management, API key rotation, encrypted transport. I implement the auth pattern that fits your security requirements.

Error Handling & Retries

Exponential backoff, dead letter queues, circuit breakers, and alerting. When a third-party service goes down, your integration degrades gracefully instead of failing silently.

Monitoring & Observability

Structured logging, request tracing, health check endpoints, and dashboards. You see exactly what’s happening in your integrations at all times.

What I Deliver

Clear deliverables, no surprises.

REST API Development

Custom API endpoints with authentication, rate limiting, pagination, and versioning. Every API ships with OpenAPI documentation, a Postman collection, and integration test suites.

Third-Party Integrations

I connect your application to CRMs, payment processors, email platforms, shipping services, and custom internal systems. Each integration includes error handling, retry logic, and monitoring.

Data Synchronization

Real-time or scheduled sync between your application and external systems. Conflict resolution, delta sync, and audit logging built in.

Webhook Systems

Event-driven architectures with reliable webhook delivery, signature verification, retry with backoff, and dead letter handling for failed deliveries.

How I Work

How We Work Together

01

Requirements Mapping

We define the integration scope — which systems, what data flows, error handling requirements, and SLAs.

02

Architecture & Design

I design the integration architecture, document API contracts, and identify failure modes before writing code.

03

Build & Test

Incremental builds with integration tests against real sandbox APIs. Every error path tested, load tested, and monitored.

04

Deploy & Monitor

Production deployment with observability from day one — request logging, health checks, alerting, and dashboards.

Simply The Best

“As a professional photographer in my 25 years of having several websites designed across two countries, the UK and Australia. I’ve never encountered somebody like Adrian with his knowledge of all things websites which makes him ’Simply The Best’ ! He’s totally professional with a very personable manner, nothing is too much trouble and he performs every task required with a minimum of fuss and a 100% success. I required a health check and several upgrades on my current website, he completed everything and more. The website has never worked better. It’s even now out performing the website when it was launched and designed by the original website’s web developer. He’s completed tasks that they said couldn’t be done which highlights just how knowledgeable he is when it comes to understanding what makes a website work. I would have no hesitation in recommending Adrian, in fact I rate him at 110%”

Exactly who you want for rush work

“Hired Adrian on a tight deadline and he handled it like a pro. I gave him a punch list and he knocked it out item by item, acknowledging each task and communicating every delivery along the way. That kind of transparency is rare and honestly made the whole process stress-free. He covered everything, WordPress, Elementor, custom code, bug fixes, and the work came out clean and polished. Knows his stuff, doesn't overcomplicate things, and you never have to chase him down for updates. Would 100% work with him again.”

Frequently Asked Questions

Any REST or GraphQL API. Common integrations include CRMs, payment processors, shipping services, email platforms, and custom internal systems.

Yes — I design and build RESTful APIs with authentication, rate limiting, documentation, and proper error handling.

OAuth 2.0, API keys, JWT tokens, and encrypted communication. All integrations follow security best practices.

I build integration layers with versioning and abstraction so API changes don’t break your application.
