THE CHALLENGE
Your API can't handle traffic spikes without falling over.
THE APPROACH
I design for load — caching, queuing, and horizontal scaling — before it becomes an outage.
SPECIALIST SUPPORT / CONNECTED THINKING
Backend Systems
Reliable systems your product can grow on.
01 / THE BIG PICTURE
Built around
your product.
The backend is where reliability is won or lost. I design APIs, data models, and services meant to survive real traffic and change safely over time — including wiring AI and automation directly into the systems that already run your business.
We start by understanding your existing product, the people using it and the constraints around it. That context shapes the scope—not a preset list of technologies.
Explore the work for product context, or read the process to see how discovery becomes a practical plan.
02 / WHERE THIS HELPS
From friction
to a clearer direction.
THE CHALLENGE
Your data model is a patchwork that's hard to change safely.
THE APPROACH
I re-model and migrate data incrementally, with zero-downtime deployments.
THE CHALLENGE
You need AI or automation in the backend but aren't sure how it fits your architecture.
THE APPROACH
I integrate RAG pipelines, LLM calls, and automation workflows directly into your existing services.

03 / THE SCOPE
What we can
work on together.
These are possible areas of work. We agree which deliverables belong in your engagement, along with priorities, constraints and acceptance criteria.
REST & GraphQL APIs
Well-documented, versioned APIs designed for the clients that will actually consume them.
Database Design (SQL & NoSQL)
Schemas modeled around real query patterns, not just entities on a whiteboard.
Authentication & Authorization
Secure, role-based access control and session management done to established best practices.
AI / LLM & Automation Integration
RAG pipelines, LLM calls, and workflow automation wired directly into existing backend services.
Background Jobs & Queues
Asynchronous processing for anything too slow or too important to run inline on a request.
Need a focused review rather than a full implementation? Include that in your project brief.
04 / TOOLS & TECHNOLOGY
Chosen for the work.
Not the other way around.
The tools below support this service. The final stack depends on your requirements and what already works in your system.

05 / DELIVERY & COLLABORATION
A clear next step.
Then another.
Scope, communication and review points should be understandable from the start. Read the full process or meet the person behind the work.
- 01
Discovery Call
A short conversation to understand the goal, constraints, and what success looks like.
- 02
Scope & Proposal
A clear plan broken into milestones, with timelines and pricing agreed upfront.
- 03
Build in the Open
Regular async check-ins and working software early, not one big reveal at the end.
- 04
Ship & Support
Launch, then a support window to catch anything that surfaces in the wild.
Before implementation begins.
We agree the scope, dependencies, review points and handover expectations. Any support window, ongoing work or additional services should be included explicitly in that agreement.
Start with your briefCan you integrate AI features into our existing backend without a rewrite?+
In most cases yes — RAG pipelines and LLM calls can usually be added as new services alongside what already exists.
SQL or NoSQL — how do you decide?+
It depends on the actual access patterns and consistency needs, not a default preference. I'll walk through the tradeoffs for your specific case.
Do you write tests?+
Yes — critical paths get automated test coverage so changes can be made confidently later, not just at initial build time.
What do you need to get started?+
A description of the problem, your current setup and the outcome you want. Use the project brief to share timing, budget and references. We’ll discuss scope and availability before agreeing an engagement.
