Solutions Architect for cloud and enterprise integration

Sixteen years designing and building production systems for teams in the US, Europe and the Middle East.

I turn business requirements into architecture that survives real load, real failure and real delivery teams - and I still build it myself.

Expertise

What I do

Requirements into architecture

Turning what the business actually needs into a design a delivery team can build, with the trade-offs written down.

discovery · non-functional requirements · design documentation · decision records

Integration architecture

Making separate systems agree, and keep agreeing when one of them misbehaves.

canonical data models · system-of-record ownership · contracts & versioning

Scale, load and cost

Sizing a system for the load it will actually see, and for what it will cost to run at that load.

capacity planning · throughput & latency budgets · cost modelling

Reliability and failure design

Deciding what the system does when something upstream breaks, and making that visible to the people who run it.

idempotency · retry & replay · graceful degradation · reconciliation

AI adoption, governed

Getting AI into production without creating a governance problem: what the model may see, who signs off before output reaches a customer, and what it costs to run at volume.

data boundaries · human review gates · validated output · auditability · cost control

Security and governance

Least privilege, data classification and auditability, taken through formal review rather than bolted on after.

access control · data residency · audit trails · compliance review

On platforms: AWS, Azure and Google Cloud, and an AWS Certified Solutions Architect. But the platform is a procurement decision. The architecture is the part that has to be right: the shape of the design, the failure modes, and what it costs to run in three years.

Selected work

Two systems I can show end to end

Thirty-plus production platforms across sixteen years. Most live inside client estates I cannot publish, so these are two I own outright - where I can walk through the architecture and the reasoning behind it, rather than just name the outcome.

AI assessment platform · live with paying users

Three paid AI products on one platform. Payments run as an event-driven pipeline with idempotent handling, so a duplicate message cannot double-charge or double-issue. Every AI response is validated against a schema before a customer can see it.

  • serverless
  • event-driven payments
  • validated AI output
  • scales on demand

Multi-tenant AI receptionist · runs unattended

Answers the call, books the slot, runs the follow-up. Voice, chat and email share one knowledge base and one follow-up engine, so an opt-out on any channel stops them all.

  • multi-tenant
  • event-driven
  • usage-based billing
  • unattended operation

The rest - enterprise integration, ERP and platform work for clients across the US, Europe and the Middle East - sits under client confidentiality. Happy to walk through any of it on a call.

How I think

Every architecture decision is a trade-off

There is rarely a best option, only the one that fits the constraint you actually have. My job is to choose it deliberately, write down why, and leave enough of a trail that the next person can revisit the decision when the constraint changes. A worked example:

The problem
A platform had to read records in milliseconds, under a write volume nobody could predict from one month to the next.
The decision
A simple key-value database, rather than the traditional relational one everyone expected.
What it cost
The reporting team lost the flexible queries they were used to running.
How we covered it
A nightly export into a reporting database gave those queries back, a day behind instead of live. Nobody needed them live.
The result
Reads stayed fast at any load, and the client never paid for capacity sitting idle.
