Hire The Architecture, Not Just The Hours

Six ways I work with teams — from a two-week audit that tells you where the system will break, through to leading delivery until your team can carry it without me.

01

Technical Consulting & Architecture Audits

Auditing existing software architectures for bottleneck resolution, scalability plans, and clean code optimization in .NET Core and enterprise Node.js environments.

Typical outcomes

  • Comprehensive microservice architectural reviews
  • Cloud cost containment and container optimization reviews (AWS/Azure)
  • Database index tuning and query bottleneck reports
02

Engineering Leadership & Agile Coaching

Helping engineering teams streamline delivery, design reliable sprints, set up robust CI/CD automations, and establish clean development cultures.

Typical outcomes

  • Defining engineering levels, reviews, and metrics
  • Continuous integration pipeline setup (GitHub Actions, Jenkins)
  • Transitioning to secure, remote-first development pipelines
03

AI Systems & Intelligent Integrations

Designing AI-driven workflows, LLM prompt engineering integrations, vector database setups, and smart search integrations into SaaS and ERP systems.

Typical outcomes

  • Retrieval-Augmented Generation (RAG) system pipelines
  • Automated document classification and OCR pipelines
  • AI agent workflows for data verification and enrichment
04

Cloud & DevOps Modernisation

Moving workloads onto Azure without the bill or the release process getting away from you — containers, pipelines and the guardrails that keep both predictable.

Typical outcomes

  • Containerisation and AKS rollout with environment parity
  • Release pipelines with automated gates and rollback
  • Cost attribution per team, with budgets that alert the right people
05

Full-Stack Product Engineering

Building the product itself — .NET Core services behind React or Angular front ends, delivered by a team that can keep shipping after I step back.

Typical outcomes

  • Production-ready web platforms on .NET Core and React/Angular
  • Data model and API contracts designed for the next two years
  • Handover with documentation the team actually uses
06

System Integration & API Platforms

Getting systems that were never designed to talk to each other into a reliable conversation — REST, messaging, and the retry logic nobody budgets for.

Typical outcomes

  • Integration architecture with explicit failure and retry behaviour
  • Versioned public API contracts and developer documentation
  • Monitoring that shows which integration broke, not just that one did

Start with the problem, then shape the engagement

Most work begins as one of the six above and turns into something slightly different once the real constraint shows up. That is fine — the first conversation is about finding the constraint, not selling a package.

Engineering leadership

Head of Technology, Engineering Manager, or fractional CTO.

Software architecture

Designing or reviewing systems before they become expensive.

Consulting engagements

Fixed-scope audits, modernisation roadmaps, delivery rescue.

Long-term contract

Embedded with your team, remote or hybrid.
