Who this is for

Built for agencies that need more AI delivery capability

This is for agencies that are already working closely with clients and are seeing growing demand for agentic engagements. The opportunity is not just in building features, but in delivering systems that create real impact across products, workflows, and business operations.

Many agencies have the relationships and commercial access to open these conversations. What they often lack is enough specialist capability to confidently scope, design, and deliver these systems in production. That’s where I come in—as an embedded partner across scoping, design, and delivery.

Have a client opportunity in mind?

Where this works best

Client Proximity

You work directly with clients and are involved in shaping solutions—close enough to identify real opportunities.

Commercial Expansion

You are or want to move into delivering high-value agentic systems for your clients—beyond surface-level features.

Delivery Gap

You need specialist capability to scope, design, and deliver agentic systems for production.

Embedded Partnership

You want a partner who can operate alongside your team in client-facing engagements.

What I do

Production-grade agentic systems for your clients

I design and deliver agentic systems that operate across real workflows by leveraging domain knowledge and integrating data, tools, compliance, guardrails, and decision logic into structured execution.

These systems are built to perform reliably in production, with a focus on measurable outcomes, system integrity, and long-term maintainability.

Agentic systems are non-deterministic, so they require planning, evaluation, and ongoing control in order to perform reliably in production.

Agentic Systems Engineer

System Design & Architecture

Agentic systems are designed as structured systems, not isolated model calls—combining orchestration, data, and decision logic into coherent workflows.

Multi-agent architectures with defined roles and responsibilities

Workflow-driven execution across real business processes

Integration with APIs, databases, and internal systems

Domain-Aware Reasoning Systems
Evaluation, Observability & Tracing
Production-Grade Delivery
Structured Delivery (ADLC)

Technical capability

Lead full-stack engineer building production-grade agentic systems

I bring 14+ years of full-stack and cloud engineering experience across startups, agencies, and scale-ups—designing and delivering systems that operate reliably in production.

This includes building event-driven architectures, serverless platforms, and domain-driven systems on AWS, alongside modern web and mobile applications.

Backend & Cloud Architecture

Frontend & Product Delivery

I design and build agentic systems that operate across real workflows—combining models, tools, data, and decision logic into structured execution that performs reliably in production.

Multi-agent & orchestration systems

I build multi-agent systems and orchestration workflows that coordinate reasoning, tool usage, and execution across APIs, databases, and internal services, enabling complex tasks to be handled end-to-end.

Evaluation, observability & control

I implement evaluation pipelines, tracing, and validation layers to measure system behaviour, track outputs across workflows, and ensure performance remains consistent as systems evolve.

Data & context systems

I design and implement RAG pipelines, tools, and context systems that ground agent behaviour in real data, enabling accurate, domain-aware reasoning across tasks.

How delivery works

A structured approach to delivering agentic systems

Delivery is structured through the Agentic Delivery Lifecycle (ADLC)—a phased approach designed for non-deterministic systems, where behaviour is continuously evaluated, validated, and controlled.

Each phase builds toward production readiness, with clear outputs and decision points across the lifecycle.

1. Preparation & Hypotheses

Identify where agentic systems can create meaningful impact within existing workflows, define initial hypotheses, and establish early success criteria grounded in real operational context.

2. Scope Framing & Problem Definition

Define the problem, map workflows, establish constraints, and set measurable success criteria, including human–agent responsibilities and data requirements.

3. Agent Definition & Architecture

Design the agent architecture, data flows, evaluation strategy, and cost model—establishing a clear and production-ready system blueprint.

4. Simulation & Proof of Value

Validate system behaviour using real data, measure performance and cost, and establish a clear go / no-go decision based on empirical results.

5. Implementation & Continuous Evaluation

Build the system with integrated evaluation, ensuring behaviour is continuously validated as logic, prompts, and data evolve.

6. Testing

Validate the system across real-world scenarios, ensuring reliability, safety, performance, and readiness for production use.

7. Deployment

Deploy the system in a controlled manner with monitoring, alerting, and safeguards to ensure stable operation in production.

8. Continuous Learning & Governance

Monitor performance, manage system evolution, and maintain alignment as data, models, and usage change over time.

Partnership model

Embedded within your agency, across client engagements

I operate as a fractional partner within your agency—working directly across client engagements to scope, design, and deliver agentic systems.

This enables you to bring senior agentic systems capability into your client work without hiring, building internal teams, or slowing delivery.

Embedded delivery

Work directly within your client engagements—supporting scoping, technical design, and system delivery as part of your team.

How it works in practice

I work across multiple client engagements as needed, focusing on high-leverage areas such as system design, evaluation strategy, and production delivery—while collaborating closely with your team.

To maintain quality and focus, I work with a limited number of agency partners at any given time.

If you have a client opportunity or are looking to expand your agentic system delivery, we can define how this would work within your current engagements.

Pricing and engagement

10 days per month,
on a rolling basis

Large agencies hire Forward Deployed Engineers to work directly within client environments—scoping, designing, and delivering systems.

I provide the same capability on a fractional basis, without the cost or commitment of a full-time hire.

A rolling engagement providing dedicated capacity each month to support active client work and ongoing delivery.

£4,000/month

Engagement Details

10 days per month

Half-day scheduling model

Rolling monthly agreement

Asynchronous communication outside scheduled days

Additional days: £450/day

Working with your existing team

If you already have an internal team building agentic capabilities, I can integrate directly—working alongside your engineers and domain experts across discovery, system design, and delivery.

Longer-term engagements

Longer-term commitments can also be agreed, providing dedicated capacity over an extended period for agencies delivering ongoing client engagements.
