Welcome to my portfolio

Full-stack engineer with 20 years of production experience, combining front-end depth, UI/UX leadership in the AAA games industry and strong back-end capability.

I work across product design, architecture, interfaces, APIs, data and cloud services, delivering front end and back end as one coherent system. For the last two years, I have applied that foundation to AI agents and frontier models.

I take hands-on ownership from requirements to production, reducing hand-offs and keeping product experience, architecture and implementation coherent. Based in Hertfordshire, United Kingdom.


The Professional

With 20 years in production engineering, I focus on maintainable architecture, clear requirements, rigorous testing and readable code. Those established practices are what make full-stack agentic delivery reliable rather than fast and fragile.

Engineering Architecture

I design maintainable systems across React, TypeScript, Python and Node.js, with clear separation of concerns, appropriate simplicity, automated testing and performance built into the architecture.

UI/UX & Technical Leadership

I have led UI/UX and engineering teams, including serving as Head of UI in the AAA games industry, mentored engineers and worked across product, business analysis, design and backend disciplines.

End-to-End Contract Delivery

I take hands-on ownership across interfaces, APIs, databases, cloud infrastructure and release, reducing hand-offs while keeping product decisions and implementation coherent.

Communicative

Clear communication with stakeholders and team members is essential to successful delivery.

Enthusiastic

Calm and patient, yet genuinely enthusiastic, I stay motivated and curious throughout every project.

In love with technology

I've been passionate about technology from a young age and explore new engineering and AI capabilities thoughtfully.

Dedicated

I take pride in my work and consistently go the extra mile to deliver considered, high-quality results.

BEYOND DEVELOPMENT

I bring a deep understanding of business dynamics, balancing rapid iteration, shifting priorities, and the strategic goals that drive return on investment. I’m skilled at aligning technical work with business outcomes, maintaining transparent communication with stakeholders, and setting realistic expectations with clients. With hands-on experience in startup environments, I’m comfortable wearing multiple hats and delivering high-quality results swiftly and efficiently.


Technical Expertise

Production experience across UI/UX, frontend, backend and cloud systems, combined with advanced agentic engineering and AI product delivery.

With extensive experience, I focus on timeless architectural principles over fleeting trends. Technology choices are driven by project requirements, not hype.

Frontend

Delivery: Full front-end stack, application architecture, component systems, state and data flows
Experience: Responsive interfaces, accessibility, testing, performance and rich interaction
Technology approach: Product, team and long-term support determine the stack, not a fixed framework preference
Framework experience: React, modern front-end frameworks and the full browser platform

Backend

Delivery: API and service design, data models, integrations and cloud infrastructure
Experience: Security, validation, automated testing, deployment and operations
Technology approach: Product, team and long-term support determine the stack, not a fixed technology preference
Platform experience: Modern back-end frameworks, API platforms, data stores and cloud infrastructure

UI/UX & Product

Product & Interaction:
User journeys, Interaction design, Complex and data-heavy workflows
UI Leadership:
Head of UI experience in AAA games, Cross-functional design delivery
Interface Engineering:
Component systems, Responsive design, Accessibility, Performance
End-to-End Delivery:
Turning ambiguous requirements into coherent production experiences

Agentic Delivery

AI and engineering discipline:
Agentic workflows strictly adhere to Separation of Concerns, Keep It Simple, Don't Repeat Yourself and You Aren't Gonna Need It
Pair-programming techniques:
Multiple frontier models work on the same task, applying pair-programming principles to agentic workflows
Applied AI delivery expertise:
Claude Code, Codex CLI and other AI tools, MCPs, skills, OpenAI and Anthropic APIs and RAG
Output and efficiency:
Structured output, context caching, token savings strategies and prompt-engineering practices

The Result: Speed With Engineering Rigour

Agentic development can increase delivery speed, but the real advantage comes from combining that speed with clear specifications, deterministic safeguards, testing and experienced human judgment. The result is software that remains understandable, maintainable and commercially useful.
