Hi, I'm Tom Brierley, a Software Engineer & Developer based in London, UK, with over 10 years' industry experience specialising in AI integrations and custom trained models. I help businesses harness AI to create intelligent, efficient, and user-friendly products.

I build AI-powered applications that combine advanced AI capabilities with clean, scalable code and thoughtful design. I specialise in rapid prototyping, turning business challenges into tangible solutions, and delivering AI systems that are practical, high-impact, and seamlessly integrated into operations.

Services

AI-Assisted Software Development

As a London-based Software Engineer & Developer specialising in AI integrations, I use AI tools strategically to accelerate software development. I focus on automating repetitive tasks, improving workflows, and building robust, maintainable applications.

  • AI-assisted feature development and enhancements
  • Rapid prototyping & MVP builds
  • Codebase modernisation and refactoring
  • Automation of software engineering workflows
  • Performance optimisation for AI-powered applications

AI Discovery & Opportunity Assessment

I help businesses identify high-value AI opportunities. Through stakeholder interviews, workflow mapping, and technical audits, I deliver actionable insights and a roadmap for AI integration.

  • AI opportunity identification and validation
  • Workflow and process mapping for AI implementation
  • Technical landscape review
  • ROI & feasibility assessment for AI projects
  • AI readiness evaluation for businesses

AI-Powered Applications

I design and build AI-powered applications that integrate seamlessly into your existing systems. Using frameworks like LangFlow and LangChain with custom APIs, I create intelligent agents, automated workflows, and domain-specific AI tools.

  • Custom AI assistants and intelligent agents
  • RAG-powered knowledge systems
  • Automated business workflows using AI
  • API integrations with CRMs, CMSs, and internal systems
  • Interactive AI dashboards and analytics interfaces

Custom Model Development

I develop domain-specific AI models using RAG and PEFT to bring your business knowledge into AI solutions. These models provide accurate, context-aware responses while being efficient and cost-effective.

  • Domain-specific AI model tuning (RAG, PEFT)
  • Dataset preparation, cleaning, and curation
  • Model evaluation and benchmarking for accuracy
  • Guidance on AI governance, security, and compliance

UX & UI Design for AI Applications

I create user experiences for AI applications that are intuitive, accessible, and enjoyable. By combining research, prototyping, and design iteration, I ensure AI solutions are easy to use and understand.

  • UX research and journey mapping for AI applications
  • Wireframing, user flows, and interactive prototypes
  • Usability testing and recommendations for AI systems

Front-End & UI Development

I build scalable, responsive, and accessible front-end applications that bring AI products to life. Using modern frameworks and design systems, I ensure performance, maintainability, and an excellent user experience.

  • UI development with React and Next.js
  • Design system creation and component libraries
  • Tailwind CSS, SCSS, CSS-in-JS for clean styling
  • Responsive and accessible front-end development
  • Interactive animations and transitions
  • Node.js and modern TypeScript tooling

How I Work

My approach is practical, results-driven, and focused on delivering tangible AI solutions quickly.

  1. Discovery & Alignment Understanding your goals, challenges, and the AI outcomes that will have the greatest impact.

  2. Architecture & Strategy Designing a clear AI and software architecture with technical choices, timelines, and cost planning.

  3. Build & Iterate Rapid prototyping provides tangible results fast. We then iterate based on real feedback to refine AI features and workflows.

  4. Integrate & Deploy Deploy AI systems into your existing infrastructure with reliability, security, and maintainability.

  5. Support & Scale Ongoing AI optimisation, feature expansion, and scaling support to ensure long-term business impact.

Frequently Asked Questions

What AI technologies do you specialise in?

I work with modern, production-ready AI tools including OpenAI GPT models, Anthropic Claude, AWS Bedrock, and the LangChain ecosystem. I also build custom Retrieval-Augmented Generation (RAG) systems, fine-tune models using PEFT, and design intelligent AI agents for automation and internal tools. Much of my work involves vector databases and bespoke API integrations to make AI genuinely useful inside real products.

How long does it take to build an AI-powered application?

Timelines vary depending on complexity, but I always prioritise getting something tangible in your hands as early as possible. Simple AI features can often be delivered within a couple of weeks, while full AI applications usually take around one to two months. More complex systems involving custom models may take longer. Throughout the project, I work iteratively and share regular, working prototypes so progress is clear and you can help shape the direction as we go.

What makes your approach to AI development different?

I combine 10+ years of software engineering experience with a strong background in UX and UI design. That means the solutions I build don't just function well—they're intuitive, robust, and focused on solving real problems. My approach is practical and grounded, centred around rapid iteration, clean architecture, and selecting the right tools for the job rather than chasing trends.

Do you work with businesses outside of London?

Yes. Although I'm based in London, I work with clients across the UK, Europe, and the United States. Most projects are delivered remotely, and I'm flexible with time zones to ensure communication stays smooth and efficient throughout the project.

What does it cost to hire you as a Software Engineer & Developer specialising in AI?

Costs depend on the size and scope of the project. I offer fixed-price options for well-defined work, as well as day-rate arrangements for ongoing development or longer-term engagements. Once I understand your requirements, I'll provide a clear and transparent estimate. My goal is always to deliver the highest value solution within your budget.
