How I can help

You probably don't need more code. You need confidence that the right thing is being built — and a senior pair of eyes on the work before it reaches your customers.

01

Software Engineering & Technical Consulting

“AI made writing code faster. It did not remove the need for engineering judgement.”

I apply independent engineering judgement to your React, Next.js, Node.js and AWS architecture, codebase and development practices — providing the senior technical consulting and hands-on full-stack execution that gives founders, CTOs and engineering teams greater confidence before shipping.

Business outcomes

Increased confidence before shipping

Reduced avoidable production risk

Clearer architecture and maintainability path

Engineering standards that scale with the team

02

Code Review, Codebase Audit & Release Confidence

“Shipping faster shouldn't mean reviewing less.”

An independent codebase audit and engineering health check before your release. I review React, Next.js, TypeScript, Node.js and AWS architecture, testing, performance and maintainability — then give you a clear picture of release risk and what to fix before launch.

Business outcomes

Clear release risk assessment

Surface problems before customers experience them

Improved maintainability and future development confidence

Documented findings your team can act on

03

Technical SEO, Landing Pages & Organic Growth

“I build landing pages designed to capture the searches your customers are already making.”

I combine technical SEO consulting, Next.js website development, website redesign and organic lead generation into one service. I research the exact commercial queries your customers are typing into Google and AI search (ChatGPT, Perplexity, AI Overviews) and build fast, conversion-focused business websites and landing pages designed to turn searches into enquiries.

Business outcomes

Qualified organic traffic from commercial searches

Pages designed to convert, not just rank

Technical implementation that supports long-term visibility

Analytics to measure what drives leads

Product, Custom Web App & MVP Engineering

“Strategy, architecture, implementation and launch — not just code delivery.”

Senior full-stack engineering from idea to production. I combine technical discovery, React / Next.js and AWS serverless architecture, and hands-on implementation to build custom web applications, e-commerce platforms, customer portals, admin dashboards and SaaS MVPs that are maintainable, scalable and ready for real users.

Business outcomes

Production-ready application from day one

Architecture designed for scale, not just MVP

Reduced technical debt by getting the foundation right

Clear technical roadmap for continued development

Code Review & Release Confidence

Shipping faster shouldn't mean reviewing less.

AI tools have made writing code faster. They have not removed the need for engineering judgement. Before your next major release, get an independent senior review of your codebase.

I assess architecture, testing, performance, maintainability and security risk — then give you a clear, actionable picture of release readiness.

Landing Pages & Organic Growth

I build landing pages designed to capture the searches your customers are already making.

Traffic without conversion is not enough. I combine search intent research, Next.js development, technical SEO and conversion optimisation — in one service, without handing implementation to another team.

Most SEO consultants give you recommendations. I also implement them. If your website isn't generating qualified leads from organic search, that is an engineering and strategy problem I can help solve.

About

Engineering, consulting and execution — in one place.

I'm a senior software engineer and technical consultant with 7+ years of experience building and improving production systems across enterprise, fintech, SaaS, government and startup environments.

I combine hands-on engineering with independent technical review — helping businesses ship with greater confidence, improve difficult codebases, and build organic acquisition into their web presence.

Available for remote consulting with global teams. Recognised as an AWS Community Builder.

Why work with me

Advisory and implementation in one

I can both advise on architecture and implement the solution. No handoff between strategy and delivery.

Product, UX and engineering

I understand the full product picture — not only the technical layer. Engineering decisions are made in the context of business outcomes.

Frontend, backend and cloud

Expertise across the full stack means I can review or build the complete system rather than specialising in one narrow layer.

Independent review, not just execution

I can review work critically and independently rather than only building what I am told. This is the difference between a consultant and a contractor.

Technical SEO as an engineering problem

Most SEO consultants hand recommendations to engineering teams. I understand both sides and implement the full solution.

Strategy and hands-on execution

Capable of working at the technical leadership level and then implementing directly. Useful for teams at any size.
