About Me
Engineered Thinking. Modern Applications.
I build modern web applications and digital products for businesses and startups. Using technologies like Next.js and modern full-stack tooling, I design and develop fast, reliable systems that are built to scale and easy to maintain.
My background is in hands-on engineering and problem solving, where systems had to work safely and reliably in the real world. That experience shaped how I approach software development — structured, practical, and focused on delivering solutions that genuinely work for the businesses using them.
I focus on clarity, performance, and maintainability, building web applications, platforms, and digital tools that clients can rely on long after launch.
01
Full-Stack Development
Modern web application development using Next.js and scalable backend architecture, built for production environments.
02
Component & UI Architecture
Clean, reusable component systems with structured file organisation and long-term maintainability in mind.
03
Performance & Optimisation
Improving load times, bundle size, and application responsiveness through structured engineering decisions.
04
Agency Overflow Partner
Taking responsibility for clearly defined projects and delivering them with minimal oversight and structured communication.
05
Security & Light Pen Testing
I prioritise security in how I design and ship software. I also run light web penetration tests to catch common vulnerabilities before release.
What I Focus On
My Core Systems
I specialise in two distinct types of projects for agencies — full-stack applications and high-performance marketing sites. I also take many of those builds through to production SaaS launches for real customers. Each context needs a different approach, tooling, and priorities.
Full-Stack Projects
End-to-end application development
Structured Engineering
Clean architecture, maintainable code, and production-ready patterns from day one.
Full-Stack Capability
Frontend, backend, database design, authentication, and deployment — handled end-to-end.
Testing & Quality
Proper testing workflows, error handling, and validation built into the development process.
Agency-Ready Delivery
Clear documentation, structured handoff, and minimal oversight required during development.
Content & Marketing Sites
Speed-first, SEO-optimized delivery
Lighthouse Performance
Consistently hitting 95+ scores across performance, accessibility, and SEO metrics.
Fast Load Times
Optimized assets, minimal JavaScript, and edge-ready architecture for instant page loads.
SEO Foundation
Structured data, meta tags, sitemaps, and crawlability built in from the start.
Content-First Workflow
Clean CMS integration, markdown support, and editor-friendly content management.
SaaS & product builds
End-to-end delivery for software people pay to use
Product-shaped engineering
Data models, permissions, and workflows that match how the business actually runs — not a UI bolted onto a spreadsheet.
Auth, access, and trust
Secure sign-in, role-aware views, and server-side validation so customers and staff only see what they should.
Monetisation-ready
Subscription and payment flows wired with clear upgrade paths, webhooks, and reconciliation-friendly patterns.
Built for real traffic
Performance budgets, observability hooks, and deploy pipelines aimed at uptime under genuine daily use.

Reliable, production-tested tooling

Workflow
Who I Am Outside of Code
When I'm not building applications, I'm usually travelling, exploring, or behind a camera — drawn to adventure, open landscapes, and the kind of places that reset how you think. I still love small living environments and mini ecosystems. And when I need to switch off properly, you'll find me on the mats training Muay Thai.
Travel
Adventure on and off the road — discovering new places, cultures, and landscapes, and bringing that perspective back home.
Mini Environments
Terrariums and small ecosystems. So much joy i get in interacting with the natural world.
Photography & Exploration
Documenting places and moments through the lens. Composition, patience, and noticing detail — the same instincts I bring to engineering.
Muay Thai
Discipline, consistency, and showing up. Training keeps me grounded, focused, and sharp away from the screen.
Common Questions
Frequently Asked Questions
I primarily collaborate with agencies and product teams. I do also take on direct client work, helping develop their ideas into a robust application.
I prefer clearly defined outcomes and constraints before development begins. Once scope is agreed and design is provided, I focus on structured delivery, clean architecture, and slotting into existing workflows with minimal disruption.
My core stack centres around Next.js and supabase as a backend. I focus on solid architecture, maintainable codebases, and production-ready builds rather than chasing trends.
Both. I'm available for defined short-term builds as well as longer-term collaboration where structured engineering support is required.
Strong fits include marketing sites for teams that care about performance and long-term maintainability, marketplaces, and SaaS products. I work best when there is a clear brief, existing design direction, or an in-house team to collaborate with.
