Senior backend & frontend developer

Building resilientsystems.

Independent software development for ecommerce platforms, web applications and the systems behind them — from backend services and API integrations to frontend development, cloud infrastructure and production support.

Bridging new development and existing systems.

I work across both new builds and established production systems — creating new functionality where it is needed, while understanding and improving the software, integrations and infrastructure already in place.

Building new systems

Connecting the moving parts

Improving existing systems

CAPABILITIES // 01

Four disciplines. One connected engineering approach.

Backend services, ecommerce platforms and frontend interfaces are treated as connected parts of the same production system — not isolated pieces.

Backend engineering

Backend services, APIs, application logic, integrations and data workflows built for reliable production use.

  • Node.js
  • Express
  • Python
  • PHP
  • REST APIs
  • GraphQL
  • Webhooks
  • MySQL
  • PostgreSQL
  • Authentication / HMAC
  • External integrations
  • Data Automation

Ecommerce engineering

Engineering across Shopify, Shopify Plus and Magento / Adobe Commerce — from custom functionality and integrations to platform maintenance and ongoing development.

  • Shopify
  • Shopify Plus
  • Magento / Adobe Commerce
  • App proxies
  • Webhooks
  • APIs
  • B2B
  • Checkout & cart
  • Headless commerce
  • Third-party integrations

Cloud & infrastructure

Cloud infrastructure, deployment and production environments configured and maintained around the applications they support.

  • AWS / EC2
  • Linux
  • Nginx
  • Cloudflare
  • Cloudflare Workers
  • PM2
  • Reverse proxies
  • Deployment
  • Production troubleshooting

Frontend & interfaces

Responsive frontend interfaces designed to work cleanly with the systems, APIs and ecommerce platforms behind them.

  • React
  • TypeScript
  • JavaScript
  • HTML5
  • CSS3
  • Liquid
  • Tailwind CSS
  • Sass / Less
  • jQuery
  • Responsive UI

ENGINEERING_METHOD // 02

Understand first. Change carefully. Build for what comes next.

Good engineering starts with understanding the system, the business requirement and the consequences of change before deciding what should be built.

Understand

Establish how the system works, what matters to the business and where the real constraints are.

Define

Clarify responsibilities, integrations, boundaries and failure points before changing behaviour.

Build

Make focused changes that solve the problem without introducing unnecessary complexity.

Deliver

Ship in controlled increments, observe production behaviour and improve as the system evolves.

Built to work beyond launch.

Whether improving an existing platform or building something new, the goal is software that fits your operations, remains understandable and can evolve as the business changes.

View experience

SELECTED_EXPERIENCE // 03

Experience where it counts. In live systems.

Independent development across established ecommerce operations, custom applications and production infrastructure — from new functionality to maintaining and improving systems businesses already depend on.

[Ecommerce]

Established online retail operations.

Long-term development across Shopify and Magento / Adobe Commerce, including custom functionality, integrations, platform maintenance and technical troubleshooting.

Changes are made with existing operations, customer journeys and business continuity in mind.

[Applications]

Applications connected to real data.

Custom web applications built around external APIs, data processing, automated workflows and customer-facing interfaces.

Backend services, authentication, webhooks and reporting workflows are treated as parts of one connected system.

[Infrastructure]

From implementation to production.

Application deployment and maintenance across AWS, Cloudflare and Linux environments.

That includes deployment configuration, reverse proxies, access controls and the operational details that keep applications running.

WORKING_WITH_ME // 04

One developer. End-to-end accountability.

You work directly with the person understanding the requirements, making the technical decisions, building the solution and supporting what happens after launch.

Direct collaboration

Work directly with the developer responsible for the project, from understanding the requirement through to implementation.

Existing systems first

Understand the current architecture, dependencies and business workflows before introducing changes.

Long-term thinking

Build with maintainability, continuity and future development in mind — not just the immediate task.

Professional discretion

Respect for client confidentiality, commercially sensitive information and the responsibilities involved in live systems.

YOUR_DETAILS

First, how can I reach you?

WHAT_DO_YOU_NEED

Choose relevant service/s.

What can I help with?

ABOUT_THE_PROJECT

Explain it in your own words.

To understand the scope, commitment and whether the project is a good fit.

An approximate range is enough.

An estimate is fine — plans can change.
