01/Experience

Professional Experience

Some of the enterprise Salesforce work I've been part of at Xero, across Service Cloud Voice, Data Cloud, performance, and platform modernisation. These were team efforts, and each one is broken down into the situation, the task, the action I contributed, and the result.

Service Cloud Voice · Telephony

Service Cloud Voice Implementation

Situation

Support agents were working across separate telephony and CRM systems, which slowed down response times and made it hard to get a full picture of each customer.

Task

Build and roll out a Service Cloud Voice solution that brought telephony directly into Salesforce.

Action

Working as part of the engineering team, I contributed to implementing Service Cloud Voice and integrating outbound call routing with Salesforce, so agents had call controls, transcripts, and full customer context in a single service console.

Result

Agents became more efficient and customers got a smoother, more personal support experience, with no more switching back and forth between tools.

Data Cloud · Integration

Salesforce Data Cloud Integration

Situation

Customer data was spread across a number of different systems, which made it hard to work from a single, trusted view of the customer.

Task

Integrate Salesforce Data Cloud to bring customer records together and move data reliably at scale.

Action

I worked alongside the team to build and configure the integrations into Salesforce Data Cloud, helping make sure data flowed smoothly, identities were unified, and high volumes of data were processed across the connected systems.

Result

This gave us a consolidated, reliable customer data foundation that supports better insights and the automation built on top of it.

Performance · Apex

API & Apex Trigger Bulkification

Situation

High volume data loads were hitting governor limits and causing slow, unreliable transactions across some of our core processes.

Task

Rework the key APIs and Apex triggers so they could handle enterprise data volumes safely.

Action

I contributed to the bulkification of our APIs and Apex triggers, refactoring the logic to process records in bulk and removing the per record inefficiencies and redundant queries.

Result

This significantly cut down governor limit exceptions, brought transaction times down, and kept performance stable under heavy data loads.

Customer Experience · Service Cloud

Case-Raising Journey Redesign

Situation

Customers raising cases through the self-service help centre were going through a confusing, multi step journey, and their queries were not always routed to the right team.

Task

Redesign the case-raising experience from end to end and make sure every query got to the right team the first time.

Action

I collaborated closely with the team to rework the case-raising journey and the routing behind it, helping simplify the customer facing experience and rebuild the rules that classify and direct incoming queries.

Result

Customers got a clearer, faster way to raise cases, and routing became much more accurate, which cut down on misdirected cases and manual triage for agents.

Data Privacy · Automation

Automated GDPR Compliance

Situation

Meeting our data privacy obligations relied on manual processes that were easy to get wrong and carried real compliance risk.

Task

Enforce GDPR data privacy standards automatically inside Salesforce, without the manual overhead.

Action

I partnered with the team to build and deploy automated GDPR compliance solutions that apply the privacy and retention rules to customer data on their own, without anyone needing to step in.

Result

Customer data privacy standards were enforced consistently, which took away the manual effort and reduced our compliance risk.

Platform Health · Modernisation

Technical Debt Reduction & Modernisation

Situation

Legacy Apex and older automation were pushing up maintenance costs and slowing down how quickly we could ship.

Task

Bring down the technical debt that had built up and move the platform onto current best practices.

Action

I contributed to identifying and working through legacy technical debt, refactoring old Apex and helping migrate outdated workflows over to modern Lightning Web Components and scalable Flows.

Result

The result was a cleaner, more maintainable codebase that is easier to extend and quicker to build on.

04/About

About Me

An enterprise Salesforce engineer focused on building reliable, scalable systems, and the path that shaped how I approach the craft.

I'm a Salesforce Engineer at Xero, where I work with a great team on the platform behind a global customer support operation. I like to engineer things for the long term, with clean Apex, well built Lightning Web Components, and automation that holds up under enterprise data volumes.

I care about writing clean code, solving problems thoughtfully, and building things that genuinely help the people who use them. I also care about performance, data privacy, and keeping technical debt down, so the teams and customers who rely on Salesforce get a fast, dependable experience. Outside of the day to day, I'm always learning, whether that's working towards a new certification or building side projects that push me to grow as an engineer.

2022-Present

Salesforce Engineer at Xero

I started at Xero as a Graduate Salesforce Engineer and have grown into a Salesforce Engineer who helps build and scale the platform behind Xero’s global customer support operation. My work covers a lot of the platform, from contributing to Service Cloud Voice and Data Cloud integrations, to bulkifying APIs and Apex triggers so they hold up under high volume data loads, to helping automate GDPR compliance and modernise legacy code onto Lightning Web Components and scalable Flows. I work closely with my team and stakeholders to turn tricky business problems into reliable, maintainable systems, and I care a lot about performance, data privacy, and the long term health of the platform.

2020-2022

Computer Science at the University of Canterbury

I studied Computer Science at the University of Canterbury, which gave me strong foundations in algorithms, data structures, computer architecture, and software design through projects that ranged from TCP socket programming to game development. Alongside my studies, I gained industry experience through an internship at Sudo-code, and by the end of 2022 I graduated and joined Xero as a graduate Salesforce Engineer.

2018

Where It Started

My journey into software began in high school, where I was amazed by the theories, software principles, and algorithms we studied. I loved the idea that you could build something so complex from scratch, and that curiosity for understanding how systems work and then making them better is still what drives me today.
