Maha Kepakisan, CPA

Building the systems behind better decisions.

From the first click to the balance sheet. CPA turned data engineer. Fifteen years across finance, telco, insurance and transport. Based in Auckland.

Not your average data person

I grew up in Bali, Indonesia, and moved to New Zealand with my family in 2003 when I was 17. We settled in Christchurch, where I spent two years finishing high school before deciding to continue on to the University of Otago in Dunedin. I graduated with a BCom in Accounting and Management in 2009, expecting to spend my career in finance.

But I kept gravitating toward the systems behind the spreadsheets. I started tinkering. Built my first macro. Wrote my first SQL query. Couldn't stop. The accountant slowly became a data engineer, and I think that crossover is genuinely my biggest edge. I understand what the numbers mean to the business, not just how to move them.

Over 15 years I've worked across financial services, telco, insurance, SaaS, big-four consulting at PwC, and now transport infrastructure. I've built data platforms from scratch, migrated legacy systems to cloud, earned 28 certifications, and led engineering teams, all while staying a hands-on builder myself. Currently I operate as sole digital developer and 2IC to the Director of IT at Ritchies Transport, owning the full technology and data function end to end: from Power BI analytics and low-code automation through to full stack Azure serverless applications.

I've completed a Postgraduate Diploma in Information Governance (Distinction) at the University of Auckland because I believe governance is what separates sustainable platforms from expensive tech debt. I'm always up for a good conversation about data, whether that's a problem you're stuck on, a project that needs another pair of hands, or something bigger. My door's open.

This site is my honest record of that journey. Pull up a chair.

Selected work

Four projects from three organisations, plus one for a friend. In red: what each one meant for the business.

Ritchies Transport, for the Ministry of Education 2024 - now

Competitive edgeBuilt in-house for the Ministry contract. No competitor has it, it saves buying a tool, and it strengthens this and future tenders.

RADAR

A full stack school bus routing and contract management system for the Ministry of Education's SESTA contracts, managing sensitive student profiles, medical requirements and real-time scheduling.

Ritchies Transport 2024 - now

$60ka year in Fabric capacity avoided

OpsCentre

A real-time fleet safety dashboard. Live IoT events from the buses stream through Azure Functions and Web PubSub into a React static web app, instead of paying for Power BI Fabric capacity to do the same job.

PwC New Zealand 2019 - 2023

New revenueA brand new revenue stream for PwC, with a client's first report designed to be about two hours from onboarding.

Xero account reconciliation

A client with hundreds of branches had hundreds of separate Xero accounts, merged by hand at head office. I built a pipeline from the Xero API into PwC's global data platform with one consolidated Power BI view, and close to hands-free onboarding.

Pro bono 2026

Meridian Clinical Strategy

A mate needed a website for his business, fast. Instead of building it for him, I set him up the way I run my own site: Claude Code, GitHub, Azure Static Web Apps and a custom domain. Now he asks Claude for a change, it pushes to GitHub, and the site updates itself.
