01 — Who I work with

Digital agencies

A senior product engineer who plugs into your team when the stakes are high. I build under your brand, for your client. Agencies like Ingot have leaned on me for years.

“Zeltta are a huge asset for us. Timely, well-crafted apps and dev with good comms.”
Dan WebsterDan Webster · Founder & Director, Ingot

Founders and owner-operators

You bring the idea and the domain knowledge. I do the rest, from the first whiteboard session to the day your customers log in.

“Rikus is trustworthy, dependable, and innovative. Thanks for all your help Rikus”
Thomas NabbsThomas Nabbs · Founder/Director, The Waterboy

02 — Selected work

Every one designed, built and delivered by me.

StarSafe health and safety platform

Star Safety · Web, iOS, Android

StarSafe

Star Safety came to me after a previous vendor failed to deliver. I built the whole platform, and their construction clients now run their health and safety on it daily, from site inductions to job safety analysis forms.

Ōkupu · Marketplace · Web, iOS, Android

The first Māori online translation service

Customers place an order and fluent te reo Māori translators deliver it. I built the payments, automatic payouts, audio recording, and a white-label engine ready for other languages. 1,000+ translations completed.

Tākaro te reo Māori vocabulary game

Game Kings · Language games

Tākaro

The digital companion to Game Kings’ Tākaro te reo Māori games: hundreds of words with native-speaker audio, searchable and organised by game edition.

“Top notch app development!”
Eliot JessepEliot Jessep · Founder, Game Kings
Autism Connect community platform

Autism New Zealand · Community

Autism Connect

A private chat and video platform where people with autism and their families connect with Autism NZ staff and each other: public and private rooms, group and one-to-one video.

Kaivolution food rescue app

Go Eco · Food rescue

Kaivolution

Pickup-and-delivery tracking with impact dashboards. I rode along on the rescue runs first, then built the system around what the crews actually do; the impact reports now back their funding applications.

Nourished for Nil operations system

Nourished for Nil · Repeat client

Two systems, years apart

First an inventory system for their food rescue operation. Years later they came back for a second build to run their food banks and social supermarket. Repeat work is the reference I value most.

03 — How I think

Boring technology ships.

I build on TypeScript, React, React Native, Node and Postgres, because in ten years any good engineer will still be able to maintain it. Your system should never be hostage to one person’s favourite niche tools.

The test is Tuesday morning.

Anything looks good in a walkthrough. The software I’m proud of is the kind people open every working day for years without thinking about it.

One accountable person beats a handoff chain.

The strategist, the designer and the developer are the same person. Whoever took your first call also deploys the code and answers the support email.

04 — How I work

One engineer. The whole job. You own everything.

Step 1

The Scoping Sprint

Every project starts with a short, paid sprint. You leave with a fixed quote and a build plan solid enough to hand to any developer.

Step 2

The build

I do the work myself, from the first call to the final deploy. You see working software within weeks, and every decision is made by the person who has to live with it.

Step 3

Yours from day one

The code, the app, the domain and the data all live in accounts that belong to you. After launch I stay on to manage and improve the system, on retainer or as needed. If you ever want to take it elsewhere, everything is already yours.

Projects typically start at $30k. If your budget or timeline doesn’t fit that, I’ll tell you on the first call and point you somewhere that does.

If I take your project on, it ships.

05 — About

I started Zeltta in New Zealand in 2020 so I could choose my clients and build the unusual, complex systems agencies can’t deliver, where layers of managers and coordination distort the idea and drag the timeline. Working alone, with the whole picture in one head, I can.

Most of the work on this page was built there, for founders and organisations that put the entire build in my hands. These days I run Zeltta from Brisbane, and I keep it small on purpose.

Tell me what you’re building and where it’s stuck. If I’m the right fit, I’ll say so. If I’m not, I’ll point you to someone who is.

Not the right time? and stay in touch.
