01 — SELECTED WORK

Built, shipped, running in production.

Every capability below is backed by software we designed and built end to end, then took all the way through to release. A selection is shown here, with links where the work is public.

Cogent AI

LIVE ON THE APP STORE ANDROID AWAITING RELEASE

iOS & Android · concept to public release

An iOS app that helps people pause before an impulsive decision: capture the urge by voice or text, get the bias behind it named, sit out a cooling-off timer, then talk it through with an AI coach. Taken from a blank repo through App Store review to a public listing.

  • Whole lifecycle: data model and backend API through to store listing, review and release management.
  • Paid from day one: subscription tiers, in-app purchases and a free trial wired in and working.
  • AI in production: a real-time voice coaching session over WebSockets, plus AI analysis of what the user writes.
iOS & Android Subscriptions AI features App Store release

Nestling Nutrition

LIVE IN PRODUCTION

Marketing site + web app · nutrition consultancy

A marketing site and a separate subscriber app for a New Zealand nutrition consultancy. Parents track a child's growth and allergen introductions, generate recipes, plan the week's meals, and export a report for their paediatrician.

  • Recipes and meal planning: allergen-aware recipe generation feeding a weekly planner, which rolls up into a single aggregated grocery list.
  • Records worth keeping: growth percentiles, allergen introductions and reactions, exported as a paediatrician-ready PDF.
  • Two systems, one brand: an SEO-first marketing site and a subscription app, deployed separately so either can change without touching the other.

Sports Academy Platform

IN PRIVATE TEST

Management platform · community sport

Everything a grassroots sports academy runs on, in one system instead of five spreadsheets: player records, attendance, fixtures and match stats, academy finances and a season calendar.

  • One record per player: profile, guardians, medical, academic and consent history held against a single identity.
  • Run the season: attendance registers, fixtures, per-player match stats and a shared calendar.
  • Money tracked properly: income and expenses per player and per academy, summarised on a dashboard.

  • Taking over a site or app someone else left half-built

03 — WHY CODENEST

The advantage of going direct.

You Talk to the Engineer

The person who scopes your project is the person who builds it, from the first conversation through to handover. Nothing gets lost being relayed through an account manager, and you never have to explain your business twice.

Fast Where It Counts

Slow, clunky software loses customers before they see what you offer. Everything we build is tested on a real phone on a real connection, not just a developer's laptop. This site scores full marks on Google's own page-quality tests — your build is held to the same standard.

Scope and Price, in Writing

You get the scope, the price and the timeline in writing before any work starts. And if an off-the-shelf tool genuinely serves you better, we'll say so before you spend a dollar — we'd rather earn a client for years than an invoice for a month.

You Own Everything

Source code, infrastructure and documentation are yours from day one. Systems are built to be handed over, not to lock you in — any competent engineer could pick up where we leave off.

Tell Us What You Need Built.

An engineer — not a salesperson — reads every enquiry and replies within one working day. No pitch deck and no discovery fee: just a straight answer on whether we can help and what it would take.
