Engineering

Custom products built for the ten-thousandth user

Product engineering is where the boring decisions matter: authentication, permissions, data modelling, and what happens when a customer has fifty thousand records instead of the twenty in your demo.

  • Auth, roles, and multi-tenancy from the start

  • Developed against realistic data volumes

  • Incremental delivery you can review weekly

The foundations we insist on

Authentication and roles, early

Retrofitting permissions into an app that assumed one user type is one of the most expensive rewrites there is. We do it first.

A data model that matches the domain

Most performance problems we are asked to fix are schema problems wearing a caching costume. Get the model right and the queries get easy.

Realistic seed data

We develop against production-like volumes, because pagination and query-performance bugs do not show up with twelve rows.

What we build

  • Multi-tenant platforms and customer portals

  • Internal tools and admin dashboards

  • Self-serve billing and subscription flows

  • Data-heavy reporting interfaces

  • Third-party API integrations and webhooks

  • Background jobs, queues, and scheduled work

  • Mobile apps where a product needs one

Where timelines actually slip

Not the features. The integrations. Third-party APIs with poor documentation, sandbox environments that behave differently from production, and OAuth flows with undocumented edge cases.

We build buffer for these and flag which ones worry us in the first week, so a two-day surprise does not become a two-week one nobody warned you about.

AI features, when they earn their place

Building an AI demo takes a weekend. Building an AI feature that behaves acceptably for thousands of users at a defensible cost is engineering — retrieval quality, an evaluation harness, cost and latency budgets, and defined behaviour for when the model times out or refuses.

Prompts are maybe a fifth of that work. If a feature is better served by a database query than a model call, we will say so.

  • Evaluation harness first, so prompt changes are measured rather than guessed

  • Model routing by task — small models where the task is narrow

  • A defined failure state for every AI surface, not a spinner forever
