Altix Code is a small engineering company that designs, ships and operates production systems — web platforms, iOS and Android apps, and the Postgres and deployment infrastructure they sit on. Everything in our showcase is something we built and still run.
We carry the pager for everything below. It is the most honest portfolio we can offer: the same architecture, the same review standard, the same deployment pipeline we would give you.
The same people design the schema, write the app and own the deploy. Nothing is thrown over a wall, which is why the estimate and the release date tend to agree.
Before any interface exists we agree the data model and the permissions on it. Half of what looks like a design argument turns out to be an unresolved question about who owns a record.
Work lands as small pull requests against a running deployment. You get a URL in week one and it never stops working — there is no integration phase at the end where things go quiet.
A feature is done when a test drives it end to end and someone has exercised it on a real device against real data. A green build alone has never proved an app can open.
Infrastructure as code, documented runbooks, your own accounts. If you want to take the project in-house on day one, nothing about the setup prevents it.
A senior engineer's field guide to React 19.3: useActionState, useOptimistic, the React Compiler, ViewTransition, Fragment refs, and how to review async React code the way a staff engineer would.
A hands-on, command-by-command build of an enterprise Next.js 16 and React 19 application, with every config flag, cache directive, security boundary and TypeScript pattern explained and empirically verified against the real 16.3.6 build — for a senior frontend interview with a week to prepare.
A hands-on, verified tour of what actually happens between your JavaScript and the pixels on screen: the rendering pipeline, live vs static collections, the event loop's real ordering guarantees, layout thrashing, Web Components, and a working virtualized 100,000-row data grid — built and checked in a real browser.
Send the shape of the problem and any constraints you already know — budget, deadline, the stack you are stuck with. You will get a written reply from the engineer who would do the work, not a sales sequence.
