Saltancy designs and builds web, backend, and mobile systems — engineered with the rigour of a crystal lattice, so they hold their shape as you grow.

// What we build

Software built to hold its shape.

Web, backend, and mobile systems engineered like a crystal lattice — every part bonded, load-bearing, and built to set under pressure.

Web Applications

Interfaces with structural integrity. Server-first Next.js, typed end to end, fast under load and built to scale without cracking.

Next.jsRSCTypeScriptEdge

Backend Systems

The load-bearing core. APIs, data models, and cloud infrastructure architected to stay rigid as traffic and complexity grow.

Mobile Apps

One structure, every surface. Cross-platform apps that keep their shape from phone to tablet without a second build.

Process / How we set

We don't type code. We set structure.

Every engagement is a lattice — discrete bonds that lock into something load-bearing, from the data layer up to the surface your users touch.

structure.tsbackend
// map stress points before laying a bond
export function setStructure(b: Brief) {
  const lattice = analyze(b.constraints)

  return load({
    lattice,
    bonds: "typed, tested",
    loadBearing: true,
  })
}

Interface

Built to hold.

A surface rendered from the structure above — same lattice, every screen.

  • 01 · Discover

    Map the stress points.

    We chart constraints, data, and load before laying a single line.

  • 02 · Build

    Lay the bonds.

    Typed, tested, reviewed — structure that locks, not glue that slips.

  • 03 · Ship

    Set under load.

    We deploy into real traffic and watch it hold its shape.

  • 04 · Maintain

    Hold the lattice.

    Monitoring, hardening, and a clean handover so it bears weight for years.

Build with structure
