§ 01 / Practice

Three things
we ship.

A. Mobile
B. Backend
C. Migrations
01mobile

Mobile apps, built to last

iOS, Android, cross-platform. We design, build, and ship the mobile products your business depends on — and own version ten the way we owned version one. Native performance, store-ready, instrumented from day one.

ExpoReact NativeiOSAndroidOTA
02backend

Backends that scale with you

APIs, services, data pipelines, integrations. We build the engine room — Node, NestJS, Django, Postgres, AWS — that powers your apps, your operations, and the next thing you haven't shipped yet. Reliable, observable, easy to change.

NodeNestJSDjangoPostgresAWS
03migrations

Legacy migrations, made surgical

Move off the system that fights every change. We refactor monoliths into services, migrate to cloud-native, and bring stacks up to the standard your competitors already run — phased, reversible, behind feature flags so the business never stops.

§ 01.5 / The model

We embed. We don't disappear.

Our model is dedicated team augmentation — a fixed, named team in your Slack for the long haul, not a rotating bench of subcontractors. Ongoing and indefinite by design, because the best software is built through sustained collaboration.

Every developer is hand-selected through multi-stage interviews with our CEO and tech lead. You get a curated, cohesive team — not random freelancers.

  • One team, one Slack. The people you meet are the people who build it — no subcontracting carousel.
  • Production-grade, not demo-grade. Tests, types, telemetry. Velocity comes from the boring parts.
  • White-glove attention. Boutique by design — every client feels like our only client.
  • Architecture that outlasts the feature. We build the runway, not just the request.
§ 02 / Studio

We are not an agency.
We are a studio that writes code.

appXcale was founded in 2022 on a simple bet — a small, senior, embedded team can move a product further in a quarter than a full vendor can in a year.

We work as an extension of your engineering org. We pair-program, we're in your standups, we open PRs against your repo. We don't hand off Figma comps over the wall and call it a day. The studio is small on purpose — eight people, EST timezone, all senior. The work passes through hands that built it before, and will own it after.

Reck'N
N° 01
§ 03.12024Mobile

Reck'N

We replaced the bar-and-restaurant ordering bottleneck with a custom mobile platform and the backend behind it: a customer app, a venue order-management app, an admin panel, and a web flow that lets even non-app users send drinks. Faster service, less staff load, and a social layer that pulls customers back. The kind of operational backbone hospitality can't buy off the shelf.

§ 03.22024Mobile

DeliDomi

A custom delivery platform that replaced phone-in orders and paper dispatch sheets for Colombian restaurants. Automated order management, optimized route planning, and a customer-comms layer — a clean modernization win for local businesses stuck in pre-app workflows.

§ 03.32023Mobile

Roga

An IoT wearable for stress reduction, paired with a mobile app and on-demand streamed meditation. We delivered the full digital stack around the device — mobile-first, integrated end-to-end, and built for ongoing iteration as the product matures.

Hotels at Home

Sixteen years modernizing the e-commerce platform behind Hilton, Westin, and Ritz-Carlton retail. Multi-brand storefronts, secure checkout, inventory integration, continuous delivery — the kind of long-arc modernization that needs an embedded senior engineer, not a vendor rotation.
