¶appXcale is a senior engineering studio for startups and established businesses building mobile products, modernizing the backends behind them, and migrating off the legacy systems holding the business back. We embed with your team1 and ship to production2 — so your company keeps up with its industry instead of falling behind it.
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.
APIs, services, data pipelines, integrations. We build the engine room — Node, Django, Postgres, AWS — that powers your apps, your operations, and the next thing you haven't shipped yet. Reliable, observable, easy to change.
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 operate on — phased, reversible, shipped behind feature flags so the business never stops. AI-ready when you're ready for it.
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 started by helping startups ship faster. We do that same work now for established businesses too — building the mobile apps that put them in customers' pockets, the backends that hold their operations together, and migrating off the legacy systems that quietly tax every other priority. We help companies stay competitive in industries that aren't slowing down.
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.
Be the engineering partner companies call when staying competitive isn't optional — and never want to replace.
Founded in 2022 to connect senior engineers with startups in motion. From Reck'N to Roga, every product we touch ships into real customer hands.
Over the next decade — deeper work in mobile, backend systems, and the modernization of stacks that today's competitive pressure can't wait on. Modern capabilities, including AI, wired in where they actually move the business.
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.
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.
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.
Four 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.
An end-to-end workflow tool that automated cross-border vendor discovery, purchasing, and packing-slip generation for LATAM ↔ China import brokers. Replaced manual back-and-forth with a single integrated platform.
Ongoing mobile product work for a LATAM food-ordering and delivery platform. Embedded engineer, continuous roadmap — and a stack we keep moving toward better personalization and routing as the business scales.
A custom payroll automation system for a LATAM HR firm that also runs our own regional hiring. Replaced spreadsheets and manual processing with a workflow built for recruiters and payroll operations across dozens of teams.
