Solucrew — Software engineering studio

Apps that work offline, connect to your systems, and keep shipping.

We build field operations apps, modernize existing mobile apps and develop new ones — with the web, backend and business systems behind them.

Engineering difference

We understand the hard parts.

The problems that decide whether a product holds together in production — and the ones that are expensive to retrofit later.

  • 01

    Offline-First Applications

    Local-first storage, queued operations and conflict resolution, so the product keeps working where the signal does not.

  • 02

    Complex Workflows

    Processes with real branching, roles and exceptions — modelled properly instead of flattened into a sequence of forms.

  • 03

    Devices in the Field

    Bluetooth printers, barcode and RFID scanners, cameras and signature capture — the parts that work in a demo and break on a real device, in a real depot.

  • 04

    Real-Time Systems

    Streaming data, connection state and reconnection, with interfaces that stay responsive while the data changes underneath them.

  • 05

    Maintainable Architecture

    Boundaries and data models chosen so that the second year of development does not cost more than the first.

Capabilities

One team across the product stack.

Most engagements combine more than one of these. The common thread is software that fits an existing operation rather than replacing how it works.

  • 01

    Field Operations Apps

    Mobile apps for teams working away from a desk — built to keep working offline and to hand clean data back to the systems the business already runs on.

    • Offline-first data and sync
    • ERP and back-office integration
    • Scanning, signatures and printing
  • 02

    Mobile App Modernization

    Keeping existing Android and Flutter apps on current platforms, and shippable through every store cycle, without stopping the product that depends on them.

    • Platform and SDK upgrades, planned ahead of each store cycle
    • Takeover of apps whose developer has left
    • Java-to-Kotlin and native-to-Flutter migration
    • Incremental refactoring
  • 03

    Mobile App Development

    Native-quality mobile products, built to hold up outside ideal conditions — poor connectivity, long sessions, real devices.

    • iOS and Android
    • Offline-first architecture
    • Release and store delivery
  • 04

    Web, Backend & Business Systems

    Web platforms, CRM and business systems, APIs and integrations — delivered with Solucrew's backend and systems engineer.

    • Custom CRM and business systems
    • APIs and third-party integrations
    • Web applications and dashboards

Selected work

A few products we've helped build.

From financial platforms and enterprise applications to field operations and consumer mobile products, we build software designed for real-world use.

Good products start with clear thinking.

From product decisions to technical architecture, we focus on the work that makes software easier to build, scale, and maintain.

How we work

From problem to production.

Four stages. The early ones exist so the later ones do not have to be redone.

  1. 01

    Understand

    The problem, the constraints and the workflow as it actually runs today — before anything is designed around it.

  2. 02

    Shape

    Scope and architecture. The decisions that are expensive to reverse get made deliberately, and early.

  3. 03

    Build

    Incremental delivery, with working software to review rather than progress reported against a plan.

  4. 04

    Improve

    Real usage exposes what the software needs next. Launch is a checkpoint, not the finish line.

Technology

Chosen per problem, not per trend.

The stack follows the constraints of the product. These are the layers the team works across.

  • Mobile

    • Flutter
    • Android
    • Kotlin
    • Java
  • Web

    • React
    • Vue
    • Nuxt
  • Backend

    • Node.js
    • PHP
    • REST APIs
    • WebSockets
  • Cloud & Data

    • Firebase
    • SQL
    • Cloud services

The people behind the work

Built by engineers.

Solucrew brings together mobile engineering, backend systems and product thinking to build software that works beyond the first release.

About Solucrew

Built by engineers, focused on the product.

Solucrew is a software engineering studio focused on building practical digital products and complex business systems.

Our experience spans mobile engineering, real-time platforms, healthcare applications, field operations, backend systems, CRM and custom business software.

We work with businesses that need more than a template — and need engineering decisions that hold up after launch.

From product architecture to implementation, we focus on understanding how the software needs to work in the real world — then building it with the right technologies and a maintainable foundation.

  • Field Workflow Discovery

    $2,000 · 1–2 weeks

    The full $2,000 is credited toward your build contract with Solucrew, on contracts of $8,000 or more.

    We map one field workflow end to end with your team, agree what has to work offline and how it syncs with your existing system, and build a small working version you can hold. Ends with a fixed price for the build.

Projects that follow typically run from $900 for a straightforward update to $45,000+ for a full rollout. The first step tells you which.
