Solucrew — Software engineering studio
Software that fits the way your business actually works.
We design and build mobile apps, web platforms, CRM systems and custom software for businesses with complex workflows.
Selected work
Complex products we've helped build.
Four selected examples from the full portfolio, each labelled with the role played and whose work it was.
Solucrew · Consumer Apps
All-in-One Image & PDF Converter
A production Android utility app combining PDF conversion, scanning, OCR, annotation, signing and document tools.
Professional experience · FinTech
Capital Markets Trading Mobile App
A cross-platform trading experience for market monitoring, order workflows, watchlists and portfolio management.
Solucrew · Field Service & Compliance
Field Service & Gas Safety Compliance
An offline-first field-service app for material workflows, maintenance and gas-system safety inspections.
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
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
02
Web Development
Web applications that stay fast and maintainable as the feature set grows, rather than only on the day they launch.
- Product interfaces
- Dashboards and admin tools
- Performance and accessibility
03
CRM & Custom Software
Internal systems shaped around how a business actually operates, instead of forcing the operation to fit off-the-shelf software.
- Custom CRM
- Workflow and process tooling
- Reporting and operations
04
Backend & API Development
Backends designed for the load and latency the product genuinely has, with the data model treated as a first-class decision.
- API design
- Data modelling
- Integrations and services
05
AI & Automation
AI applied where it removes real work — with the evaluation, guardrails and fallbacks that keep it dependable in production.
- LLM integration
- Workflow automation
- Evaluation and guardrails
06
Legacy Modernization
Bringing existing systems forward incrementally, so the business keeps running while the software is replaced underneath it.
- Incremental migration
- Refactoring and hardening
- Platform upgrades
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
Real-Time Systems
Streaming data, connection state and reconnection, with interfaces that stay responsive while the data changes underneath them.
02
Offline-First Applications
Local-first storage, queued operations and conflict resolution, so the product keeps working where the signal does not.
03
Complex Workflows
Processes with real branching, roles and exceptions — modelled properly instead of flattened into a sequence of forms.
04
Maintainable Architecture
Boundaries and data models chosen so that the second year of development does not cost more than the first.
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.
01
Understand
The problem, the constraints and the workflow as it actually runs today — before anything is designed around it.
02
Shape
Scope and architecture. The decisions that are expensive to reverse get made deliberately, and early.
03
Build
Incremental delivery, with working software to review rather than progress reported against a plan.
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.

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.
