What we build

Built around your operations

One integrated platform for the operations you run every day — not another disconnected tool.

Custom Platforms & Portals

Replace spreadsheet chaos with unified tools.

We build the digital backbone of your operations. Whether it's a client-facing portal or an internal line-of-business application, we deliver a unified platform tailored to your specific goals, replacing disjointed legacy tools.

Integration & Data Processing

Stop the manual double-entry.

Your software shouldn't live in a silo. We engineer secure integrations with your ERP, CRM, and payment gateways, and high-volume processing pipelines that move, clean, and transform data reliably.

Universal Access (PWA)

Equip your team, in the field or the office.

We utilize Progressive Web App (PWA) technology to deliver a native-app experience across desktops, tablets, and phones. This ensures your team stays efficient in the field or the office—without the friction and delay of App Stores.

Digital Workflows & Governance

Codify your business logic.

We bake your specific operational rules directly into the software. By managing approvals, routing, and role-based permissions (RBAC), we ensure security and create a clean, audit-ready history for every action.

AI Built In

Automation where it pays off.

We design your software with practical AI and automation from day one: reading documents, cleaning data, and handling repetitive admin, so your team can focus on higher-value work.

Software Rescue & Rebuilds

Rebuilt better, not patched.

Failed projects, unsupported legacy systems, software nobody wants to touch: rather than patching them, we rebuild them better alongside your current system, migrate without stopping the business, and look after them for the long term.

Our stack

Technology expertise

Front-end Architecture

Angular • TypeScript • SASS

Maintainable by Design.

We build strict, type-safe interfaces using Angular and TypeScript to ensure your application remains stable as it grows. We create modular UI systems styled with modern SCSS, delivering a responsive experience that looks great on any screen size.

Back-end Services

C# .NET • Node.js • Python

Logic & Performance.

We select the right tool for the job. We utilize .NET for hardened, complex business rules and Node.js for high-concurrency event handling. Our architectures rely on secure RESTful APIs to ensure fast, reliable data exchange.

Multi-Platform (PWA)

Ionic • Service Workers • Offline Storage

Native Power, Web Delivery.

Get mobile capabilities without the App Store friction. We use Ionic and modern PWA standards to deploy cross-platform applications that leverage device hardware (camera, GPS) and function reliably even in offline environments.

Data Persistence

SQL Server • PostgreSQL • Redis

Integrity First.

Your data is your most valuable asset. We structure it using ACID-compliant relational databases (SQL Server, Postgres) for absolute reliability, while deploying Redis for high-speed caching and instant session management.

Cloud & DevOps

Managed Cloud • CI/CD • Regional Hosting

Secure & Compliant.

We provide fully managed cloud environments protected by automated CI/CD pipelines. We configure hosting in your specific region (EU/UK/US) to ensure low latency and strict compliance with data sovereignty and GDPR.

Ecosystem Integrations

Stripe • Twilio • ERP/CRM • Webhooks

Seamless Connectivity.

We don't use fragile workarounds. We implement deep SDK integrations for payments (Stripe) and communications (Twilio), alongside custom webhook handlers that securely bridge your new software with your existing ERP or CRM.

FAQs

Established, growing businesses with real operational workflows that have outgrown spreadsheets, manual processes, or ageing systems.

We're not the right fit for idea-stage startups looking for an MVP. Our process is built to digitise and scale operations that already exist.

You can, and for prototypes, experiments, and testing an idea it's genuinely great. The hard part of business software isn't getting something that works in a demo. It's making sure it keeps working, for everyone, every day. That's where our expertise comes in:

  • Every case: Edge cases, messy data, permissions, and the unhappy paths real users find on day one.
  • Tested: Automated tests that check every change before it reaches your team or customers.
  • Stable: Monitoring, backups, and safe releases, so it keeps running as your data and usage grow.
  • Secure: Proper authentication, access control, and data protection, built in from the start.
  • Performant: Fast under real-world load, not just on one laptop.

The best of both: vibe code a prototype to explore the idea, then use it as a living spec for us to engineer the real thing properly.

No. To guarantee quality and maintainability, we don't inherit or patch other teams' code. We rebuild it better.

We build the new platform alongside your current one, migrate your data safely without disrupting daily operations, and then stay on to run and evolve it over the long term.

Carefully, and in stages. We map your existing data, clean and transform it, and run test migrations that your team verifies before anything goes live.

We then cut over in planned stages, running old and new side by side where it helps, so nothing is lost and daily operations keep moving.

Yes. We build cross-platform apps with Ionic and progressive web app (PWA) technology. They install on phones, tablets, and desktops, work offline, and can use the device camera and GPS, all from one codebase instead of separate apps for each platform.

Yes. We work closely with your IT team or provider on architecture, security standards, and integrations so the software fits your environment.

To stay fast and accountable, our team owns the build itself. When it's done, we can keep running it for you or hand over with full documentation and code walkthroughs.

We work in short, transparent cycles.

  • Targeted Tools: 4–8 weeks.
  • Full Platforms & Portals: 8–16+ weeks.
  • We agree on milestones upfront and ship increments continuously so you can see progress, not just promises.

Every project is different, so we scope before we quote. You can choose between a Fixed-Scope engagement (for well-defined builds) or Monthly Squad pricing (for evolving requirements).

In both cases, you get a capped budget, clear inclusions and exclusions, and a signed acceptance checklist before final billing.

You do. You own your application, its data, and the IP of the software we build for you.

We keep ownership of our own reusable internal libraries and tooling, and license them to you as part of your system. That way you benefit from years of proven engineering without paying to reinvent it.

Most clients keep us on as their long-term engineering partner. On average, clients work with us for more than three years, across a wide range of their software needs, and some relationships go back to 2017.

  1. 1.Managed Service: We stay responsible for uptime, security patching, and continuous improvement under an SLA.
  2. 2.Handover: If you'd rather run it yourselves, we transition to your team with full documentation and code walkthroughs.

Yes. We regularly sign NDAs and DPAs, complete security questionnaires, and host in your region to meet data residency and GDPR requirements.
