Android
Kotlin · Jetpack Compose · Material 3
Android is the widest-reaching platform on earth and also the most fragmented. We build for the real device landscape — from flagship phones to budget devices on slow networks — with architecture that keeps large apps maintainable as they grow.
What we build
- Consumer and enterprise apps, from utilities to full trading terminals
- Offline-first experiences that sync reliably
- Custom rendering: charts, drawing tools, real-time feeds
- Background work, notifications, deep links and app shortcuts
- In-app update and direct-APK distribution when Play is not available
How we engineer it
- Kotlin with Coroutines/Flow, Compose UI, MVVM/MVI with clear layers
- Room, DataStore and WorkManager for durable local state
- Baseline profiles and startup optimisation, R8 shrinking
- Play App Signing, staged rollouts, Play Integrity where required
- Instrumented tests on a device matrix including low-end hardware
iOS
Swift · SwiftUI · UIKit
iOS users expect precision. We build to Apple's Human Interface Guidelines and design for App Review from the first sprint, so submissions pass cleanly and the app feels native in every gesture.
What we build
- SwiftUI-first apps with UIKit where it earns its place
- Widgets, Live Activities, Siri shortcuts and share extensions
- Secure flows: Face ID / Touch ID, Keychain, App Attest
- Real-time dashboards, media and chart-heavy interfaces
- StoreKit subscriptions and in-app purchases where applicable
How we engineer it
- Swift concurrency (async/await), Combine, structured state
- Core Data / SwiftData, background refresh, push (APNs)
- TestFlight beta rings, phased releases, review-ready metadata
- Privacy manifests, data-use declarations, ATT compliance
- XCTest / UI tests, Instruments-driven performance tuning
Windows
WinUI 3 · .NET · Flutter desktop
Desktop software still runs the world's workstations. We deliver Windows applications that feel like first-class citizens: fast startup, multi-window workflows, keyboard-first interaction and painless installation.
What we build
- Trading terminals and data-dense professional tools
- Line-of-business apps with local databases and printing
- Cross-platform desktop products sharing code with macOS/Linux
- System-tray utilities, background agents, hardware integration
- Self-updating installers for direct or enterprise distribution
How we engineer it
- WinUI 3 / WPF with MVVM, or Flutter desktop for shared code
- MSIX and classic installers, Authenticode code signing
- Auto-update channels with delta downloads and rollback
- GPU-accelerated rendering for charts and large lists
- CI builds on Windows runners with signed release artefacts
macOS & Linux
SwiftUI · AppKit · Flutter · .NET
Whether your users are on MacBooks or Linux workstations, we ship native-feeling desktop apps with proper packaging, signing and update flows — not wrapped web pages.
What we build
- macOS apps: notarised, sandboxed where required, Mac App Store or direct
- Linux apps packaged as AppImage, .deb/.rpm, Snap or Flatpak
- Menu-bar and background utilities, CLI companions
- Shared desktop codebases across Windows, macOS and Linux
- Ports of existing Windows tools to Mac and Linux
How we engineer it
- Platform-specific UX: menus, shortcuts, window management
- Hardened runtime, notarisation and Gatekeeper compliance
- Sparkle-style update feeds or built-in updaters
- Reproducible builds per distribution target
- Automated packaging in CI for every release
Web & PWA
React · Next.js · Flutter Web
A web application has to be fast, discoverable and accessible on every screen. We build modern front-ends and installable PWAs that stay maintainable as they grow.
What we build
- Customer portals, dashboards and admin panels
- Installable PWAs with offline support and push
- Marketing and product sites with strong Core Web Vitals
- Real-time interfaces driven by WebSockets
- Design systems shared with the mobile apps
How we engineer it
- TypeScript everywhere, component-driven architecture
- Server-side rendering / static generation where SEO matters
- Accessibility to WCAG 2.2, keyboard and screen-reader tested
- Performance budgets enforced in CI (Lighthouse)
- CDN delivery, edge caching, secure headers and CSP
Cross-platform with Flutter
One codebase · six targets
Flutter is our default for products that must exist on phones, desktops and the web at the same time. Done well, it delivers native-grade performance and a single, consistent product — with per-platform polish where users notice.
What we build
- Apps shipping to Android, iOS, Windows, macOS, Linux and Web from one repo
- Custom-painted UIs: charts, canvases, editors, real-time visualisations
- Native integrations through platform channels when a feature needs it
- Localised, RTL-ready interfaces with multi-script typography
- Shared design systems that still respect each platform's conventions
How we engineer it
- Clean layering: presentation, domain, data; state management that scales
- Golden and widget tests, integration tests on real devices
- Per-platform builds, signing and store uploads automated in CI
- Performance profiling: jank, memory, startup, battery
- Native fallbacks when a platform demands it — no dogma
Backend, APIs & Infrastructure
Node.js · PostgreSQL · Redis · WebSockets
Apps are only as good as the services behind them. We design APIs and data systems that are secure, observable and ready for growth — and we run them in production, not just on a laptop.
What we build
- REST and WebSocket APIs with versioned contracts
- Event-driven workers, schedulers and real-time fan-out
- Payment, KYC, messaging and third-party gateway integrations
- Admin back-offices and reporting pipelines
- Multi-region or edge delivery for high-latency or restricted networks
How we engineer it
- PostgreSQL with migrations, transactional money paths, idempotency keys
- Authentication, authorisation, rate limiting and audit logging
- Secrets management, TLS everywhere, least-privilege infrastructure
- Structured logging, metrics, alerting and health checks
- Zero-downtime deploys, backups, disaster-recovery runbooks
Fintech & Real-time Trading Systems
