Application Development

Software built to be still working in five years.

Senior teams. Durable software.

Enterprise software is a durability problem. Solvin designs and ships web, mobile and backend systems that stay maintainable at year five — because we invest in architecture, testing and secure SDLC before we invest in features.

/ Capabilities

What's in scope.

Web Application Engineering

React, Next.js, TanStack — with SSR/edge rendering, design systems and accessibility (WCAG 2.2 AA) built-in.

Mobile Application Engineering

Native iOS (Swift/SwiftUI), Android (Kotlin/Jetpack Compose), and cross-platform (React Native, Flutter) when it fits.

APIs & Micro-services

REST, GraphQL and event-driven architectures on Kafka/Kinesis with contract testing and versioning strategy.

Legacy Modernisation

Strangler-fig refactoring, mainframe/COBOL to Java/.NET, monolith-to-service decomposition with domain-driven boundaries.

Product Design & UX Engineering

Research-led design systems, prototyping and design-to-code pipelines that respect brand and accessibility.

Secure SDLC & Quality Engineering

SAST, SCA, DAST, IaC scanning, threat modelling per release, and automated test pyramids with CI-blocking gates.

How we deliver

Small senior pods, discovery-first, and short iterations. Discovery outputs a working prototype and a scoped roadmap — not slideware. Delivery ships to production behind feature flags from week one.

Discovery sprint (2 weeks) → clickable prototype + architectural spike
Delivery in 2-week iterations with demo, retro and reprioritisation
Production from day one behind flags; no year-long integration branches
Handover with runbooks, on-call rotation and 30/60/90-day support

What good architecture looks like

Bounded contexts, versioned contracts, observability from day one, and a test suite you can trust. We treat these as non-negotiable — because everything else compounds against them.

Common questions.

Do you work fixed-price or T&M?

Both. We use fixed-price for well-scoped discoveries and MVPs, and time-and-materials for long-running platform engagements. We publish the trade-offs before the SoW.

Will you use our internal engineers?

Yes. Blended pods are our default — knowledge transfers naturally, and your team owns the code the day we leave.
