Software Development Services

Custom web applications, mobile apps, and automation solutions built for businesses that need reliability, not hype. From single-page tools to enterprise-grade systems, we engineer software that works.

Web Application Development

We build custom web applications that solve specific business problems. Whether you need an internal tool for your team, a customer-facing platform, or a complex data-driven system, we engineer solutions that scale with your business.

Our web applications are built on modern frameworks like Next.js and React, ensuring fast performance, excellent SEO, and maintainability. We focus on creating intuitive interfaces that your users will actually enjoy using, backed by robust architecture that handles real-world demands.

From simple CRUD applications to sophisticated multi-tenant platforms, we've built systems for manufacturing, engineering, construction, and service industries. Every application is tailored to your specific workflows, not forced into a generic template.

Native Mobile Applications

We develop native mobile applications for iOS and Android using React Native and Expo, giving you a truly native experience without the cost of maintaining separate codebases. Your users get the performance, offline capabilities, and device integration they expect from mobile apps.

Mobile applications excel where web apps fall short: offline access, push notifications, camera and sensor integration, background processing, and home screen presence. If your business needs these capabilities, a native mobile app is the right solution.

Whether you're building a consumer app, field service tool, or internal mobile solution, we deliver apps that work reliably in real-world conditions.

What's Included

  • verifiediOS and Android development (single codebase)
  • verifiedNative device feature integration
  • verifiedOffline functionality and data sync
  • verifiedPush notifications
  • verifiedApp Store and Google Play submission

Automation & Integration Solutions

We eliminate manual, repetitive work by building intelligent automation systems. From simple data processing to complex multi-system workflows, we engineer solutions that save time, reduce errors, and scale your operations.

Most businesses lose hours every day to manual data entry, file processing, email management, and system-to-system data transfer. Our automation solutions reclaim that time. We've automated everything from engineering drawing generation to quote-to-invoice workflows, typically reducing 4-hour manual processes to 4-minute automated ones.

The best part? Automation ROI is usually measured in weeks, not years. If you're doing something manually more than once per day, it's probably worth automating.

What's Included

  • verifiedWorkflow analysis and optimisation
  • verifiedCustom automation scripts and tools
  • verifiedThird-party API integrations
  • verifiedData transformation and processing
  • verifiedScheduled tasks and triggers
  • verifiedError handling and notifications
  • verifiedLogging and monitoring
  • verifiedDocumentation and training
  • verifiedOngoing optimization

API Development & Integration

We build robust, scalable APIs that connect your systems, enable integrations, and power your applications. Whether you need a REST API, GraphQL endpoint, or webhooks for real-time data exchange, we engineer APIs that are reliable, secure, and well-documented.

Good APIs are the foundation of modern software architecture. They enable mobile apps to talk to backends, third-party systems to exchange data, and future integrations you haven't imagined yet. We design APIs with versioning, authentication, rate limiting, and comprehensive documentation from day one.

What's Included

  • verifiedRESTful or GraphQL API design
  • verifiedAuthentication and authorization
  • verifiedRate limiting and throttling
  • verifiedComprehensive API documentation
  • verifiedTesting and validation
  • verifiedError handling and logging
  • verifiedVersioning strategy
  • verifiedWebhook implementation
  • verifiedIntegration support
  • verifiedPerformance optimisation

Database Design & Architecture

We design relational databases that scale, perform, and maintain data integrity as your business grows. Good database design is invisible when done right and catastrophic when done wrong. We get it right the first time.

Most performance and scalability problems trace back to poor database design. We design databases following proper normalisation principles, implement appropriate indexes, establish referential integrity with foreign keys, and plan for future schema evolution.

As highlighted in our blog post "Database Design 101", an hour spent on proper design saves weeks of painful refactoring later.

What's Included

  • verifiedEntity relationship modeling
  • verifiedProper normalisation (3NF)
  • verifiedIndex strategy and optimisation
  • verifiedForeign key constraints
  • verifiedMigration planning and execution
  • verifiedQuery optimisation
  • verifiedBackup and recovery strategy
  • verifiedSecurity and access controls
  • verifiedDocumentation (ERD diagrams)
  • verifiedPerformance tuning
