How TapDigital Elevates Your Engineering

Direct expertise in modern Swift, scalable cloud integrations, Agile leadership, and rigorous quality operations.

Swift & SwiftUI Engineering

Specialising in crafting elegant, lightning-fast native iOS and iPadOS applications utilising modern Swift and declarative SwiftUI. We excel at modular project design, strict thread safety under Swift 6 strict concurrency, lightweight state management, custom animations, and porting legacy codebases smoothly into modern reactive patterns.

  • Swift 6 Strict Concurrency and actor-based data synchronization.
  • Clean architectural MVVM patterns backed by Factory Dependency Injection.
  • Modular Swift Package Manager (SPM) split-target architectures.

Software Systems Architecture

Design resilient, highly scalable architectures that connect native mobile frontends to high-performance cloud backends. Experienced in building event-driven AWS serverless backends (Lambda, DynamoDB, AppSync, SNS/SQS) and on-device logic like CoreBluetooth IoT communication, AR pose-estimation pipelines, and local database syncing.

  • CoreBluetooth integration with custom IoT hardware devices.
  • Event-driven serverless backends utilising AWS Lambda and Rust for high-performance processing.
  • GraphQL schema modeling, AppSync APIs, and robust Firestore synchronization layers.

Agile Coaching & Scrum Master

We don't just write code; we accelerate your team's throughput. Refined through an MBA from Durham University and certified as a Professional Scrum Master (PSM I & II) and Scrum Product Owner (PSPO I), we offer actionable strategies to scale agile delivery, remove engineering bottlenecks, and optimize sprint velocity.

  • Mentoring teams on BDD and Scrum principles to ensure shipping quality code from sprint one.
  • Introducing strict sprint disciplines, continuous delivery integrations, and healthy feedback loops.
  • Strategic alignment between product requirements and modular codebase roadmaps.

Testing Ops & AI Tooling

Unlock modern quality assurance through comprehensive Test-Driven Development (TDD) and Behavior-Driven Development (BDD). We design fully automated CI/CD pipelines to build, test, and distribute products reliably. Additionally, we integrate cutting-edge AI features, including OpenAI/Claude APIs, custom RAG systems, and on-device AI tooling.

  • Writing comprehensive BDD test suites using XCTest and Quick & Nimble.
  • Automating builds, code-signing, and Testflight deployments via Fastlane and Bitrise/GitHub Actions.
  • Deploying custom on-device AI features, zero-knowledge proofs, and local LLM integrations.

Case Study: The Genesis of Peerwalk

At TapDigital, we believe in building tools that fundamentally improve developer velocity. Peerwalk was born to solve the exact inefficiencies we observed in corporate development: end-of-sprint massive pull requests, poor reviewer accountability, and the gap solo developers face with no peer feedback.

We built Peerwalk as an AI-powered iPad and macOS companion app that leverages GPT-4, Claude, and Gemini to guide developers through continuous, over-the-shoulder code reviews. This project stands as a showcase of our capability to construct complex, highly integrated, on-device AI native applications.
