Mobile Development
Native & cross-platform
Mobile Development
Production-grade Android and cross-platform delivery for teams that need stability, performance, and maintainable architecture.
I work seamlessly with Dublin and GMT timezone teams. Also available in nearby cities: Cork, Galway, Belfast.
Overview
I build and lead mobile products from architecture to release. Whether you need a fractional Android lead, a KMP shared-code strategy, or a full cross-platform rebuild, I ship with the same rigor I apply at Rakuten-scale e-commerce.
What you get
- Fractional Android lead — architecture, code review, and sprint planning
- Native Android (Kotlin) with MVVM, Redux/MVI, Dagger/Hilt, and multi-module structure
- Cross-platform delivery with Flutter or Kotlin Multiplatform
- Production diagnostics — crash/ANR analysis, memory profiling, and device-specific fixes
- CI/CD setup (Bitrise, GitHub Actions) and release pipeline automation
Stack
Methodology
My approach combines deep platform-native expertise with pragmatic cross-platform delivery to maximize both quality and speed. After eight years shipping Android at Rakuten-scale e-commerce and U.S. Bank enterprise environments, I understand exactly where native Kotlin code delivers uncompromising performance — and where Flutter or Kotlin Multiplatform can cut delivery time in half without sacrificing production quality. I begin every engagement with a comprehensive technical audit to surface architectural debt, testing gaps, and CI/CD bottlenecks. From there, I establish module boundaries, dependency injection strategies, and state management patterns that scale with your team. Throughout development, I enforce code review standards, automated testing pipelines, and comprehensive documentation. Every engagement concludes with clean handoff documentation, fully configured CI/CD pipelines on Bitrise or GitHub Actions, and team onboarding sessions that leave your engineers confident maintaining and extending the codebase independently.
Process
Discovery
Stakeholder interviews to align on product vision, followed by a deep codebase audit covering architecture, test coverage, and build times. I then recommend platform selection — native Android, Flutter, or Kotlin Multiplatform — based on your timeline, existing team shape, performance requirements, and long-term maintenance capacity.
Architecture
Design of modular project structure, dependency injection strategy using Dagger or Hilt, state management patterns such as MVVM or MVI, and API contract design with strong typing. All major decisions are documented in an Architecture Decision Record to preserve context for future team members.
Development
Sprint-based delivery with structured PR templates, mandatory code review, and weekly demo sessions. Native modules are used for platform-specific capabilities like camera or Bluetooth, while shared UI and business logic layers eliminate duplication across iOS and Android.
QA & Release
Comprehensive automated testing including unit tests, integration tests, and screenshot testing to prevent visual regressions. CI/CD pipelines on Bitrise or GitHub Actions manage staging builds, staged rollouts, and automated crash monitoring integration for production confidence.
Growth
Post-launch ASO metadata optimization, store asset preparation including screenshots and preview videos, analytics instrumentation with Firebase or Amplitude, and a dedicated support window to stabilize crash rates and user retention metrics.
Deliverables
- Product Requirements Document (PRD) and technical specification
- Architecture Decision Record (ADR) with module diagram
- Production codebase with unit and integration tests
- CI/CD pipeline configuration (Bitrise or GitHub Actions)
- App Store / Google Play metadata and screenshot templates
- Analytics instrumentation (Firebase, Amplitude, or Mixpanel)
- Handoff documentation and team onboarding session
Case studies
Deckbase
Built a production-grade Flutter flashcard app featuring FSRS spaced-repetition scheduling, offline-first Drift/SQLite architecture handling 10,000+ cards locally, and real-time Firebase sync — shipped to App Store and Google Play alongside a Next.js marketing site optimized for organic acquisition.
TaskGate
Delivered a Flutter digital-wellness application with native iOS and Android SDK integrations for partner app gating, scheduled app-blocking logic, and Firebase Cloud Functions backend — achieving sub-1% crash rate and passing enterprise security review.
LoA
Shipped native Android and iOS mindfulness apps with app-intercept layers, customizable affirmation flows, subscription paywalls, and a Next.js web companion — resulting in consistent 4.5+ star ratings and stable DAU growth.

FAQ
What platforms do you develop for?
I specialize in Android (Kotlin/Java), cross-platform Flutter, and Kotlin Multiplatform. This covers native Android apps, iOS-compatible cross-platform delivery, and shared business logic across platforms.
Do you handle both native and cross-platform development?
Yes. I recommend native Android when performance or platform-specific integrations are critical, and Flutter or KMP when timeline and code reuse are the priority. Every recommendation is based on your product requirements, not personal preference.
What does a fractional mobile lead engagement look like?
Typically 2-3 days per week focused on architecture decisions, code review, sprint planning, and unblocking your team. I act as a senior technical voice without the full-time overhead, scaling up during critical milestones.
How do you ensure app quality and performance?
Automated testing (unit, integration, screenshot), CI/CD pipelines, crash/ANR monitoring, and memory profiling. I also enforce code review standards and document architecture decisions so quality persists after handoff.
Can you help with App Store and Google Play submission?
Absolutely. I handle metadata preparation, screenshot templates, build signing, and submission pipelines. I also set up staged rollouts and crash monitoring so the launch is controlled and measurable.
What is your typical project timeline?
A Minimum Viable Product typically takes 8-12 weeks. Fractional engagements are ongoing with monthly renewals. Every project starts with a one-week discovery and technical audit to produce a realistic roadmap.
Do you work with teams in Dublin?
Yes. I collaborate seamlessly with Dublin and GMT timezone teams. Based in Japan, I work flexibly across APAC, EU, and US teams using async-first workflows to minimize timezone friction.
Do you serve nearby cities like Cork, Galway, Belfast?
Yes. I cover Dublin and surrounding areas within the same timezone. Because I work remote-native, physical distance is never a barrier.
What timezone overlap do you offer for GMT teams?
Typical overlap is adjustable within GMT business hours (roughly 9 AM – 3 PM GMT). Weekly check-ins and urgent reviews are scheduled in this window; everything else runs async via Slack or Linear.
Are you familiar with the Europe tech ecosystem?
Yes. I have collaborated on multiple projects with teams across Europe, from startups to enterprises. I can also navigate region-specific compliance requirements and market nuances.
What engagement models are available for Mobile Development in Dublin?
Dublin teams can choose the same flexible models as everyone else: fractional (2-3 days/week), project-based sprints (4-8 weeks), or a monthly advisory retainer. All engagements start with a one-week paid trial.
