Michel Lutz - Mobile Solutions Architect - Mobile Solutions Architect & Global Pre-Sales

Strategy, Architecture & Innovation.

With over 17 years of experience, I operate at the intersection of Software Engineering and Business Strategy. As a global technical reference within the AI/R Company ecosystem, I lead the architectural definition for Super Apps and critical solutions in Fintech and Retail.

My focus goes beyond code: I drive technical pre-sales, deal structuring, and high-performance team leadership, ensuring that technological innovation generates measurable results.

Tecnologias & Expertise

System Architecture & Strategy

The foundation of scalability. Far beyond UI patterns.

Structural: Clean Architecture, Modularization (SPM/Gradle), Micro-apps Strategy

Scalability: Server-Driven UI (SDUI), BFF (Backend for Frontend) Pattern, Feature Toggles

Design Patterns: Coordinator, Factory, Dependency Injection (DI), and UI patterns (MVVM-C, VIPER) applied pragmatically

Legacy Modernization: Migration strategies (Strangler Fig Pattern), safe refactoring

Architecture Decision Records (ADR): ADR Template (Context, Decision, Consequences), ADR Versioning, Decision Logging, Architectural Knowledge Management

Mobile Architecture Best Practices: SOLID Principles applied to Mobile, Separation of Concerns (Presentation/Business/Data), Platform-Specific vs Cross-Platform Decisions, Performance Budgets, Memory Management Strategies

Engineering Excellence (DevOps)

Quality assurance and delivery speed.

CI/CD Pipelines: Bitrise, GitHub Actions, Fastlane Automation

Observability: Crashlytics, Datadog, Distributed Tracing, Performance Monitoring

Quality Assurance: Unit Testing (XCTest/JUnit), UI Testing (Maestro/Detox), SonarQube

Governance: Code Review Standards, Tech Radar Management, RFCs & ADRs

Architecture Documentation & Knowledge Sharing: C4 Model (Context, Container, Component, Code), Sequence Diagrams, Architecture Decision Records (ADR), Technical Specifications, API Contracts Documentation

Architecture Diagrams & Visual Modeling: C4 Model Implementation, Mermaid Diagrams (Sequence, Flowchart, Class, State, ER), PlantUML, Structurizr, Draw.io / diagrams.net, Reference Architecture Diagrams, System Context Diagrams, Container Diagrams, Component Diagrams, Deployment Diagrams, Data Flow Diagrams (DFD), Event Storming, Domain Modeling

Mobile Ecosystem & Modern UI

Where interaction happens. Deep mastery of native and hybrid paradigms.

Languages: Swift (Advanced), Kotlin, Dart, TypeScript

Declarative UI: SwiftUI & Jetpack Compose (Modern approach), Flutter Widgets

Core Frameworks: Combine, Coroutines, Swift Concurrency, CoreNFC, Biometrics

Cloud, Data & AI Integration

The intelligence behind the interface. Connecting mobile to the world.

Cloud Native: AWS Services (Lambda, API Gateway, Cognito), Azure Integration

Data Resiliency: Offline-First Strategies, Sync Mechanisms, CoreData/Realm/WatermelonDB

AI/ML: GenAI Integration (OpenAI/Bedrock), On-device ML (CoreML), Prompt Engineering for Mobile Context

Security: Token Management (OAuth2/OIDC), Certificate Pinning, Obfuscation & RASP

Current Enterprise Experience

Mobile Solutions Architect & Global Pre-Sales | AI/R Company

Mobile Solutions Architect & Global Pre-Sales

I lead mobile architecture strategy and pre-sales engineering for the global AI/R Company ecosystem, working across group companies (Compass.UOL, Invillia, AvenueCode, Webjump). My focus is ensuring that major commercial opportunities are supported by solid, modern, and scalable technical decisions.

Main Responsibilities:

Architecture & Strategy: Defining stacks for high-complexity projects (Super Apps, Banking, E-commerce), deciding between Native (iOS/Android) or Cross-Platform (Flutter/React Native) approaches.
Technical Pre-Sales (Global): Leading responses to RFPs/RFIs, designing solutions in commercial proposals, and estimating costs/efforts for Enterprise clients.
Modernization & AI: Integrating GenAI into mobile flows and implementing modern patterns such as Server-Driven UI and Clean Architectures.
Technical Governance: Creating internal accelerators and frameworks to standardize code quality and CI/CD pipelines across multiple teams.
Mentoring: Technical development of Tech Leads and Engineers, fostering a culture of innovation and technical excellence.

My Innovation Labs

Where I test new technologies, architectures, UX and get hands-on.

NFC Forge

Create and write professional NFC tags on your iPhone. Support for URLs, social networks, production mode for mass writing and chip password protection.

Complete solution to create and write NFC tags directly on iPhone. Full support for social network links. Production mode for mass writing. Chip password protection (NTAG21x and Ultralight EV1). Tag management with reusable templates. Automatic synchronization via iCloud (CloudKit).

Stack: Swift, SwiftUI, CoreNFC, CloudKit, iCloud

Ver Projeto

RideKeeper

Manage fuel, tires, maintenance and performance of your motorcycle with precision and practicality.

Developed in Swift 6.2 with SwiftUI and SwiftData. MVVM architecture with centralized Data Managers. ModelContainerManager with automatic database recovery. Type-safe localization system with centralized enum (340+ keys). ServiceLocator for thread-safe dependency injection. Firebase Analytics and Crashlytics.

Stack: Swift 6.2, SwiftUI, SwiftData, MVVM, Firebase

Beyond Code & Maker Mindset

I believe that real innovation happens at the intersection of disciplines. My passion for engineering is not limited to software; it overflows into the physical world, where I transform bits into atoms, pilot machines, and capture the world through new lenses. It is in this balance that I find the clarity to solve complex problems.

ML3DPrint

R&D and Prototyping. While Vivaro focuses on the final product, ML3DPrint is my experimental playground. Here, I connect 3D printing with my roots in Robotics and IoT, exploring exotic materials and functional mechanisms. It's the space where I validate concepts, test automations, and push Maker culture to the limit.

The Rider

The Road Strategist. Riding a Harley-Davidson requires the same as good software architecture: planning, peripheral attention, and reaction capacity. The road is my moment of digital disconnection and mental "defragmentation," where I seek new perspectives and recharge energy for corporate challenges.
