About Luciano
Product-minded Flutter & Full-Stack Developer helping companies build, modernize, and maintain production-ready mobile apps, .NET backends, TypeScript web workflows, and offline-first systems.
I work mainly with Flutter, Dart, .NET/C#, TypeScript, REST APIs, SQL databases, SQLite, and offline-first mobile flows. I can help you turn requirements into a working Android/iOS app, improve an existing codebase, migrate legacy mobile work such as Xamarin to Flutter, or connect your mobile product with secure backend services and web/admin interfaces.
My delivery workflow uses AI as an engineering accelerator, not as unchecked automation: scoped tasks, versioned guidelines, linting, automated checks, tests where appropriate, and final human validation of architecture, behavior, and code quality. This helps me move faster while keeping technical decisions, responsibility, and quality control in human hands.
Typical projects I can support:
- New Flutter apps from requirements to delivery.
- Maintenance, refactoring, and performance improvements.
- API integration with .NET backends, SQL Server, PostgreSQL, or Supabase.
- TypeScript web/admin workflows with Next.js or Astro when the product needs full-stack support.
- Offline-first workflows with local persistence using SQLite.
- Authentication flows with JWT/refresh tokens and secure backend integration.
- Maintainable mobile architecture using Provider, navigation, services, models, MVVM/Clean Architecture, and SOLID principles.
- Deployment and delivery support with pragmatic engineering practices.
My working style is pragmatic and product-minded: I care about clear scope, readable code, maintainability, testing, user experience, and delivering software that is reliable in production, not just technically functional.
Open to remote freelance projects, short or long-term.

- TragsatecFull-Stack Software Engineer | Flutter, .NET & TypeScript | Mobile, Backend & Delivery OwnershipDIGITAL AND ITNovember 2024 - Today (1 year and 8 months)Valencia, SpainHigh-autonomy full-stack role designing and delivering an internal production application end to end — from requirements and architecture to implementation, deployment, and day-to-day operation — together with a core .NET API consumed by multiple internal teams.On the backend, I built and evolved secure .NET 6/8 REST APIs with JWT and refresh token flows, resource-based authorization, deny-by-default access policies, DTO validation, rate limiting, output caching, health checks, and structured logging with Serilog. I also improved performance on an existing web portal backend, reducing load time from over 6 seconds to under 1 second.On the mobile side, I led the development of a cross-platform Flutter application from scratch, with a strong focus on scalability, maintainability, secure authentication, and offline-first foundations. The app uses Clean Architecture, MVVM, Provider-based state management, GoRouter navigation, SQLite local persistence, JWT/refresh interceptors, code generation, strict linting, localization, and automated testing.I also helped improve delivery consistency through AI-assisted engineering workflows, versioned guidelines, custom lint rules, CI guardrails, and structured review practices.Main stack: Flutter, Dart, Provider, GoRouter, SQLite, C#, ASP.NET Core, EF Core, SQL Server, REST APIs, JWT/Auth, Serilog, Azure DevOps, and GitHub Actions.
