About me
Tech Lead at Finanz, a fintech app for financial education featured on Forbes and Repubblica: from 40,000 to 500,000 users, and from one release every 30-60 days to one a week. I build Flutter apps for iOS, Android and web, backends on Supabase and Node.js, AI features on the Anthropic and OpenAI APIs, and n8n automations with LLMs. I work test-first: specs and tests before code, with an agent-first workflow on Claude Code that I published as open source (doe-kit, lexi). You get code that is tested, documented and ready for production. I speak Italian and English.... Read more

Finanz

Tech Lead & Software Engineer

Finanz • Freelance

Apr 2025 - Present • 1 yr 7 mos

I lead development at Finanz, a financial education app that grew from 40,000 to over 500,000 users, available in more than 25 languages and ISO 27001 certified. Process and team • Introduced a layered delivery process: daily async Looms, two-week sprints, daily stand-ups, then one-week sprints. From one release every 30-60 days to one a week, with the same team: a fix now reaches users in 7 days instead of 60. • Story points, sprint metrics and team KPIs, tracked on a custom-built internal dashboard (React, Supabase, Notion API). • Technical hiring, with a first automated screening of candidates' repositories run by an n8n workflow with an AI agent. Product and code • Consumer app in Flutter for iOS and Android, plus a white-label Flutter Web platform (Melos monorepo) in production with partner banks and financial institutions. Over 2,200 personal commits across the two repositories. • Built a test suite from scratch on a codebase that had none: 800+ unit tests, from the API layer up to domain providers. • Product features including the News section and Finanz AI. Automated prompt optimization for Finny, the assistant that generates smart tips: a generate-evaluate-iterate loop on the Anthropic API, from 8.62 to 8.94/10 across 17 variants. • Internationalization treated as architecture, with server-side translations, supporting the launch in the Spanish market. AI engineering • Agent-first workflow: I write specs and tests, Claude Code executes, and a hook prevents any task from being marked done without green tests. Specialized agents for code review and agentic QA on the iOS simulator with Marionette MCP. The method became an open-source project, doe-kit.
