About me
I am a Full-Stack Software Engineer and Software Architect with a degree in Computer Engineering and 6+ years of experience. I build applications end-to-end, from analysis to production, with Java/Spring Boot, Angular/TypeScript, PostgreSQL, Docker and REST APIs. I have delivered custom management systems, public-administration platforms, mobile apps and third-party integrations (payments, open banking/PSD2, AI assistants). I can start from scratch or take over an existing codebase. Clear milestones, documented code, post-delivery support. Message me and I'll tell you if I'm a fit.... Read more

SicDev_Studio

Founder & Full Stack Developer

SicDev Studio • Freelance

Jun 2026 - Present • 2 mos

I run my own software studio, delivering custom web applications, management systems and mobile apps end-to-end — analysis, architecture, development, deployment and maintenance. My main project is QuantoSpendo, a personal finance app I designed, built and launched on my own: Spring Boot backend, Angular web app, native iOS and Android clients, cross-platform subscriptions and full observability, live on the App Store and Google Play with a growing base of paying users. Alongside it I deliver client work across public administration, e-commerce and nonprofit projects, including secure authentication with Keycloak, Stripe payments, PSD2 open banking integrations and AI assistants built on RAG pipelines.

Maggioli

Senior Software Developer & Software Architect

Maggioli • Full-time

Jan 2026 - Present • 7 mos

Design and development of software solutions for Italian public administrations, working on systems used daily by municipalities and public bodies. Backend in Java/Spring Boot, frontend in Angular, on architectures that have to meet public-sector requirements for security, accessibility and data protection. I work across the full lifecycle — analysis, architecture, development and release — on long-lived systems where maintainability matters more than speed of delivery.

SmartChain

Full Stack developer

SmartChain • Full-time

Oct 2021 - Dec 2025 • 4 yrs 2 mos

Full-stack development of custom web applications, from requirements analysis to production release. Backend in Java/Spring Boot with REST APIs and relational databases, frontend in Angular. Worked both on direct client projects — including a tax and accounting firm — and on long-term consulting assignments with two companies: eighteen months on banking software for Reactive (Almaviva Group), and eighteen months on public administration projects for IFM. Both required working inside the client's team and standards, on systems with strict security and compliance requirements.
