About Davide

Hi, my name is Davide!

I help startups, scaleups, and digital teams turn complex ideas into clear, reliable, and scalable web products.

Whether you need to build a new SaaS platform, improve an existing application, launch an MVP, integrate AI features, or make your product more stable and maintainable, I can support you with both hands-on development and technical guidance.

I work mainly with React, TypeScript, Node.js, NestJS, PostgreSQL, Python, Tailwind CSS, REST APIs, and AI/LLM integrations.

My focus is not only on writing clean code, but on understanding your business goals, your users, and the real problem your product needs to solve.

My role is to help you move forward with clarity, pragmatism, and confidence.

What makes me different is the combination of senior engineering experience, product thinking, and an AI-native mindset.

I can work independently, join your existing team, or support founders and product managers who need a reliable technical partner.

I usually help with modern web applications, SaaS platforms, frontend interfaces, backend services, API integrations, dashboards, internal tools, B2B portals, MVPs, refactoring, performance improvements, cloud integrations, and practical AI features such as LLM workflows, automations, and intelligent assistants.

I have worked on products in complex industries such as fintech, healthtech, ESG compliance, B2B SaaS, and digital platforms. This experience helped me develop a practical approach: I care about quality, but I also understand the importance of speed, priorities, and business impact.

Clients usually involve me when they need someone who can quickly understand the context, communicate clearly, make thoughtful technical decisions, and deliver solid software without adding unnecessary complexity.

My goal is to make your product easier to build, easier to maintain, and more valuable for your users.
