Your technical co-founder, on demand 🚀
I help startups, founders and digital businesses design, build and scale AI powered products and modern web platforms. From first MVP to production ready systems, I bridge strategy, architecture and hands on engineering.
Working with founders and teams in AI, SaaS, education, marketing and digital services.
Who I work with
I partner with teams that need senior technical leadership without hiring a full time CTO.
You have a strong idea and some traction. You need someone who can turn vision into a realistic technical roadmap and a working product.
You sell strategy, marketing or design and need a reliable technical partner for AI features, integrations and complex builds.
You already ship software but need better architecture, automation and processes to scale without burning your team.
What I do
I combine strategic CTO level guidance with hands on full stack development and AI engineering.
Fractional CTO and technical leadership
- Turn business goals into clear technical priorities and roadmaps
- Define architecture and tech stack for web, APIs and AI systems
- Support build versus buy decisions, vendor selection and budgeting
- Align product, design and engineering around measurable outcomes
AI, GenAI and automation
- Design LLM based systems, chatbots and assistants
- Build document intelligence and knowledge driven agents
- Architect robust and privacy aware data and prompt pipelines
- Identify automation opportunities across operations, support and marketing
Full stack web and marketing sites
- Build modern web apps with React, Next.js and classic full stack stacks
- Create fast, SEO friendly marketing sites and landing pages
- Integrate analytics, CRM, payments and third party platforms
- Implement reusable components and design systems ready for growth
Outcomes you can expect
A realistic roadmap that connects features to business impact, so you stop guessing and start prioritizing.
Systems that scale with your users instead of breaking at every new release.
From idea to shipped features with less overhead, fewer rewrites and clearer ownership.
Selected work and projects

How we work together
A simple collaboration model that fits your stage and budget.
Discovery call
We talk about your product, goals and current technical challenges. You get an honest opinion, not a sales pitch.
Audit and roadmap
I review your architecture, team and processes, then propose a pragmatic roadmap with priorities and quick wins.
Build and improve
I join as your fractional CTO and senior engineer. We ship features, improve systems and establish better practices.
Evolve or handover
As your needs change, I can stay on as a strategic partner or prepare a clean handover to an internal CTO or team.
Engagement options
Flexible ways to work together depending on your stage and needs.
Part time ongoing leadership. Ideal for founders who need regular guidance on strategy, architecture and key technical decisions.
Focused 4 to 6 week engagement to design or ship a specific AI feature, integration or internal tool.
End to end design and development of web apps, marketing sites or platforms using React, Next.js and modern APIs.

I am Giacomo, a fractional CTO and full stack AI engineer. I have a background in digital marketing and performance, and I am the creator of Kerykeion, one of the most used open source astrology libraries in Python. I enjoy turning complex ideas into clear architectures and shipped products.
I work closely with founders, product leaders and small teams who want senior technical ownership without the cost and overhead of a full time executive.
Based in Europe, working remotely with clients worldwide.
Tech I enjoy using
I choose tools that are stable, well supported and appropriate for your stage, not just what is trending.
Kind words from people I worked with
Short feedback from founders, PMs and collaborators.
Giacomo gave us clarity on our technical roadmap and helped us ship our AI features much faster than expected.
