I build SaaS products from the first line of code to the first paying customer.
I do not talk about SaaS in theory. I have built my own, they are in production with real users. I know what works and what does not.
30 minutes free, no commitmentMulti-tenant architecture
I design the foundation from the start to support multiple customers with data isolation, custom configurations and real scalability.
Billing & onboarding
I integrate payment gateways, subscription plans, trial periods and onboarding flows that convert. It is not an add-on — it is part of the product from day one.
Metrics that matter
MRR, churn, activation, retention. I implement tracking from the start so you make decisions based on data, not gut feeling.
How I work
Product definition
We define the business model, pricing plans, user flow and core features together. Before writing code, we know what we are building.
Core development
I build the complete product: authentication, multi-tenancy, billing, dashboard, onboarding. Real infrastructure, not a prototype.
Launch & metrics
Deployment, monitoring, analytics. Your SaaS live with the metrics you need to make growth decisions.

Frequently asked questions
Does it include a payment system?
Yes. I integrate Stripe or other gateways with subscription plans, trial periods, invoices and failed payment handling.
What is multi-tenancy and why does it matter?
It is the architecture that allows multiple customers to use the same software with their data isolated. Essential for any SaaS that wants to scale.
Can you build on top of my existing product?
Yes. I evaluate your current architecture and add what is missing: billing, multi-tenancy, analytics or whatever you need.
How do I know which metrics I need?
I implement the standard SaaS metrics from day one: MRR, churn, activation, retention. We then adjust based on your business model.

Vedrai I worked with Francesco as backend lead on one of the most technically demanding projects I've been involved in. The stack spanned several very different technologies, and he took ownership of all of them, getting up to speed remarkably fast. What impressed me most was his ability to integrate complex systems on first contact — grasping how unfamiliar pieces fit together and making them work correctly, the first time. That instinct is rare, and it made him the person the team relied on when the hard problems landed (we still rely on him as of now!). I'd gladly work with Francesco again and recommend him to any team that needs a dev who can own complexity rather than be slowed by it.
Francesco is a professional who conveys confidence, not only from the point of view of in-depth technical skills but above all thanks to his way of tackling the most complex challenges. I feel confident, in conclusion, in suggesting Francesco as a real added value for any development team.
Francesco is an incredible hardcore worker, efficient and super skilled. He helped my organisation throughout all the development of a industry changer IoT system which required a massive effort on the backend side.
Francesco is an excellent programmer, whose great skills have allowed him to handle a variety of areas with excellent results, especially on the back-end and web development side. He is well suited to teamwork and knows how to respect agreed schedules, even under heavy stress and tight deadlines.
I strongly recommend Mr. Francesco Antonio Sessa as Back-End Web Developer. During 2016, I had the pleasure to collaborate with Mr. Sessa in the context of various Web Development projects for KCS Media Srls. I was impressed by his capability of capturing and leveraging my personal feedback to the extent of evaluating and reviewing the ongoing services. I also appreciated his capability of smoothly entering and boosting multiSite development, and his very helpful and flexible attitude towards the team. He has many soft skills, a very sharp analytic approach to problem solving, and a natural inclination to exploring new opportunities. Overall, I strongly recommend Mr. Sessa as a skilled as well as trusted professional in Web development and Web maintenance matters.
