Your mobile app. From concept to the stores.

I build mobile applications with modern technology, native performance and a backend built to scale. iOS, Android or both platforms.

30 minutes free, no commitment

iOS and Android from a single codebase

I use React Native and Flutter to build apps that work on both platforms without doubling the effort. Native performance, reduced cost.

App + backend + infrastructure

Not just the app: I also design and build the backend, APIs and cloud infrastructure. A complete product, not a pretty screen with no engine.

From the store to the user

I manage the full process: development, testing, publishing on the App Store and Google Play, and the first iterations with real user feedback.

How I work

01

Design & prototype

We define the key screens, user flows and MVP features. A navigable prototype to validate before writing code.

02

Iterative development

I build in 1–2 week sprints. A working app from the first iteration, with incremental deliveries you can test on your phone.

03

Launch & evolution

Publishing on the stores, error monitoring and usage metrics. We iterate on real feedback to improve retention and experience.

Who this service is for

  • Startups that need a mobile app as their core product
  • Companies that want to complement their website with a native app
  • Founders with a web MVP who want to expand to mobile
  • Projects that need native features (camera, GPS, push notifications)

Estimated timeline

Mobile MVP in 6–10 weeks. Full app with backend in 3–4 months.

Frequently asked questions

Native or cross-platform app?

Cross-platform (React Native or Flutter) for most projects. Native performance, reduced cost. I only recommend pure native if there are very specific technical requirements.

Does it include publishing on the stores?

Yes. I manage the full process: developer accounts, builds, Apple/Google review and publishing. Plus subsequent updates.

Can I have an app and a web with the same backend?

Yes. I design the backend with APIs that serve both the app and the web. One system, multiple interfaces.

What about push notifications?

I integrate them from the start. Push notifications, deep links and badges to keep your users engaged.

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.
Federico Magnani CTO, glueglue™
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.
Mattia Costa CEO, Gitaigo
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.
Filippo Quercetti CEO, HubWater
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.
Andrea Rinaldo Principal Application Engineer Manager, Emerson
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.
