How I work

A transparent, iterative process with zero surprises. You see the app come to life every week, from the first sketch to store publication. No middleman, no radio silence, no technical jargon.

1

Discovery call

15 minutes to understand your project, constraints, and goals. No commitment.

2

Scope + quote

I produce a clear scope document with features, timeline, and a fixed price.

3

Design + iterative build

Visual mockups, weekly deliveries. You test on your phone every week.

4

Launch + support

I handle App Store and Google Play submission, then ongoing maintenance afterwards.

Who am I?

Mickael Romaniello — Mobile Product Engineer, Bordeaux

I have been an independent mobile developer for 12 years. I have delivered 15+ iOS and Android apps for startups, SMBs, and established businesses — healthcare, e-commerce, tourism, logistics, education.

I work solo, directly with you. No agency, no middle management, no outsourced juniors. You talk to me, I code, you see results every week.

Frequently asked questions

How much does a mobile app cost?

Budget depends entirely on complexity and scope. A simple MVP starts at a few thousand euros, a full project with backend, payments, and notifications can reach several tens of thousands. I quote a fixed price after a 15-minute call — no surprises afterwards.

How long does a project take?

An MVP can ship in 6 to 10 weeks. A full project typically takes 3 to 6 months depending on features. I ship weekly, so you see progress continuously.

Do you work with clients outside France?

Yes, I work remotely with clients everywhere. Communication in French or English, through your preferred tools (WhatsApp, Slack, or email), GitHub for the code, video calls on Google Meet, WhatsApp, or Telegram as you prefer. Closer timezones are easier, but I adapt.

iOS, Android, or both?

It depends on your audience. For an MVP, we often start with one platform to validate the market. If you need to reach everyone from day one, we can use Flutter to build both in parallel.

Can I get the source code?

Yes, the source code is yours from day one. Hosted on GitHub with full access on your side. No lock-in, no retention: you can transfer the project to another developer at any time.

What happens after publication?

Apple and Google ship major updates every year that sometimes break apps. I offer monthly maintenance contracts to handle OS updates, bug fixes, GDPR changes, and performance monitoring.
