A new site is on its way.
Benjamin MestrezFreelance mobile & web developer
The full site is being crafted right now. In the meantime, here's my CV - and a bit about what I do, below.
About
Got a mobile app to build - or one that's turned slow, buggy, or stuck? That's what I do, as one senior developer you can actually reach - and I build fast, modern websites for businesses that want to be found and convert.
For ~7 years I've shipped native and cross-platform apps people use every day - including one relied on by 1.5M+ users and another serving 7M+ members across six countries.
How I can help:
- Build a new app - iOS, Android & Flutter, from idea to the store.
- Rescue & modernise an app someone else built - stabilise it, then ship again.
- Audit - a fixed-price, honest read on what's solid, what's risky, and what to fix first.
- Websites & landing pages - fast, SEO-friendly sites for SMBs that load instantly and convert.
On the web, I build for speed and search visibility: clean, semantic markup, top Lighthouse / Core Web Vitals scores, mobile-first responsive layouts, and the on-page SEO that helps you rank - page titles and metadata, structured data, sitemaps and accessibility. I can add a light CMS so you can update the site yourself, and you always own the code, hosting and credentials, with no lock-in.
On mobile, two real specialisms: accessibility (apps usable by people with cognitive disabilities) and legacy rescue. Because I'm one person, I de-risk it on purpose - documentation, clean handover, and full ownership of your code.
