I build web apps, mobile apps and SaaS MVPs for founders and small teams: WeWeb + Xano for low-code web applications, Flutter for Android and iOS from a single codebase, and React or Next.js when a product needs fully custom frontend code. Work usually starts in one of four places: an idea, a Figma design, an app someone else left half-finished, or a product that's live and breaking.
Projects rarely go wrong in the code. They go wrong in the decision made before anyone writes any. So before I quote, I'll tell you whether your product is better built no-code, low-code on WeWeb + Xano, or fully custom, and why I'd pick that for your case rather than the tool you arrived with. Getting that call wrong is what turns a six-week MVP into a six-month rebuild, and that conversation costs you nothing.
What I build
Web apps, SaaS products and internal tools. WeWeb + Xano is my main stack when you need a real database, real REST endpoints and real business logic in production quickly, without committing to a large custom codebase. Dashboards, admin panels, client portals, marketplaces, booking and membership platforms, multi-user apps with authentication, roles and permissions. Full-stack in practice: the database schema, endpoint logic and third-party integrations live in Xano, and the responsive interface on top of them is built in WeWeb, including Figma to WeWeb conversions. Payment, email and CRM services get wired in through their APIs, and Make handles the automations nobody should be doing by hand. Bubble or FlutterFlow when they suit the problem better, React and Next.js when you want full control of the frontend, with Node.js, MongoDB or Firebase behind it. If a spreadsheet and a chain of manual steps are currently running your operation, that's usually the cheapest thing to replace first.
Android and iOS apps in Flutter. One codebase, both stores, instead of paying for two builds. Firebase auth, push notifications, real-time data, REST API integration, and help getting the release ready for the App Store and Play Store. I also take Flutter rescue work: crashes, build failures, dependency conflicts, and the classic case where the app runs fine on Android and falls over on iOS.
Frontends, websites and Figma to code. Figma to React, to HTML, CSS and JavaScript, or to WeWeb, built to match the design instead of approximating it, using Tailwind CSS, Bootstrap or Redux where the project calls for them and tested from small phones up to wide desktop screens. WordPress and Webflow for business sites and conversion-focused landing pages, plus technical and on-page SEO: clean markup, metadata, indexable pages, Core Web Vitals and faster loads, which is the part of ranking a developer can genuinely influence.
Work that's already started. Taking over a stalled build, adding features to a live app, replacing a no-code prototype that has outgrown its platform, connecting APIs that were never finished, or going through an existing codebase and telling you honestly what it would take to fix it. A good share of my work is picking up where another developer stopped, and I'd rather see the code before I quote.
How I work
We start with a short call to agree what version one has to do and, just as usefully, what it doesn't. You get back a scope, a realistic timeline and milestones, then working screens early and often, so the final build is never a surprise. If something is a bad idea, out of budget or solved faster another way, you hear it from me before the money goes in rather than after. Fixed price when the scope is genuinely clear, hourly when it isn't, and I'll tell you which one your project actually is. You finish owning the build, the accounts and the documentation to keep it moving without me.
What you can expect
- Work that holds up on real devices and browsers, not only in a demo
- Architecture chosen for where the product is going, not just for launch day
- Clean builds another developer can pick up without a rewrite
- Bug fixing, debugging and performance work on apps that already exist
- Replies usually within a few hours, in clear English

Send me whatever you have: an idea in a paragraph, a Figma file, a repo, a bug you can't shake, or a launch date you're already behind on. Tell me what the product has to do and when it has to be live, and I'll come back with the fastest realistic route there, or tell you straight if I'm not the right developer for it.
