About Alexsander

Alexsander S.Status: Offline
Full-Stack Web & Mobile Developer | React, React Native, Flutter
Sao Jose, Brazil - 7:58 pm local time
Are you looking for one developer who can build your entire product — web app, mobile app, backend, and publish it to the App Store and Play Store? That's exactly what I do.

I'm Alexsander, a full-stack developer with 7 years of experience building complete digital products. I work across the entire stack: from pixel-perfect front-end interfaces in React and Flutter, to robust Node.js backends with Firebase, to getting your app approved and live on both app stores.

WHY CLIENTS CHOOSE ME

Most projects require 2-3 separate specialists — a web developer, a mobile developer, and a backend engineer. I replace that entire team. This means:

- One point of contact instead of three
- Consistent code quality across your entire product
- Faster delivery because there's no handoff friction
- Lower cost with no coordination overhead

WHAT I BUILD

Web Applications
I build modern, responsive web applications using React and TypeScript. Whether it's a SaaS dashboard, an e-commerce platform, or an internal tool, I deliver clean, maintainable code that scales. I've worked with complex state management, real-time features, and third-party API integrations.

Mobile Applications
I develop cross-platform mobile apps using React Native and Flutter that look and feel native on both iOS and Android. From UI design implementation to push notifications, offline support, and in-app purchases — I handle it all. I've published multiple apps to both the App Store and Google Play Store and know exactly what it takes to pass review.

Backend & Infrastructure
I architect and build backend systems using Node.js and Firebase (Firestore, Cloud Functions, Authentication, Cloud Storage, Hosting). I design database schemas, build RESTful APIs, implement authentication flows, and set up real-time data synchronization.

App Store Publishing
Getting your app from "done" to "live" is a skill in itself. I handle the entire publishing process — creating store listings, preparing screenshots, managing certificates and provisioning profiles, configuring builds, submitting for review, and handling any rejections or compliance issues. I've done this dozens of times and know how to get apps approved on the first try.

MY APPROACH

I believe in clear communication and no surprises. Here's how I work:

1. We start with a detailed scope discussion so I fully understand your requirements
2. I break the project into milestones with clear deliverables
3. I provide regular progress updates with demos you can test
4. I deliver clean, documented code with proper error handling
5. I support you through launch and beyond

TECHNICAL SKILLS

Frontend: React, Next.js, TypeScript, JavaScript, HTML/CSS, Tailwind CSS
Mobile: React Native, Flutter, Expo
Backend: Node.js, Express, Firebase (Firestore, Functions, Auth)
Tools: Git, GitHub Actions, REST APIs, App Store Connect, Google Play Console

OPEN SOURCE

I maintain open-source packages used by other developers:
- react-native-flip-card — Animated flip card component for React Native
- react-native-event-emitter — Event system for React Native modules

I'm available 20 hours per week and am based in Brazil (GMT-3). I'm fluent in English and Portuguese.
