About Me
I'm Roger, an independent mobile app developer based in the Philippines. I've been building software for more than 15 years, with a strong focus on mobile products and connected applications.
I work directly with founders, startups, product teams, and businesses that need someone who can take an idea and turn it into a working product without the overhead of a large agency.
Over the years, I've worked on everything from early-stage MVPs and prototypes to production applications used by real customers. I can join at the beginning of a project, help improve an existing application, or take ownership of a specific mobile feature or product.
My strongest area is native iOS development using Swift, SwiftUI, and UIKit. I also build cross-platform products with React Native, Ionic React, and TypeScript when that makes sense for the project.
I'm particularly interested in products that combine mobile software with real-time systems, Bluetooth Low Energy, location services, live video, cloud platforms, and newer Apple technologies such as Apple Intelligence.
For startups, my goal is simple: build the right version of the product first, keep the architecture practical, and avoid unnecessary complexity until the business actually needs it.

Products I've Built
A few of my own mobile projects, experiments, and independent apps.
Selected Client Work
Mobile applications I've helped build for startups, product teams, businesses, and technology companies.
How I Work
I prefer a straightforward contractor relationship: understand the problem, build the smallest useful version, ship it, then improve it based on real feedback.
- Start with the product. We define what actually needs to be built before adding unnecessary complexity.
- Build lean. For MVPs and startups, I focus on getting a useful product into users' hands quickly.
- Keep it maintainable. The goal isn't just to launch — it is to leave you with a codebase that can continue to evolve.
- Work directly. You communicate with the developer actually building the product.
Tech Stack
Technologies I use across native iOS, cross-platform mobile, backend integrations, connected devices, and real-time products.
Web App Projects
I also build lightweight web products and platforms when a mobile app isn't the only piece of the solution.
- gStandings — sports standings and live scoring platform
- Boracay Jobs — local job platform for Boracay businesses
- EaziPage — no-code tools for creating websites and online stores
