Freelancer profile translated to English.

Description

I am a native Android and iOS app developer with 14 years of experience. Throughout my career, I have led and built all types of mobile products—social, maps, e-commerce and subscriptions, encrypted messaging, Bluetooth/IoT, AR, and video games—always with a clear goal: to transform ideas into robust, usable, and sustainable mobile experiences.

In the last two years, I have delved deeper into mobile accessibility. I don't treat it as a checklist, but as a product pillar. I work to ensure apps are inclusive from design to publication, complying with WCAG 2.2 and Apple/Google guidelines, and guaranteeing an optimal experience with VoiceOver/TalkBack, Dynamic Type/Scalable SP, focus and keyboard navigation/Switch Control, AA/AAA contrast, gesture equivalents, accessible forms, and multimedia with captions and descriptions. My goal is to broaden product reach, reduce risks, and improve business metrics without sacrificing performance or design.

Beyond code, I get involved in solution definition: I propose UI/UX improvements, help prioritize, design architecture, and establish metrics for learning and iterating. I like to adopt modern technology when it's production-ready, with CI/CD, analytics, and observability from day one.

Since 2023, I have been coordinating an expanded freelance team (backend, UX/UI, QA, 3D design/animation) through my companies. This allows me to take on projects of various sizes with guarantees: from an agile MVP to a demanding large-scale product, maintaining predictable timelines and delivery quality.

If you're looking for someone who combines technical mastery in native development (Kotlin/Java, Swift/SwiftUI), good scalability practices, and a serious focus on accessibility, I'd be delighted to chat. I can help you turn your idea into a fast, stable, and truly inclusive app—ready to grow and make an impact.

February 2025 - Today (1 year and 6 months)
Dubái, United Arab Emirates
We have rebranded from Appccessibility (formerly MyQodi). Everything we do remains the same and can be seen in the MyQodi experience. We are now also a team specialized in mobile accessibility, integrating it from design to publication.

End-to-End Accessibility Approach
Inclusive design from the start: accessible UI patterns, AA/AAA contrast, minimum touch targets, typographic scalability, and accessible dark mode.
Semantics and screen readers:
iOS: VoiceOver, UIAccessibility, and custom actions.
Android: TalkBack (Views/Compose).
Forms and states: clear labels and hints, announced validations, field-associated errors, and change announcements.
Accessible multimedia: captions, transcripts, audio descriptions, and reader-operable controls.
Graphics/maps: summarized descriptions, access to tabular data, and segment navigation.
Performance and accessibility: resilient layouts for large scales, efficient rendering, and lightweight accessible hierarchies.
Validation, Auditing, and Continuous Quality
Manual testing with VoiceOver/TalkBack, keyboard, and Switch Control.
Tools: Accessibility Inspector (Xcode), Accessibility Scanner (Android).
Compliance audits (WCAG 2.2, Apple HIG, Material Accessibility) with prioritized roadmaps and metrics.
Accessible QA checklists, documented handoffs for design and development, and training for internal teams.
Integration with Your Product and Business
Accessibility aligned with goals: conversions and retention.

January 2025 - Today (1 year and 7 months)
Madrid, Spain
Lead Android Developer for the new version of MyJumpLab, an application focused on physical performance analysis using camera sensors and complex calculations, displaying results through interactive charts.

The project had a nearly unscalable codebase, which required a full refactoring to improve architecture, stability, and performance. Key contributions included:

Progressive migration to Jetpack Compose following Clean Architecture principles
Integration and improvement of error monitoring using Firebase Crashlytics
Implementation of a new local database and migration to Firebase for remote data persistence
Significant improvement in Google Play ratings within a short timeframe
I continue to provide ongoing support and maintenance, keeping the app up to date with Google's latest policies and requirements.
