🇺🇸 English Software Engineering student from Lima, Peru, building real products that ship. I integrate AI into software — LLMs, multimodal vision and speech — and work across the whole stack: web, native iOS/Android, Windows/macOS desktop apps and my own Linux HomeLab. My main project is AdaptaPE: an accessibility suite, in production, that lets people with visual or motor difficulties use their browser and PC with voice, colors and body movement. Outside software I work with electronics: ESP32/Arduino prototypes and hands-on diagnosis and repair of PCBs, iPhones, consoles and controllers. |
🇪🇸 Español Estudiante de Ingeniería de Software en Lima, Perú, construyendo productos reales en producción. Integro IA en software — LLMs, visión multimodal y voz — y trabajo en todo el stack: web, apps nativas iOS/Android, escritorio Windows/macOS y mi propio HomeLab Linux. Mi proyecto principal es AdaptaPE: una suite de accesibilidad, en producción, que permite usar el navegador y la PC con voz, colores y movimiento del cuerpo a personas con dificultades visuales o motoras. Fuera del software trabajo con electrónica: prototipos ESP32/Arduino y diagnóstico y reparación de PCBs, iPhones, consolas y mandos. |
Open to / Abierto a: internships · Software and Full-Stack roles · native mobile (iOS/Android) · AI integration · freelance projects · open-source accessibility.
Accessibility suite made in Peru for people with visual, motor or involuntary-movement difficulties. Software Engineering thesis project, shipped as a Chrome Web Store extension and native Windows and macOS apps. I'm the creator and lead developer.
| Feature | What it does | |
|---|---|---|
| 🎙️ | Voice assistant (es-PE) | Wake word "Computadora": scroll, search, click, dictate, zoom, control tabs. Browser or local speech mode. |
| 🎨 | 7 color-blind filters | Protan / deuter / tritan (‑anomaly and ‑anopia) plus achromatopsia, built with SVG color matrices. |
| 🔊 | Contextual reader | Reads buttons and links on hover or Tab with local Spanish voices. |
| 🖱️ | Kinetic Mouse | Moves the pointer with the camera: head/torso, arms/hands/fists or residual limb. Frames are processed locally, never stored or sent. |
| ✋ | Gestures | Point to move, fist to stop, pinch for left/right click, open mouth to click. |
| 🧘 | Motion stabilization | Smoothing and a central dead zone to reduce tremors and small involuntary movements. |
| ⏱️ | Dwell Click | Clicks after holding still on a target for 1 second. |
