Work

A mobile product for practising spoken language across 100+ languages. Speech is recognised on-device, so a learner can practise without a network, and AI-driven feedback fills in the coaching a phrasebook cannot.

• Offline speech-to-text with Vosk, falling back to the Android recogniser when it helps
• Conversational AI responses served through AWS Lambda, kept optional so the core loop works unplugged
• Translations cached to disk; state held in StateFlow and rendered by Compose

• Kotlin
• Jetpack Compose
• MVVM
• Coroutines / Flow
• Vosk
• AWS Lambda

A clinical records product for managing patients and the pile of images, scans and PDFs that come with them — built to work entirely on-device, where clinic connectivity cannot be assumed.

• Side-by-side medical image comparison with independent rotation, zoom and save-back at full resolution
• Attachments across images, PDFs, video and documents, handed off to the right external app
• Soft-delete recycle bin, multi-field search and an active-patients-first sort that matches how wards actually work

• Kotlin
• Room
• MVVM
• Coroutines / Flow
