Rahul Pahuja
I ship production mobile apps and scale mobile systems. 10+ years building at CyberArk, Bankwest, Conviva, and independently.
What I build:
- Full-stack mobile: Android (Kotlin), iOS (Swift), backend (Node, Python)
- On-device ML: TensorFlow Lite, inference optimization, privacy-first architectures
- Offline-first apps: sync, storage, resilience
- Mobile security: encryption, secure auth, data protection
Recent work:
- DeDup: On-device photo deduplication engine. 26% free-to-premium conversion (Play Store)
- Notes app: Cross-platform archiving, iOS + Android, offline sync
- AI Similarity: Semantic search service (web + mobile)
Industries: Mobile-first startups, privacy-critical products, AI/ML integration, scaling from MVP to production.
Best fit:
- Founding teams needing technical depth on mobile
- Companies building offline-first or privacy-centric features
- Scaling existing mobile products
- On-device ML implementation
Stack: Kotlin, Swift, TypeScript/Node, Python, Firebase, TensorFlow Lite, Room/CoreData
Availability: Contract/part-time. IST timezone.
