Junaid Afzal — Software Engineer (Flutter, React Native & NestJS)

Cross-Platform Mobile Apps

I build production-grade Flutter and React Native apps for iOS and Android — clean architecture, smooth UI and store-ready releases.

• Flutter & Dart (Riverpod, Provider, Clean Architecture)
• React Native (TypeScript, Android & iOS, performance tuning)
• Firebase & Integrations (Auth, Firestore, FCM, REST with token refresh, RevenueCat)

Backend & Microservices

Scalable NestJS backends: well-designed REST APIs, microservices and real-time features that mobile clients can rely on.

• NestJS & Node.js (REST APIs, microservices, Swagger / OpenAPI)
• Databases & Caching (MongoDB, Firestore, Redis)
• Auth & Real-time (JWT, WebSockets, notifications)

AI & Real-Time Features

Practical AI inside real products: speech, LLM and retrieval pipelines, plus low-latency audio and video experiences.

• LLM Pipelines (GPT-4o, Whisper STT, ElevenLabs TTS)
• RAG & Chatbots (Firestore-grounded retrieval, Cloud Functions)
• Real-time Media (LiveKit, WebSockets, FFmpeg)

Web3, Web & DevOps

Solana wallet integrations, React dashboards and CI/CD pipelines that carry features from commit to production.

• Web3 (Solana wallets, Hyperledger Fabric)
• Web Dashboards (React, Tailwind CSS)
• CI/CD (GitHub Actions, automated builds, Docker — learning)
