Herssa AI

HERSSA (Hermex Smart Support Assistant) is an AI-driven travel companion app designed to simplify and personalize the travel experience. Built as part of the Hermex ecosystem, HERSSA enables users to book flights, translate conversations, receive travel recommendations, and interact through voice, all in real-time. The goal was to merge AI intelligence, voice technology, and modern UX into a single mobile platform that feels intuitive and human-centered.

Problem

Travelers needed real-time voice and language translation in different countries.

There was no AI layer to automate flight inquiries or itinerary planning.

Integrating speech recognition and synthesis within Flutter while maintaining app performance was a major technical challenge.

Solution

I co-developed HERSSA using a modular and scalable Flutter architecture, blending AI technologies (NLP, TTS/STT) with robust mobile engineering practices.

Key implementations included:

AI Conversation Engine: Integrated a custom-built AI assistant designed by the internal AI team for flight booking, context-aware dialogue, travel itinerary suggestions, and destination recommendations.

Voice Interaction: Combined Speech-to-Text (STT) and Text-to-Speech (TTS) modules for a fully conversational user experience.

Real-Time Flight Data: Connected REST APIs to fetch live flight details, fares, and booking updates.

Offline Caching: Implemented data persistence and caching to ensure offline accessibility for itineraries and past queries.

Multi-Language Support: Integrated AI-powered translation modules supporting a wide range of global languages, enabling seamless communication for international travelers.

Technical Highlights

Architecture: Built with Clean Architecture and a feature-first structure using BLoC for modular scalability and maintainability.

AI & NLP: Integrated custom-built AI models for natural language understanding, personalized recommendations, and conversational flow.

Voice Technology: Implemented Speech-to-Text (STT) and Text-to-Speech (TTS) systems for real-time voice interaction and multi-language support.

Networking: Connected to RESTful APIs using Dio with interceptor-based caching, retry logic, and standardized error handling.

Performance: Applied lazy loading, asynchronous optimization, and widget profiling to ensure smooth user interactions.
