Ashish Kumar

• Developed a full-stack airport retail media platform integrating real-time flight operations, passenger-flow intelligence, and dynamic digital advertising across five role-based interfaces.
• Architected an event-driven backend with AODB, IATA AIDX, and ACRIS data adapters to normalize airport information and enable real-time updates using WebSockets.
• Implemented an explainable AI-assisted advertisement decision engine with audience matching, campaign targeting, deterministic validation, and evidence-based decision logging.
• Built interactive dashboards for airport administrators, retailers, media managers, and airlines, featuring live analytics, campaign management, operational monitoring, and inventory scheduling.
• Designed a digital signage simulator with dynamic advertisement delivery, QR-based promotional redemption, and synchronized campaign analytics.
• Developed a centralized flight simulation engine supporting delays, gate changes, and accelerated time-based scenarios.

• Built a telecom support app with Next.js and FastAPI; used Google ADK to route account, billing, and connection questions through authorized service tools.
• Added account access checks and customer approval before case creation; stored action receipts in SQLite to prevent duplicate cases after retries or a new sign-in.
• Connected HTTP services and a legacy XML adapter, with response validation, timeouts, and request traces for failures and handoffs.
• Verified eight customer scenarios, 166 backend tests, and 13 frontend tests; packaged the web app, API, and sample services with Docker Compose.

• Built a full-stack attendance system connecting MTCNN/FaceNet inference pipelines to the backend via REST, achieving 92% face-recognition accuracy with sub-500 ms response times under live load.
• Designed a three-tier RBAC system (Admin, Faculty, Student) with fine-grained permission logic, cutting manual attendance recording time for a 60-student cohort by approximately 80%.
• Secured the application with stateless JWT authentication and bcrypt password hashing; wrote automated Postman test suites with zero unauthorized-access incidents during testing.
