My Portfolio

AIS Chatbot Callflow Project

Led the development of a comprehensive Callflow management system for AIS's chatbot platform. This project involved designing conversation flows that guide customers through various service inquiries, from bill inquiries to service cancellations. I utilized Genie Dialog Design Tool to create intuitive conversation paths and orchestrated the entire project using Azure DevOps.

Architecture & Structure: The system was organized into multiple repositories for better maintainability—Web Admin portal for configuration, Static Web App for user-facing interface, and Core Engine for processing logic. All components were managed through Azure DevOps with automated CI/CD pipelines to ensure quality and rapid deployment.

Project Management & Quality Standards

Owned responsibility for project governance and quality assurance across multiple initiatives. I established and enforced standardized processes that ensured compliance with international standards while maintaining team efficiency.

• ISO 29110 Implementation: Served as Project Manager to establish standardized software development processes. This framework helped the organization develop reliable, repeatable project workflows.
• ISO 27001 Document Control: Acted as Document Control Coordinator managing all system documentation to meet information security standards. This included creating version-controlled documents that could be audited at any time.
• System Documentation Lifecycle: Created critical documents throughout project phases—PLANNING, SRS, SOW, and UAT to ensure clarity and traceability at each stage.

• Analytics Backend: Developed Node.js services to feed data to Elasticsearch for real-time dashboards and reporting.

Telephony & IVR Systems

Managed end-to-end development of Interactive Voice Response (IVR) and voicebot systems for telecommunications clients. I designed call flows that intelligently route customer inquiries, reducing wait times and improving service satisfaction.

• Callflow Design: Designed sophisticated call flows to handle diverse customer scenarios with natural progression.
