Project: Avis Budget Group - Wizard GUI

Description: The goal of this project was to modernize and simplify complex internal workflows by designing

and implementing a Wizard-based graphical user interface (GUI) that guided users through multi-step

operational processes. The initiative aimed to reduce user error, shorten training time, and improve

efficiency across high-volume enterprise systems.One of the primary challenges was working with legacy

systems that were powerful but difficult to use, requiring deep institutional knowledge. Processes involved

multiple interdependent steps, strict validation rules, and compliance requirements, which made usability

improvements non-trivial. Additionally, the solution needed to be scalable, intuitive, and consistent across

different user roles without disrupting existing business operations.

Key Responsibilities & Contributions:

Designed and implemented a Wizard-based graphical user interface that guided users through complex,

multi-step enterprise workflows, reducing user error and improving operational efficiency.

Translated complex business and operational requirements into intuitive, step-by-step UI flows aligned

with usability and compliance standards.

Integrated the Wizard GUI with existing Java-based backend services, ensuring seamless data flow and

minimal disruption to legacy systems.

Implemented client-side and server-side validation logic and guardrails to prevent incomplete or

incorrect data entry.

Project: Wizard GUI Application Phase 1

Description: Phase 1 focused on building the foundational Wizard-based GUI and core service architecture

for managing Avis Budget Group’s Location Database and related operational data. The goal was to provide

a structured, user-friendly interface that simplified complex data management tasks for agents while

integrating with existing enterprise systems.

Key Responsibilities & Contributions:

Developed the initial Wizard-based GUI to manage location data through intuitive, step-by-step UI

workflows.

Participated in design discussions and review meetings with Avis stakeholders; provided development

estimates based on functional complexity.

Built reusable SOA-based web services using SOAP and REST to support backend integration.
