I contributed to the development of large-scale web platforms across tourism, finance, and
security sectors. My focus was on creating intuitive user interfaces and robust business
functionality tailored to diverse user needs.
Key projects included:
Tourism Platform — Designed a user-friendly interface for travelers and a powerful
dashboard for property owners, enabling booking management, analytics, and customer
communication.

medium-sized enterprises, streamlining financial operations, improving access to export
support tools, and ensuring transaction transparency.
AI-Powered Security Platform — Developed an innovative system leveraging artificial
intelligence to assess risks, respond to incidents, and provide advanced protection for
organizations.
I was involved in all stages of development — from architecture planning and UI creation to
API integration and deployment. Collaborated closely with designers, backend developers, and
product managers to ensure performance, responsiveness, and adherence to UI/UX best
practices.
