Senior Frontend Developer at GanttPro who rebuilt project import and developed a Board view for large projects.

Message

At GanttPro, I rebuilt project import from Excel and MPP files as a five-step wizard, with an AI model mapping file data and keeping it consistent between steps. The new flow made parsing and project preparation 7–10 seconds faster on the client and backend.

I also developed a Board view from scratch for projects with 20,000+ tasks, including grouping, sorting, and card updates without reloading the board. My earlier work includes React chart and dashboard screens at Oxagile, plus a Vue.js video-conferencing application using WebRTC.
