Growth Product Manager at Jspreadsheet, growing leads while cutting paid spend by 60%.

At Jspreadsheet, I grew monthly leads from an average of 190 in 2025 to 340 in Q3 2026 while paid spend fell by 60%. I built funnel tracking through closed sales and ran more than 1,400 growth experiments across 19 channels.

At Personia AI, I built the acquisition pipeline and the evaluation pipeline for synthetic studies. I also co-founded Manasync, a tournament product I designed and built, which grew to 3,000 monthly active players and more than 500 organizers in its first year.
