Jack Wong
@jackwong01
I build growth-focused full-stack products and automation that cut CAC and churn.
What I'm looking for
I’m a growth-focused full-stack engineer who ships production software tied to measurable business outcomes. I use Python and JavaScript/TypeScript across React, Node.js, and pragmatic no-code tooling to deliver MVPs, internal systems, billing flows, and acquisition infrastructure quickly.
Recently, I scaled an AI chat product from 0 to 4,200+ registered users in 90 days, achieving 34% 30-day retention without paid ads. I’ve also cut CAC by 38% (from $48 to $30) by rebuilding landing pages and improving search and retargeting, while lifting organic conversion from 1.2% to 3.7%.
I combine conversion optimization, funnel analysis, and automation to remove bottlenecks—automating a 40-hour-per-week workflow down to 2 hours with Python + Airtable at 99.8% accuracy. I’m equally effective at landing critical bug fixes and API integrations under tight timelines, delivering client products in 2–3 weeks.
