I don't just build things — I solve problems and deliver measurable outcomes.
QR Scan Contest App
Problem
Local café losing customers after the first visit — no loyalty system, and existing platforms cost $100+/month.
Solution
Built a weekly QR scan contest in Glide: customers scan each week, track their progress, and unlock a free reward after 4 visits.
Result
65% of first-time visitors returned within 4 weeks. Repeat visit rate up 3x compared to before launch.
Client Portal Dashboard
Problem
Agency spending 10+ hours/week manually updating clients on project progress via emails.
Solution
Developed a branded client portal with real-time project status, file sharing, and invoice tracking.
Result
Saved 40 hours/month and improved client retention by 35% in the first quarter.
SaaS Conversion Landing Page
Problem
Startup getting traffic but converting at under 1% — product was good but the page wasn't selling.
Solution
Redesigned the entire landing page with clear value proposition, social proof, and strategic CTAs.
Result
Conversion rate jumped from 0.8% to 4.2% — a 5x lift — within the first month.
QR Scan Contest App
Problem
Local café losing customers after the first visit — no loyalty system, and existing platforms cost $100+/month.
Solution
Built a weekly QR scan contest in Glide: customers scan each week, track their progress, and unlock a free reward after 4 visits.
