At Visible-Box / Tummee.com, I architected time-windowed, country-specific discounting workflows for IYD that generated $50K+ in a single-day test run. I also implemented tiered subscription pricing that increased AI-driven revenue by 30% while reducing infrastructure costs.

I built an end-to-end gift subscription workflow with cross-user subscription linking, SendGrid notifications, and round-robin allocation. I also added configurable pricing tiers for business rules.

Earlier at Visible-Box / Tummee.com, I developed subscription and analytics systems, including a dashboard with LLM-powered insights. I introduced Stripe Setup Intents for backup-card retries, reducing renewal payment failures by 20%, and built a Python and Flask analytics microservice during my internship.
