🎩 I solve complex operational problems, which has led me to wear a lot of hats. I collected them across early-stage startups, years of freelancing, and enterprise. That range made me the person who can walk into an unfamiliar mess, find the underlying structure, and make it work. I solve the problem, then build the systems so it stays solved. 🛠️ By day, I lead Premium Support for the highest-value customers on one of the world's largest work marketplaces. My background runs across marketplaces, SaaS, payments, and eCommerce, and the work sits where customer operations meets the commercial side: product operations, revenue and retention, and the enablement that keeps high-value accounts growing. It runs across four pillars: - Solution architecture: own platform-critical launches and P0 escalations end to end, and turn customer insight into prioritized product and self-service improvements. - Enablement: stand up commercial offerings and the training behind them, and serve as the SME delivering enablement from new hires up to Directors. - Revenue and data operations: build the dashboards, KPIs, and AI-assisted workflows on which decisions are made, and automate reporting for leadership visibility. - Retention: lead retention across premium accounts and run churn rescue on the at-risk ones, pairing commercial fit with the unit economics that justify the save. On the ground that looks like reconciling an enterprise account tangled in billing complexity and keeping the relationship intact, investigating a flagged high-value account and protecting the platform without disrupting legitimate business, and building the commercial case that turns a client on the fence into an easy save. Before this, I spent years as the single operations owner for a dozen SMB and startup clients across SaaS and eCommerce, most of them long-term repeat work (100% job success, top 3% of talent). I took a Swiss wholesaler's online store from a few thousand to around $70K in revenue and built a zero-plugin data model for its 60K+ SKU catalog. I shipped 20+ complex feature enhancements for an eCommerce startup while running their backend supply chain and built an EdTech quizzing platform end-to-end, from problem discovery and MVP through pricing, billing, and go-to-market, growing it to 1,300+ users organically. 🏆 Two awards along the way: one for entrepreneurship, one for owning outcomes. Track record: - Shipped a new payment method at zero incremental cost that drove $1.5M in volume quarter over quarter. - Enabled a commercial offering that hit 34% QoQ growth with 39% net-new clients. - Cut internal research time by roughly 80% by pairing AI tooling with AI-enabled SQL querying. - Automated a recurring leadership report from hours down to minutes. - Retained $3.3M in lifetime value in H1 2026 through one of the programs I designed and led. 📚 MBA candidate. Before that, I trained and was licensed as a doctor (MBBS), which is where the instinct comes from: read the symptoms, find the root cause, don't just treat the surface.
