Profile
Technical Customer Support and Customer Success specialist with 6+ years in products where a failure costs money: payments, banking, crypto and e-commerce. I take ownership of the incident end to end — reproduce it, read the API, explain it to both the merchant and engineering — and then look for the pattern behind it. I work with PostgreSQL and Metabase to turn merchant behaviour into dashboards that flag churn risk early, and with Python and Claude to automate the repetitive operations work out of existence. Looking for roles around technical products, APIs, fintech and SaaS, close to Product, Engineering and Operations.
