Message

At Slash Finances, I led architecture and delivery of Python and TypeScript loan-management, payment, and back-office services. I shipped direct-debit and international-payment capabilities with asynchronous provider integrations that reconcile reversals and out-of-order callbacks.

I independently built EduCore, a multi-tenant school-management SaaS, with transactional event processing and safeguards against partial enrollment states. Across my work, I’ve shipped production products in fintech, analytics, education, and logistics, including APIs supporting 50,000+ concurrent users.
