About
I've built production-grade enterprise systems for Nefentus, CollectWise, Chef Admin, and ClickSeer, including multi-tenant crypto invoicing, financial recovery, restaurant management, and salon platforms.
At Nefentus, I architected a crypto invoicing platform with native wallet generation, shareable payment links, role-based access, and real-time sales analytics. At CollectWise, I built automated debt-settlement workflows, Stripe payment integrations, Firebase Cloud Functions, and PDF invoicing tools.
I work across Java, Spring Boot, React, Angular, Node.js, React Native, Web3, and cloud tooling to take web and mobile products from concept through production.
