At SEO Disrupt, I designed and maintained REST APIs for internal services using Node.js and TypeScript. I reworked PostgreSQL schemas through Prisma, added role-based JWT authentication, and integrated third-party services and payment APIs.
Before that, I built React, Next.js, and TypeScript interfaces at QLab, including responsive layouts and user profile features connected to the API. I also worked with the Node.js and PostgreSQL backend at the integration level.
On independent projects, I built PayForge, a payment gateway sandbox with idempotent postings, HMAC-signed webhooks, and safeguards for concurrent transactions. I’ve also worked on a Rust e-commerce platform focused on preventing duplicate sales under concurrent orders, and I’m developing TradeOS, a multi-tenant trading platform.
