Backend engineer with 4+ years building production systems in Node.js, TypeScript and PostgreSQL, with a focus on integrations and data handling under real constraints. Most of my work sits where systems meet: third-party APIs, event pipelines, and the audit and access-control layer around sensitive data. I built a document digitization system on Azure for an international organization where consent, retention and access control shaped the data model rather than being bolted on afterwards. I also built an asynchronous processing pipeline on RabbitMQ for a platform serving 90,000+ users, handling retries, failure states and monitoring. On the performance side, I took a production application from roughly 50 second page loads down to 2 or 3 seconds through query and data-access work. On the frontend I work in React and Next.js, and I've shipped production apps in Vue. I can immediately be productive on backend, data model and integrations. I work well against a fixed delivery window and I'm comfortable reviewing an inherited codebase and saying plainly what should be kept, rewritten or cut.
