king with Node.js, NestJS, and TypeScript, and I think my background is a really solid match for what you're looking for. Over the years, I've built and scaled systems across fintech, ERP, and gaming. Recently, I've been heavily focused on refactoring complex enterprise logic, scaling microservices with tools like NATS, RabbitMQ, and Redis, and setting up proper observability with Grafana. I also rely heavily on AI tools like Cursor and Claude Code in my daily workflow to speed up refactoring, testing, and delivery without dropping code quality. What makes me a great fit for this specific role is that I like taking end-to-end ownership — whether that's designing modular services, optimizing database queries so they actually run fast, or cleaning up messy codebases.
