I designed and built an end-to-end enterprise platform (LocXpress) used by a translation company to manage its full operational workflow - including sales, vendor management, and project management. What makes my experience unique is ownership: I built the entire system independently, starting from requirements analysis and system design, through backend and frontend development, all the way to infrastructure setup and production deployment. My work includes: • Designing scalable backend systems using Node.js and Express • Building multi-application architectures (client app, vendor portal, backend API, shared modules) • Implementing secure authentication, role-based access control, and API validation layers • Designing file storage systems using S3-compatible storage (Cloudflare R2) • Building async processing systems using Redis and BullMQ • Containerizing applications with Docker and managing deployments using CI/CD pipelines • Setting up production environments with Nginx and VPS infrastructure I also built an automation service that processes incoming tasks in real-time using IMAP, background workers, and browser automation (Puppeteer), focusing on reliability, fault tolerance, and long-running operations. I’m particularly interested in backend architecture, system design, and building scalable systems that solve real business problems. less -
