Julian Z.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

Over the past six years, I've built and scaled web applications that actually solve problems and drive revenue. With a background in electronic engineering and over $60k in Upwork earnings, my track record speaks for itself: I focus on writing clean, scalable code and delivering software that works. Tech Stack: - Frontend: React, Next.js (SSR/SSG), Redux Toolkit, JavaScript (ES7+), HTML/CSS (Sass) - Backend: Node.js (Express & NestJS), MongoDB, PostgreSQL - UI / Styling: Tailwind CSS, Material UI, Bootstrap - Testing & Tooling: Jest, Puppeteer, Webpack - Infrastructure & Real-time: AWS Lambda (Serverless), AWS ECS, Redis, Docker. How I Work - End-to-end ownership: I handle the entire stack, from database architecture to the frontend UI. - Business-first mindset: I don't just blindly close tickets; I build solutions that make sense for your bottom line. - Quality & Detail: Reliable architecture, thorough testing, and adherence to industry best practices.
