I’m setting up a freelance engagement aimed squarely at pengembangan jangka panjang—this is not a quick task but an evolving build that will grow in scope and sophistication over time. The single keyword guiding every decision is “uang.” In practice that means any feature, stack choice, or workflow you suggest must ultimately improve how money is created, handled, or moved within the product. Here’s what I need from you: • A concise roadmap showing how you would structure a multi-phase build around that uang focus. • The tool-chain, frameworks, and security layers you’d pick—especially anything related to payment gateways, compliant databases, or finance-grade APIs—and why they fit. • A milestone outline that keeps the collaboration healthy, measurable, and genuinely long-term. Once we agree on direction, we’ll lock the first sprint, finalise acceptance criteria together, and move forward. If you thrive in freelance settings and enjoy shaping projects that mature over time, I’d like to see your approach.
