CardFly — 0-to-1 SaaS Platform & Mobile Networking Architecture

Product Vision & Market Problem

Traditional networking was fractured:

• Physical Friction: Paper business cards are static, easily lost, and require manual data re-entry into phone address books or corporate CRMs.
• Fragmented Digital Presences: Professionals maintain disparate links across LinkedIn, GitHub, portfolios, WhatsApp, and social accounts without unified branding or contact capture metrics.
• Lack of Actionable Analytics: No visibility into whether a shared contact was viewed, saved, or converted into an ongoing conversation.

CardFly solved this by providing instant micro-landing pages accessed via dynamic QR scans, backed by instant one-tap vCard downloads, lead-capture forms, and engagement metrics.

Solution

Built CardFly as a 0→1 SaaS/web and mobile product, taking responsibility across the complete product lifecycle.

• Product and market research.
• Feature brainstorming and validation.
• Product and technical design.
• Full-stack application development.
• Modular feature implementation.
• Web UI development.
• Mobile application development using React Native.
• Production deployment and operation.
• Continuous feature enhancement and optimization.
• Iterative evolution of the product based on changing requirements.
