Product Overview

SyncSparq manufactures NFC-embedded smart business cards and software. When tapped against any modern smartphone, it opens an interactive digital identity with 1-click contact saving, social links, and lead capture. As Full Stack & E-Commerce Architect, I built the web platform, NFC URL redirection engine, and payment webhooks.

Bottlenecks Solved

In-Person Tap Latency: In face-to-face networking, a profile that takes 4 seconds to load causes awkwardness. The target was sub-1.2s cold loads on standard 4G mobile cellular connections.
Dual-OS NFC Antennas: Apple iOS CoreNFC and diverse Android antenna geometries require specific NDEF URI records to avoid triggering native security warnings.
