NFC Music &
Fan Experience Platform

A platform that reinvents how artists sell and fans collect music. Artists press NFC-enabled cards for their releases; a fan taps one to a phone and an encrypted microsite opens their tracks, videos and extras — the best of physical and digital, with deep tap-level analytics and an editorial music publication built in.

The Challenge

A brand-new product, built from scratch.

The software didn't exist — every part had to be invented. Artists needed to reclaim revenue that streaming erodes; the tap-a-card experience had to feel effortless, not gimmicky; and traffic would be wildly unpredictable, demanding a system that stays real-time with zero downtime while remaining cost-effective.

The Solution

Encrypted taps on a serverless spine.

A consumption-based serverless architecture scales up for spikes and down when quiet. Each NFC card maps to a real-time decryption algorithm, so its microsite opens only on a genuine tap — never a copied URL. On top sit five modules: the public publication, artist onboarding, artist portal, admin portal, and the fan mobile app.

Inside the product

tap, listen, collect.

Engineering deep-dive

Breaking past the API gateway ceiling.

As the feature set grew, we hit a hard platform limit: each gateway allows only 100 function registrations. Versioning or splitting endpoints both meant sweeping changes and full regression. Instead we built a bridge proxy gateway that routes by custom per-service policy to secondary gateways — giving effectively unlimited function endpoints with zero downtime, near-zero maintenance, and no premium-tier cost.

Outcomes

faster to ship, cheaper to run.

~60%

lower infrastructure cost vs. a serverfull architecture, via consumption-based serverless scaling.

+40%

overall delivery gains from AI-assisted engineering (up to 60–70% on execution tasks).

−30%

fewer feedback loops via Front-End Driven Development with stakeholders.
