StreamCart is a Shopify-native livestream and shoppable video platform built to help merchants turn video content into a conversion channel. The product combined live streaming, real-time product presentation, chat engagement, and in-stream purchasing to create a more interactive storefront experience.

As Founding Engineer, I led the architecture and end-to-end development of the platform, from the live video infrastructure and merchant dashboard to storefront embed flows, analytics, and post-stream content workflows.

The goal was to help merchants move beyond static product pages by using video as a repeatable sales and content engine.

This meant building a system where brands could:

go live directly within their storefront

feature products in real time

engage viewers through chat and urgency mechanics

convert that engagement into measurable sales

extend the value of each stream through replay and clip-based content

The platform was not just about streaming. It was about turning video into a structured part of the conversion funnel.

I owned the technical design and implementation of the platform across both merchant-facing and shopper-facing experiences.

My work included:

designing the real-time livestream architecture

building the merchant live dashboard

creating storefront video embeds and “Live Now” theme app extensions

supporting real-time featured product switching and purchase interactions

implementing order attribution and analytics pipelines

enabling post-stream clip generation to extend content lifespan

optimizing performance for reliability under live traffic

A major focus of this project was making video actionable, not passive.

I built the product so merchants could use live and shoppable video as a conversion asset, not just a brand-awareness tool. During streams, merchants could feature products instantly, launch limited-time offers, surface product context beside the video, and guide viewers toward frictionless add-to-cart and checkout flows.

After the live event, the system supported replay value and automated clip generation so content could continue to drive engagement and sales beyond the original stream.

That made the platform closely aligned with modern short-form content strategy: create once, repurpose across formats, and measure performance through commerce outcomes.

The hardest part was balancing production-grade live video with commerce reliability.

Live experiences create technical pressure from multiple directions at once:

stable video delivery

synchronized storefront state

live product updates

chat activity

viewer engagement signals

purchase attribution

low-friction checkout flow

Everything had to feel immediate and polished for the shopper while remaining manageable for the merchant during a live event.

The platform used a Shopify-native, real-time architecture that could support both content delivery and conversion tracking:

Node.js, PostgreSQL, and Redis for scalable backend infrastructure

WebSockets and Redis pub/sub for real-time synchronization

Mux for RTMP ingestion and live playback

Remix-based merchant dashboard

Theme App Extension for storefront embeds and live widgets

Shopify webhooks for purchase attribution and stream analytics

I also implemented automated post-stream clip generation to help merchants extend content value after the livestream ended.

The result was a working livestream and shoppable video platform that let merchants run interactive, conversion-focused live events directly within Shopify.

Merchants could feature products in real time, track attributed purchases, monitor revenue during streams, and continue driving replay engagement after the event ended. The platform gave video a direct role in acquisition, engagement, and conversion rather than treating it as a disconnected marketing channel.

This project demonstrated how video can function as part of a full commerce system: content, engagement, urgency, conversion, and analytics all connected in one workflow.

It also showed how live and reusable video assets can support a broader content engine, especially for brands that want to scale short-form storytelling and product-led content across channels.
