Uncle Sam’s Corndogs: Bringing Authentic American Street Food to London

Born from a passion for American street food, Uncle Sam’s Corndogs delivers the iconic fairground classic to the heart of London. Known for its golden, crispy batter and perfectly cooked all-beef franks, the brand has quickly carved out a niche in London’s vibrant food market scene.

As a founding team member and Lead Digital Content Creator, I’ve played a pivotal role in shaping Uncle Sam’s Corndogs’ identity both on the ground and online. From designing the visual brand to building a social media presence, my work has focused on engaging audiences and driving footfall at every event.

To streamline on-site operations and modernize order management, I also architected and developed a custom Point-of-Sale (POS) system. Built with Flask and Supabase, it features:

Real-time Order Processing: Orders are captured instantly, stored persistently in Supabase, and displayed on a ticket board for kitchen staff.
Admin Dashboard: Secure PIN-protected interface for viewing, editing, and deleting orders, with multi-delete and date filtering.
Reporting & Analytics: Interactive sales charts, popular item breakdowns, hourly order trends, and CSV export support.
Payment Integration: Seamless SumUp integration to trigger contactless payments directly from the POS interface.

Key responsibilities and contributions include:

Content Strategy & Creation: Developed dynamic video and photo content across TikTok and Instagram, showcasing team culture, behind-the-scenes footage, and the art of making our signature corndogs.
Brand Identity Design: Designed visual assets including menus, banners, and merchandise, capturing the bold Americana aesthetic that defines the brand.
Market Expansion: Spearheaded launches into key London locations including Brick Lane and Hackney Wick, increasing visibility and driving customer engagement.
Storytelling & Community Building: Created relatable, story-driven content that highlights the people behind the brand and fosters a growing community of loyal customers.
On-Site Operations & Sales: Managed front-line operations at major food markets and festivals, balancing customer experience with efficient service delivery.

Impact: Uncle Sam’s Corndogs has become a recognizable name on the London street food scene, celebrated for both its nostalgic taste and engaging digital presence. The custom POS system has greatly improved order accuracy, speed of service, and provided actionable insights that continue to shape our growth strategy.
