Collaborated with D-Side Group and later InWink to build and maintain a large-scale B2B web store and mobile app for Carrefour events and fairs across Europe.
- Developed a comprehensive fair management system for D-Side Group, allowing exhibitors to reserve stands and purchase accessories (eg. chairs, refrigerators), with automated PDF invoicing and Excel reports
- Engineered end-to-end solutions for event logistics, including badge generation, a custom iPad badge scanning app for entrance control, and real-time reporting for attendee headcount and live sales metrics
- Built a React Native mobile app enabling visitors to place orders by scanning product QR codes at events, tightly integrated with a React.js web platform backed by a Node.js + GraphQL backend
- Developed several customer support and ticketing systems, including:
- Email-based support system
- Real-time chat integrated into the website
- SMS integration for quick, on-the-go support
- Created a web page builder that allowed exhibitors to customize the appearance of their section on our store in accordance with their brand
- Integrated our B2B commerce platform with InWink's existing event system using their flexible APIs, including a customized UI for seamless embedding within their website and mobile app
- Ensured high data accuracy while managing complex, country-specific spreadsheet and reports, which was critical for aligning with Carrefour's varied workflows across different European countries
- Managed the infrastructure and personally wrote the majority of the platform’s codebase, only overseeing another developer during the initial phase to meet strict event launch deadlines
- Worked on several other projects led by the team at faire.xyz, most notably:
- Integrated AI into the Made With You platform
- Developed our in-house crypto currency trading bot
I skipped a large number of features that I was responsible for, but I'll gladly mention them in an interview.
