A B2B marketplace aggregating hotel-supply vendors (HD Supply, US Foods, Amazon and more) for price comparison and streamlined procurement across US hospitality businesses. Acquired by Inn-Flow (USA) in May 2026.
- Built and maintained large-scale web-scraping systems in Python (Scrapy, Patchright, Playwright) to extract vendor data across 20+ vendor sites, using residential proxies and techniques to bypass Cloudflare, Akamai, PerimeterX and other bot/CAPTCHA protections.
- Built a client-onboarding pipeline, orchestrated with AWS Lambda and Step Functions, that scraped and structured clients’ past purchases, order guides and brand-standard products, onboarding 100+ hotels onto the platform.
- Developed and deployed (on ECS, with a staging environment) backend microservices in Node.js/TypeScript powering real-time vendor integrations across 8 vendors: placing orders, fetching live pricing and stock, replicating cart state and tracking order status without public APIs, using auth tokens, cookies and custom scraping-based connections.
- Worked with AWS (Lambda, SQS, Step Functions, ECS, EC2), NATS and MongoDB for backend infrastructure.
- Leveraged Claude AI, including via the Playwright MCP, to accelerate scraper development and bot-detection bypass techniques, and to build frontend pages for internal tools.
- Used Sentry for error monitoring; worked across GitHub and GitLab for version control and CI/CD.
