Vendorful
LiveView sourcing suite delivering sub-second RFP workflows and US$ 4.7 M in funding.
The Story
As Lead Software Engineer, I spearheaded Vendorful's migration from a client-side React UI to server-rendered Phoenix LiveView, architecting real-time channels for live RFP/RFQ events, integrating Oban for background job processing, and establishing GitHub Actions CI/CD with AWS auto-scaling—delivering an enterprise-grade sourcing platform with sub-second response times and 99.9% uptime.
The Problems We Tackled
Every great solution begins with understanding the core challenges that need to be addressed.
Challenge 1
Migrating a rich, client-side React application to server-rendered LiveView without UX regressions
Challenge 2
Achieving sub-second latency under high concurrency for complex sourcing workflows
Challenge 3
Orchestrating real-time reverse auctions and supplier interactions via LiveView channels
Challenge 4
Ensuring reliable background processing and observability at enterprise scale
How We Solved It
Strategic approaches and innovative solutions that transformed challenges into opportunities.
Solution 1
Rewritten core UI in Phoenix LiveView, leveraging its diff-driven DOM updates for instant interactions
Solution 2
Built optimized LiveView components and caching layers to sustain sub-second RFP workflows
Solution 3
Integrated Oban for robust async tasks (report generation, notifications) with PostgreSQL
Solution 4
Implemented blue-green deployments via GitHub Actions and tuned AWS auto-scaling for 99.9% uptime
The Outcome
Measurable impact and transformative results that exceeded expectations.
