Chain API
No-code Airnode oracle builder slashing setup from 2 h to 10 min for 250+ providers.
The Story
As Senior Software Engineer, I led end-to-end architecture of the Elixir/Phoenix backend and Next.js dashboard, authoring a Terraform-style scaffold generator that transforms user inputs into Airnode config files—cutting oracle setup from ~2 hours to under 10 minutes. I also built real-time health-metrics reporting via WebSockets + PostgreSQL and implemented GitHub Actions → AWS blue-green deployments, reducing release downtime to under 30 seconds.
The Problems We Tackled
Every great solution begins with understanding the core challenges that need to be addressed.
Challenge 1
Automating a traditionally manual, 2-hour Airnode deployment workflow into an intuitive no-code experience
Challenge 2
Ensuring compatibility across diverse legacy APIs and multiple EVM networks
Challenge 3
Maintaining high availability and observability for decentralized oracle services
How We Solved It
Strategic approaches and innovative solutions that transformed challenges into opportunities.
Solution 1
Engineered Elixir/Phoenix microservices to orchestrate on-demand Airnode provisioning with auto-generated Terraform JSON configs
Solution 2
Developed a React/Next.js one-click wizard for seamless API-to-oracle binding and multi-cloud (AWS/GCP) deployment
Solution 3
Integrated WebSockets + PostgreSQL for real-time node health and latency dashboards, backed by CI/CD blue-green pipelines
The Outcome
Measurable impact and transformative results that exceeded expectations.
