BullsOf2028
Multi-chain market data with repeatable rankings and history.
The problem
Market data is fragmented across providers and chains. BullsOf2028 organizes asset discovery and historical views around consistent eligibility and ranking rules.
What I built
Built and deployed the market intelligence application, including scheduled ingestion, provider integrations, deterministic rankings and historical snapshots.
Architecture at a glance
A simplified view of the main application components.
- 01
Providers
CoinGecko, DexScreener and GoPlus APIs
- 02
Pipeline
Scheduled ingestion and data reconciliation
- 03
Storage
Cloudflare D1 and historical snapshots
- 04
Experience
Ranked assets, categories and history
Engineering decisions
Retain historical snapshots
Snapshots make it possible to inspect how assets and categories change over time.
Reconcile incoming data
Provider ingestion and reconciliation support a consistent application view across chains.
Technology
Current outcome
Live and receiving website traffic. Covers Solana, Ethereum, BNB Smart Chain, Base and Robinhood Chain.
What I would improve next
Future work should make freshness and provider coverage easier to inspect alongside each result.
