using TypeScript and modern frameworks.
Develop and maintain
backend APIs and services
that provide structured blockchain data to Startale’s products.
Model and manage relational data
with PostgreSQL, ensuring efficient schema design and query performance.
Use and extend
indexing frameworks
(e.g., The Graph, Subsquid, or custom-built solutions) to support diverse on-chain data needs.
Ingest and process blockchain events, transactions, and states
into consistent, queryable datasets.
Build and maintain
monitoring, alerting, and observability tools
for indexer and service reliability.
Collaborate with cross-functional teams to design
data pipelines and integration layers
for on-chain applications.
Continuously
optimize ingestion throughput, data accuracy, and scalability
under production workloads.
Requirements
TypeScript Backend Development
