Orestis Balas developed and maintained core collateral and settlement APIs for the fireblocks-network-link repository, focusing on robust backend workflows and compliance-driven features. He designed and refactored TypeScript and Node.js services to support end-to-end collateral management, withdrawal approval flows, and Travel Rule compliance, leveraging OpenAPI Specification for contract alignment and validation. His work included implementing flexible balance structures, country code standardization, and deposit address lifecycle management, while enhancing test coverage and code quality through disciplined linting and modularization. By addressing pagination, timestamp validation, and error handling, Orestis improved reliability, maintainability, and integration safety for partners and downstream services.
