Nikita developed and maintained the fireflyprotocol/pro-sdk, delivering robust multi-language SDKs and API integrations across Rust, TypeScript, and Python. Over eight months, Nikita engineered features such as cross-language code generation, advanced WebSocket streaming, and secure authentication, focusing on developer experience and reliability. The work included OpenAPI-driven client generation, rigorous code quality improvements, and enhancements to error handling and diagnostics. Nikita’s approach emphasized maintainable, testable code and clear documentation, enabling faster onboarding and consistent cross-environment behavior. By aligning SDKs and APIs, Nikita improved integration clarity and accelerated client adoption, demonstrating depth in backend development, cryptography, and configuration management.

October 2025: Focused on API reliability, developer experience, and documentation clarity for the Firefly Protocol SDK. Key features delivered include a new Taker-Delay header in Trade API (with docs) and clarified expiresAtMillis semantics for LIMIT orders. Generated and aligned TypeScript and Python clients with the API changes, and updated public docs to reflect the current behavior. No major bugs reported this month; efforts centered on API definition, client generation, and documentation consistency. Business impact: improved observability and integration clarity reduce onboarding time and support effort, while ensuring accurate order expiry and delay reporting. Technologies/skills demonstrated: OpenAPI/Swagger, API design, YAML, client codegen, TypeScript, Python, documentation, cross-team coordination.

Monthly summary for 2025-08 (fireflyprotocol/pro-sdk): Delivered feature-rich WebSocket market data streaming and cross-language Account Group ID management across the API, SDKs, and docs. Key work includes enhancements to WebSocket streaming (colocated market data URL, support for multiple concurrent connections, optional groupId in streams, and AccountGroupUpdated events) and uniform group ID handling across endpoints and SDKs (OpenAPI changes, PATCH endpoint for groupId, language-agnostic client updates, and enforcement of a 6-character limit). In addition, security and quality improvements include removing sensitive account info logging. The work spanned Rust, TypeScript, Python, and documentation efforts, demonstrating strong cross-language collaboration and API design. These changes enable multi-tenant, governance-enabled access to market data, improve streaming reliability, and accelerate client integration with group-based access controls. Technologies involved include WebSocket streaming, REST/OpenAPI, and multi-language SDKs (Rust, TypeScript, Python).
