Tihor worked across semgrep/semgrep, semgrep/semgrep-interfaces, promptfoo/promptfoo, and semgrep/semgrep-docs, building features that improved cloud integration, data ingestion, and developer onboarding. He implemented presigned URL-based S3 uploads for symbol analysis data, decoupling storage from the API server using TypeScript and Protocol Buffers to support scalable ingestion. In promptfoo, he engineered safe JSON stringification utilities in JavaScript to handle large outputs and prevent logging failures. Tihor also authored detailed documentation for AWS Bedrock integration and AI model provider selection, focusing on security and clarity. His work demonstrated depth in backend development, error handling, and cross-repository technical alignment.
