PROFILE
Piotr-figwer-reef
Piotr Figwer developed and maintained the backend for the ComputeHorde repository, delivering features that improved authentication, job processing, and data integrity. He implemented JWT-based stateless authentication, centralized receipts and collateral management, and enhanced reward distribution logic, all while ensuring robust API integration and CI/CD workflows. Using Python, Django, and AWS, Piotr refactored legacy systems, introduced asynchronous processing with Celery, and optimized database migrations for reliability and scalability. His work addressed complex distributed systems challenges, streamlined deployment, and improved traceability. The depth of his engineering is evident in the breadth of features delivered and the consistent focus on maintainability.

Jul 1, 2025July 2025 performance summary for backend-developers-ltd/ComputeHorde: Key feature delivery, reliability improvements, and data integrity enhancements across the Compute Horde workflow. Delivered dynamic split distribution via Compute Horde Dancing with new messaging types, miner validator integration, a scoring mechanism, and accompanying migrations and tests. Added a periodic Celery task to fetch and trust miner manifests, centralizing manifest generation to miners for enhanced reliability. Fixed manifest polling to consider only the latest manifest per executor class and added tests to prevent duplicates. Strengthened CI reliability with SSH key reuse for fallback tests and stability improvements for GPU/test outputs. Implemented a MinerManifest cleanup migration to maintain data integrity and added executor disconnect handling to mark jobs failed when executors disconnect prematurely. These changes improve efficiency, fairness, data accuracy, CI reliability, and overall system resilience.
