PROFILE

Mariano Nicolini

Mariano Nicolini developed and enhanced backend systems for the PsycheFoundation/psyche repository, focusing on reliability, maintainability, and developer experience. He implemented batch processing resilience with retry logic, prioritized transactions based on user fees, and improved onboarding through detailed Ubuntu and Docker documentation. Mariano introduced a null model optimizer in Rust to accelerate test cycles, updated Bash scripts to scale airdrop distributions, and established a local telemetry stack using OpenTelemetry, Prometheus, and Grafana for observability. His work included code cleanup and refactoring, ensuring consistent error handling and reducing technical debt, resulting in a robust, well-documented, and scalable backend infrastructure.

Jul 1, 2025

July 2025 monthly summary for Psyche project. Key features delivered: Local Telemetry Setup and Monitoring to enable metrics visualization and debugging in the local development environment. Major bugs fixed: None reported this month. Overall impact and accomplishments: Established a local observability stack (OpenTelemetry collectors, Prometheus, Loki, Grafana) to export telemetry data from the local testnet and training scripts, enabling dashboards and faster issue diagnosis. This groundwork supports proactive monitoring, alerting, and performance tuning in future sprints. Technologies/skills demonstrated: OpenTelemetry instrumentation, metrics backends (Prometheus), logging (Loki), visualization with Grafana, and local-dev observability pipelines.

Nov 1, 2024

November 2024: Delivered key resilience and onboarding improvements across two repositories, focusing on batch processing reliability, cost-aware prioritization, and Ubuntu onboarding. Implemented a retry module for Batcher, integrated into gas price fetch, user balance fetch, nonce retrieval, and batch upload to S3, and added documentation detailing the max-fee priority queue and batch finalization algorithm. Added Ubuntu-specific setup instructions to Psyche project README, covering driver installation, CUDA libraries, libtorch, environment variables, and Rust/just tooling. Removed redundant WebSocket reconnect config to simplify operation. These changes improve stability, throughput, and developer onboarding, while clarifying how user fees influence batching behavior.
