PROFILE
Lucas Bacciotti
Over twelve months, Luca Baciotti engineered cost management and reporting features for the project-koku/koku repository, focusing on multi-cloud environments. He enhanced cost visibility and accuracy by refactoring SQL and Python logic, introducing granular metrics, and optimizing database queries for AWS, Azure, GCP, and OpenShift. Luca centralized CI/CD pipelines using Tekton and improved DevOps workflows, while also implementing robust error handling and feature flagging for safer deployments. His work included expanding currency support, refining API endpoints, and streamlining data models to reduce maintenance overhead. Using Django, SQL, and Python, Luca delivered reliable, maintainable solutions that improved reporting precision and operational efficiency.

Aug 1, 2025Month: 2025-08 | Repository: project-koku/koku. Focused on deprecation messaging for Azure v1 reports. Implemented a log-level change from error to warning and added a clear message guiding users toward modern report schemas. This reduces log noise, improves user guidance during migration, and prepares the product for deprecation of Azure v1 reporting. No other high-impact features or bug fixes were recorded this month.

Jul 1, 2025July 2025 delivered targeted enhancements to improve reporting accuracy, cost visibility, and reliability across cloud providers. Key work includes dynamic tag-key filtering in the Daily Summary Report via a Common Table Expression to fetch enabled keys for AWS/Azure/GCP and OCP, and adding vm_kubevirt_io_name to the enabled list; CZK currency support with corresponding updates to currency lists and exchangerates migration; fractional-hour VM cost calculations for tag-based usage with refactored SQL/Python logic and updated tests; and a stability fix for month-boundary VM summaries by adjusting the query to use the second-to-last day with valid VM data. These changes reduce data gaps, broaden currency coverage, and improve cost precision and test resilience, delivering measurable business value for multi-cloud cost visibility and reporting reliability.

Jun 1, 2025June 2025 — Key accomplishments in project-koku/koku included strengthening build isolation, simplifying cloud-provider strategy, and boosting dashboard performance. Delivered a Tekton pipeline enhancement to run builds with a dedicated service account, deprecated IBM Cloud in favor of OCI with a clean migration, and reduced CI noise by gating Jenkins tests behind a PR label. Expanded key retrieval for more comprehensive queries and delivered Grafana dashboard performance improvements with pre-aggregated metrics, resulting in faster dashboards and lower query load. These changes collectively improve security, maintainability, and business analytics capabilities while reducing operational overhead.

Mar 1, 2025March 2025 – Project-koku/koku: Focused on accuracy, governance, and cost visibility. Delivered three major items: (1) date delta calculation fix for negative time scopes to ensure the relative delta is exactly one month, eliminating misaligned period estimates in reporting; (2) a feature-flagged API path for the new source status retrieval method with backward-compatible POST routing and tests validating flag behavior; and (3) a cost-model enhancement introducing cluster_core_cost_per_hour and integrating it into configuration and SQL queries to account for cluster-level core-hour usage. These changes improve data accuracy, enable safer feature rollouts, and provide more precise cost visibility for multi-tenant deployments. Technologies demonstrated include Python backend work, feature flag patterns, test-driven development, and SQL-based cost modeling. Business value: more reliable period reporting, controlled feature experiments, and improved cost accounting for cluster usage.

Feb 1, 2025February 2025: Implemented cost visibility enhancements for OpenShift VM costs in the Koku project to improve cost governance and transparency. Added new cost-related fields to the OpenShift VM provider map and introduced detailed cost breakdowns for distributed resources (platform, worker, network, and storage). Included a unit test validating accurate reporting of distributed costs in the virtual machines endpoint, enabling precise chargeback/showback and better resource planning. This work strengthens cost accuracy, reduces manual reconciliation, and sets the groundwork for future cost dimensions across VM resources.
