July 2025 performance summary for OpenBrain Institute core development. This period focused on delivering user-facing features, stabilizing core systems, and accelerating deployment/performance. Highlights include automated loading of the default brain region, small circuit simulation, and perType filtering for campaign queries; improvements to UI layout and campaign details; and a suite of stability fixes across brain region handling, request headers, and core data flows. Backend/DevOps enhancements include server-side ZIP builds with NodeBuffer, a CloudFront CDN deployment, Nexus cleanup, Next.js upgrade to 15.4.1, and adoption of React Query for data fetching. The combined effect: faster, more reliable simulations; improved data access via /counts endpoint; and reduced CI times due to lint/validation optimizations. This supports better decision-making, increased product velocity, and a stronger foundation for scalable experiments.

June 2025 performance summary for a developer team focused on delivering scalable data workflows, deeper EntityCore integration, and platform stability across core-web-app, entitycore, and aws-terraform-deployment. The team delivered feature work expanding data modeling and brain-region capabilities, while also stabilizing the UI, CI, and data access layers to support faster, more reliable feature delivery.

2025-05 monthly summary: Delivered major product and data-model improvements across core-web-app and entitycore. Key features include Brain Regions Tree Enhancements with ancestor propagation and new brain-region hierarchy, Rendering and Data Retrieval Improvements with a single slug-type and me-model data source, and Build Screen Bookmarking. Brain region data loading and hierarchy refactor improved data correctness and performance, while UI improvements (tree animations, dynamic explore, and library view fixes) enhanced user experience. Backend reliability was boosted by API route/facets fixes, authentication E2E tests fixes, and a corrected search results behavior. In addition, entitycore received backend enhancements like id__in filtering across read_many and asset integration including ion-channel entity type with a database migration. Technologies demonstrated include Next.js 15.3.2 server components, me-model architecture, atom-based counts, and robust testing practices. Business value: faster, more accurate queries; better auditability; and increased stability and scalability across data-intensive research workflows.

April 2025 performance summary: Delivered substantial UX improvements, admin workflow enhancements, data model and API enhancements, stability fixes, and a solid foundation for testing across core-web-app, entitycore, and aws-terraform-deployment. Achievements include user name display in the side menu with a fallback to username; admin workflow to add project members without invites with a two-tab Virtual Labs listing; support for adding a member during project creation; adoption of PNPM with package synchronization to stabilize the development environment; and introduction of density metrics endpoints (neuron-density, bouton-density, syspases-per-connection) along with project-scoped entity fetching and related UI/data queries. In parallel, refactors and UI improvements (entity core mapper refactor, thumbnail previews, public IDs) accompanied stability fixes to naming, project listing behavior, and migration issues. Overall, these changes deliver tangible business value by improving onboarding, collaboration, data analytics capability, and system reliability, while strengthening testing foundations and implementation discipline across three repositories.

March 2025 was anchored by delivering robust user data persistence and subscription flexibility, while enabling scalable virtual lab capabilities and stabilizing core surfaces. Notable feature deliveries included: 1) User Data Persistence and Session Management — added an IndexedDB-based user journey store and robust session URL handling to improve offline resilience and session continuity; 2) Subscription Management and Plans Removal — introduced subscription workflows and plan removal to support evolving pricing and product changes; 3) Virtual Lab enhancements — enabled multi-Lab support, vlab IDs, and enhanced responses (user counts, reconstruction morphology) plus UI refinements (default lab naming via username). These efforts collectively improve user onboarding, data integrity, and platform scalability across core web-app and lab services.

February 2025 — Core Web App and AWS Terraform Deployment: Accelerated CI/CD, hardened privacy/compliance, improved observability, and strengthened cloud infrastructure. Delivered parallel test execution to speed up CI, integrated Mailchimp signups, expanded privacy-related pages and routing, and reinforced deployment environment handling with analytics support. Also completed a strategic migration to AWS ECR for container images, added Redis caching via ElastiCache, and tightened secret management and deployment guardrails across the core web app and Virtual Lab Manager.

January 2025 performance summary for openbraininstitute/core-web-app. Delivered key user experience enhancements for the Virtual Lab, enhanced collaboration workflows, extended data capabilities with a new EntityCore API client, and improved reliability and documentation.
