2026-01-21 Weekly Executive Report – Sustainability
Highlights
Device & Gateway Notifications, Visibility & Reporting
Enhanced the Device/Gateway Notification Lambda to send daily status reports regardless of state changes, ensuring system administrators have consistent visibility into device and gateway health, not just exception-based updates.
Implemented functionality to mark AQS sites as invisible, preventing them from appearing in Site Status Summary views and reducing operational noise for non-relevant or lab-only locations.
Updated legacy sensor and gateway records by marking old-company sites as IoTLab and adding new attributes for accurate historical tracking and data integrity.
Platform Infrastructure & Scalability
Created a nested CDK stack (device-dashboard-stack.ts) to overcome the AWS CDK 500-resource limit, unblocking continued dashboard and infrastructure growth without refactoring the entire main stack.
Advanced dashboard-related groundwork to ensure the Atria platform can scale safely as new device views and reports are added.
Application Features & Notifications
Implemented an email notification system in the Atria app, improving user awareness of system events and aligning app behavior with broader notification standards.
Documentation & Knowledge Management
Migrated GREF documentation from the deprecated Confluence space to the current board, restoring continuity after access revocation and ensuring documentation is centralized and discoverable.
Continued general documentation improvements to support maintainability, onboarding, and operational clarity.
Reporting, Coordination & Alignment
Produced a comprehensive technical report of GREF work completed by Milvian since project inception, creating a single reference point for stakeholders and leadership.
Held discussions with stakeholders to align on new Device & Site API definitions, ensuring a smooth transition away from legacy email bot workflows and reducing future integration risk.
Logistics & Operational Support
Completed logistics tasks including shipping survey kits back to the designated warehouse, ensuring inventory accountability and closing out field operations cleanly.
Notified relevant stakeholders regarding remediation actions, maintaining transparency and alignment across technical and product teams.
Cost Optimization & Engineering Improvements
Refactored the LoRaWAN Data Lake KMS configuration by enabling S3 Bucket Keys, reducing AWS KMS API usage and lowering ongoing infrastructure costs without impacting security.
Lowlights / Issues
Process & Access Challenges
Temporary loss of access to the legacy Confluence space delayed documentation migration and required coordination with multiple stakeholders to restore historical records.
Technical Constraints
Hitting the CDK resource limit highlighted structural scaling constraints in the existing stack architecture, reinforcing the need for continued modularization as the platform grows.
Overall
This week focused on stability, visibility, and scalability across the Atria and GREF platforms. Key notification and reporting improvements ensure administrators receive consistent operational insight, while infrastructure changes removed hard limits blocking future growth.
Documentation, reporting, and API alignment work strengthened organizational clarity and reduced long-term maintenance risk. Cost-optimization efforts delivered measurable cloud savings, and operational tasks closed several lingering logistical and remediation items.
Overall, the work meaningfully improved platform reliability, observability, and readiness for scale, while also paying down technical and organizational debt.
