PROFILE
Mai Yer Lee
Over eleven months, Michael Lee engineered robust budgeting, reporting, and access control features for the HHS/OPRE-OPS repository. He delivered end-to-end workflows for procurement change requests, role management, and authentication, emphasizing data integrity and security. Using Python, React, and SQLAlchemy, Michael refactored APIs to improve schema clarity, implemented granular permission models, and automated CI/CD deployments. His work included integrating OpenAPI documentation, enhancing test coverage with Cypress and Pytest, and streamlining data migration and validation processes. By focusing on backend reliability and frontend consistency, Michael enabled faster, safer releases and improved the accuracy and auditability of financial and contract data.

Sep 1, 2025September 2025 monthly summary for HHS/OPRE-OPS focused on strengthening access control, auditing, and deployment governance. Delivered a new Role Management System to import and update roles from spreadsheets with database migrations for role events, data transformation, unit tests, and logging of role creation/updating with associated permissions to ensure accurate access control and auditable changes. Configured Environment Admin Role across Production and Staging to enable proper admin access controls via TEMPORARY_YEAR_END and SUPER_USER settings in production and a staging SUPER_USER variable. Fixed a bug by removing a duplicate POST_RESEARCH_PROJECT permission in user data configuration to improve consistency and correctness of permission management. Result: improved security, compliance, and operational reliability through auditable changes and consistent permission definitions.

Aug 1, 2025August 2025 monthly summary for HHS/OPRE-OPS. Delivered three core features: in-review workflow enhancement to include agreement change requests; budget line item project details schema integration with SimpleProjectSchema and OpenAPI; and budget line item fee calculation enhancements supporting locked-in and agreement-specific fees, plus no-fee cases. Each feature included tests and refactors to improve correctness. These changes improve governance of changes, improve data availability for downstream systems, and standardize fee calculations across budget line items. Overall business impact: faster, more reliable change governance, richer project data in budgets, and more accurate fee billing. Demonstrated skills: schema design, refactoring, test-driven development, and OpenAPI integration.

Jul 1, 2025July 2025 highlights for HHS/OPRE-OPS focused on strengthening change governance, improving data accuracy, and tightening frontend/backend quality. Delivered the Procurement Shop Change Request Workflow, adding an end-to-end approval process for procurement shop changes on agreements, including new schemas, services, migrations, and auditing to support creation, review, and application of changes. This feature was driven by commits fd6037ab4a369a1a5af05ea885d8854785bd2aeb. Implemented the Budget Line Item Fees Field, exposing a new fees field in budget line item responses; updated API docs, schemas, TypeScript types, and tests (commit f08a188fb355983dbe6b76521f5b14f53cd48f6a). Restored Agreement Edit Permissions, fixing a regression and strengthening tests to ensure basic users can’t edit agreements they are not associated with (commit fe63deda73f21c2f74be711999cc751fa831d908). Fixed null handling when constructing change summaries by ensuring procurement shop is set before changes are built, preventing incorrect reporting (commit 4ee1bac31422fc4e432f39c8b917b1dd8a5189a9). Kept code quality improvements by removing a stray console.log from AgreementDetailsView (commit 24d25de044b1f5c37d3aeaedd1a6abf5675abfee). These changes collectively reduce risk in procurement workflows, improve reporting accuracy, and enable richer data for decision making, while enhancing test coverage and API fidelity.

Apr 1, 2025April 2025 monthly summary for HHS/OPRE-OPS: Key features delivered to improve budgeting visibility and CAN handling, expanded permissions, and stronger test stability. Major accomplishments include CANs enhancements (sorting active CANs by appropriation year; including BLIs with no date_needed; displaying 'TBD' when total funding is zero), master BLI data loading with improved status calculations and alias mappings, and expanded permissions for agreements and service components. The testing suite was stabilized with data alignment improvements, race-condition fixes for CanCard rendering, and CI reliability improvements. These efforts collectively improve data quality, reduce manual reconciliation, and enable faster, safer collaboration across portfolios. Technologies and skills demonstrated include front-end feature work, data loading and ETL-like updates, permission modeling, and Cypress-based test automation.
