Harun Mioc developed and enhanced both frontend and backend systems for Procure-Hub, focusing on procurement workflows, admin efficiency, and user experience. On the procure-hub-fe repository, he built a cohesive UI component suite with theming, a toggleable sidebar, and improved analytics visualizations using React, Material UI, and CSS-in-JS. Backend work in procure-hub-be included new procurement lifecycle controls, a buyer dashboard auctions endpoint, and a robust alerts subsystem, leveraging Node.js, Express.js, and Sequelize. Harun also implemented PDF contract reporting and improved admin reporting flows, demonstrating depth in API development, state management, and cross-team collaboration to deliver maintainable, business-driven features.

May 2025: Delivered four cross-cutting features across backend and frontend that drive procurement decision accuracy, admin efficiency, and audit readiness. Implemented a Buyer Dashboard Auctions Endpoint that aggregates auctions, computes statuses, and includes winning bid details to enable informed procurement decisions. Rolled out Admin Reports Popup in the UI to present disputes, suspicious activity, top buyers, and top users with robust loading and fallback states. Enhanced analytics visuals to support negative values in the HorizontalPercentageBarChart and wired in new API endpoints for BuyerAnalytics and SellerAnalytics. Enabled admin-driven contract activity reporting by introducing a PDF export flow with AdminContractLogsPopup, pdfContractService, and route-level data enrichments for improved user naming and contract details. These changes collectively improve decision support, governance, and data accessibility while maintaining alignment with security and performance requirements.

April 2025 monthly summary: Delivered end-to-end frontend and backend enhancements across Procure-Hub FE and BE, focusing on business value, UX consistency, and procurement lifecycle improvements. Frontend work established a cohesive UI component suite with Preview and Theming, added a toggleable Sidebar, and standardized styling across components (sidebar, toasts, pagination), while streamlining Admin User creation flow. Backend work introduced a new 'frozen' status and lifecycle for procurements with validation and controller integration, expanded the procurement alerts subsystem with generation, admin notifications, de-duplication, and route organization, and enabled admins to modify procurement statuses bypassing buyer limitations. Fixed accessibility-related UI color and contrast issues to improve readability. Overall impact: faster admin operations, more reliable procurement processes, and a cohesive, accessible user experience. Technologies/skills demonstrated: React frontend theming, routing and state management; backend data modeling and API routing; alert workflows; cross-team collaboration and code maintainability.
