Project description
Contributing to the development of an ERP / business management platform focused on sales, warehouse, logistics, treasury, purchasing, catalog, analytics, and point-of-sale operations, with a web (SPA) client, a cross-platform Electron POS client, and a .NET backend monorepo with APIs, Azure Functions, integrations, and configurable tabular data components and history.
Key features
Large-scale enterprise frontend: broad business domains (orders, warehouse, shipping, invoicing, purchasing, analytics, HR, settings), complex tables and forms, reporting and charts (ECharts, Nivo, ApexCharts, among others)
Web client with React, Vite, React Router, Redux Toolkit / Zustand / TanStack Query, Zod validation, MUI and Radix, dnd-kit, and very dense data UIs (virtualized tables, spreadsheet-style views)
Electron POS for Windows, macOS, and Linux: electron-builder packaging, auto-updates, custom protocol for deep links, typed IPC, and thermal printing for retail
Rich .NET 8 backend: ASP.NET Core with OpenAPI, EF Core, Azure Functions (HTTP, Service Bus, timers, Durable Functions), Redis, Azure integrations, and private artifact pipelines
Cross-layer integration: versioned API client against the Leberp API, decoupled flows with queues and bulk jobs, Application Insights across web, POS, and cloud components
Product quality: ESLint, Prettier, Vitest, Testing Library, Playwright, Storybook, and bundle analysis on the frontend side
Challenges and solutions
Functional complexity and consistency
Keeping UX and data consistency across very different modules (sales, warehouse, treasury, POS) and between web and desktop channels, with evolving rules and a huge screen surface.
Performance for dense UIs
Large grids and heavy lists need virtualization, well-scoped TanStack Query usage, and careful bundle strategy in a very large codebase.
