Условия

• Trading interfaces process up to 100,000 orders per day over real-time streams, running inside an Electron host
• Some work reaches into compiler territory: formula engines, expression parsing, AST generation, incremental recalculation
• Across all of it, the data shown must be correct, and the system must stay usable when data volume spikes 10x to 100x during a market event
• when the browser becomes a distributed system node +
• Financial UIs are not presentation layers
• They consume real-time streams, maintain local state that must stay consistent with backend state, and handle the same class of distributed failure problems as any backend service: messages that arrive late, twice, or out of order
• Every consumer must be idempotent
• A duplicated message in a UI table can mean a duplicated trade or an incorrect position
• Frontend correctness is financial correctness
• The practical consequence: WebSocket sessions disconnect and must reconnect cleanly. Subscriptions drop and must re-subscribe without losing or duplicating state. When a real-time stream fails, the UI falls back to HTTP and re-requests data. These are not edge cases
• they are expected operating conditions in a trading environment
• react internals, not just React APIs +
• A financial UI under load, during a market event that drives data volume 10x to 100x above normal, exposes problems that React API knowledge alone cannot diagnose: scheduling delays in the fiber reconciler, rendering bottlenecks under concurrent updates, memory pressure from large dataset virtualization
• Understanding how React schedules work at the fiber level, how the browser rendering pipeline interacts with JavaScript execution, and where to find the bottleneck in Chrome DevTools is what separates a UI that degrades gracefully from one that freezes
• complex frontend engineering tasks in high‑integrity systems +
• In advanced financial and enterprise environments, frontend engineering evolves into the construction of programmable, stateful, compiler‑like systems that operate inside the browser. The UI is no longer a passive presentation layer
• This is not component assembly or UI decoration
• It is the engineering of a programmable, resilient, stateful system that users rely on for correctness, performance, and continuous adaptation to complex operational demands
• what we use as technology stack +
• React 19 with Strict TypeScript and React Strict Mode
• MUI, AG‑Grid, JSS, and our internal UI Kit
• Electron host application with WebView and custom protocol handlers
• Mini‑frontends communicating inside Electron
• Code generation for HTTP clients and backend models
• Vitest, Playwright, and Copilot‑generated E2E tests
