Transforming High-Frequency FinTech Architecture
A radical re-engineering of order routing latency, ergonomic trader density, and institutional workflow mechanics for Aura Capital's global multi-asset desk.
A complete modernization of Aura Capital's multi-asset trading desk, replacing a fragmented legacy terminal with a sub-18ms WebAssembly execution core, zero-modal ergonomic design, and unified design token architecture.

Project Overview
Re-Engineering Ultra-Low Latency Architecture for High-Frequency Quantitative Trading
Codytics designed and developed Aura Pro Terminal, an ultra-low latency multi-asset trading platform for Aura Capital Inc., delivering a comprehensive high-frequency trading solution across institutional workstations, curved ultrawides, and mobile companions.
The platform streams real-time market data ticks, order-book depth matrices, and liquidity telemetry using a deterministic WebAssembly execution core: WebSocket multiplexing, lock-free SharedArrayBuffer memory caching, sub-18ms tick-to-trade dispatch, and zero-modal contextual drawers.
Codytics delivered the full platform in 16 weeks (Q1–Q2), covering systems architecture, Rust/Wasm engineering, UI/UX design, token system unification, and distributed cloud infrastructure.
Terminal latency and visual fragmentation remain two of the biggest contributors to trader fatigue and execution slippage. Quantitative desks handle $4.2B in weekly multi-currency turnover, yet traders routinely grapple with thread freezes during economic announcements, fragmented multi-window modals, and inconsistent visual hierarchy. While off-the-shelf trading terminals exist, they introduce severe challenges of their own:
Aura Pro Terminal was created to address these architectural gaps through a performance-first approach. Codytics designed the platform to optimize the entire trading lifecycle from tick ingestion to order execution with speed, cognitive clarity, and operational discipline.
The product had strong vision, but the software was slowing the business down.
Diagnosing critical latency choke points, trader cognitive fatigue, and fragmented monolithic pipelines across legacy infrastructure.
Core ArchitectureLatency & Fragmentation
Sub-optimal data synchronization across disconnected market data pipelines resulted in out-of-order execution packets and up to 68ms peak lag.
User WorkflowCognitive Fatigue
Dense unstructured UI grids with inconsistent visual hierarchy caused decision lag and mis-clicks during volatile market announcements.
System PerformanceMonolithic Thread Choking
Single-threaded state managers choked under simultaneous tick volume bursts, freezing DOM layout recalculations by up to 42 fps.
The Solution
How Codytics solved these problems.
How micro-frontends communicate across zero-copy shared memory to process hundreds of thousands of market events per second without dropping frames.
Solution 01•Shared MemoryZero-Copy SharedArrayBuffer Pipeline
Web Workers ingest streaming binary WebSocket frames directly into SharedArrayBuffers, bypassing main-thread garbage collection pauses.
Engineered for Aura Capital Inc.: high-concurrency throughput with resilient real-time failover.
Eliminated operational bottlenecks and established scalable foundations for future growth.
Solution 02•Rust / WasmCompiled Rust/Wasm Calculation Core
Order-book depth aggregation and weighted spread calculations compiled to high-speed WebAssembly for sub-microsecond algorithmic crunching.
