FinTechAlgoExchange & Fintech Engineering

Enterprise-gradeexchange & fintech engineering

We design, build and operate high-load trading systems: FIX gateways, OMS/EMS, risk engines, professional scalping terminals and low-latency services. Backed by experience on systems processing billion+ monthly turnover.

What we build

Full-cycle engineering for trading and fintech: from architecture and PoC to production rollout and operations. We join existing teams or lead greenfield builds.

FIX gateways & connectors

FIX 4.2/4.4/5.0, FAST/ITCH/OUCH. Connectivity, routing, throttling, drop-copy, monitoring, certification tooling.

OMS/EMS & trading terminals

Order management, depth, tape, clusters, derivatives, hotkeys. Web & desktop, WebSockets/gRPC real-time UI.

Risk, limits & compliance

Real-time limits, margin, pre-trade checks, exposure & P&L, reporting, KYC/AML integrations.

Low latency / HFT components

Optimized network, batching, CPU pinning, GC tuning, precise time sync, deterministic retries.

Core backend services

.NET / C#, C++/Rust modules, event-driven architecture, HA, failover.

DevOps & observability

Kubernetes, GitOps, IaC, metrics/logs/traces, SLO/SLA, safe deploys, incident response.

Why teams work with us

FIX-native mindset

Session management, recoverability, gap handling, idempotency, deterministic routing and robust logging are baseline, not extras.

Security & NDA-first approach

Work under NDA, detailed audit trails, least-privilege access, encryption in transit & at rest, structured documentation for technical and compliance due diligence.

Selected case studies

High-level descriptions only. Details available under NDA.

High-frequency scalping terminal & risk suite (NDA)

  • Multi-screen terminal: large DOM ladders, prints, clusters, order flow analytics.
  • Designed for billion+ monthly notional and dense tick data.
  • Real-time risk console: per-trader/global limits, auto cut-offs.

BitMart API education & starter toolkit

  • Public educational materials & sample code for BitMart REST/WebSocket API integration.
  • Showcased auth, order flows and market data streaming for algo traders.
  • Confirms hands-on exchange API integration experience.
ARB ENGINE

FIX / FAST arbitrage engine

  • Low-latency connectors for FIX & FAST feeds with resilient session handling.
  • Multi-venue monitoring, mispricing detection, strategy routing.
  • Built-in risk checks; initial deployment on local markets, architecture portable globally.
