Autonomous FinTech Analytics

Architecting a real-time financial data pipeline with sub-second latency using ClickHouse and Python.

The Outcome

Query latency reduced by 94% (from 500ms to 30ms). System now handles 50k events/second with zero downtime.

01 / The Challenge

Technical Bottlenecks

The client, a high-frequency trading firm, faced 500ms+ latency in their existing SQL-based analytics, causing missed arbitrage opportunities. Data fragmentation across 4 legacy ERPs made real-time reconciliation impossible.

02 / Systems Architecture

The Solution Design

High-level System Design

We replaced the relational core with a columnar ClickHouse cluster, ingesting event streams via Apache Kafka. A Python-based aggregation layer was built to normalize data in-flight.

03 / Execution

Engineering Rigor

  • Implemented automated CI/CD pipelines ensuring 99.9% uptime.
  • Comprehensive unit and integration testing coverage using standard libraries.
  • Full documentation of API endpoints and system dependencies.
