Financial Data Platforms

Data is the lifeblood of modern finance, but most generic data platforms fail when faced with the velocity of market data or the strict audit requirements of regulators. We build specialized data infrastructure for high-throughput ingestion and millisecond-latency analytics — operated in production at both startup and institutional scale.

High-Frequency Ingestion & Storage

Ingesting millions of market data ticks per second requires more than a large database. We build hybrid architectures that balance extreme performance with long-term storage costs:

• Time-Series Excellence: Implementation of kdb+, ClickHouse, or TimescaleDB for sub-millisecond query performance on massive datasets.
• Event-Driven Pipelines: Leveraging Kafka, Aeron, or Chronicle Queue to ensure data remains consistent across distributed systems with exactly-once semantics.
• Tiered Storage: Optimizing the balance between high-cost NVMe for hot data and low-cost object storage for historical archives — automated by policy, not manual migration.

Real-Time Stream Processing

Latency in financial data isn’t measured in seconds — it’s measured in microseconds. We design streaming pipelines that move market data from exchange to decision engine with minimal jitter:

• Streaming Ingestion: Building on Aeron, Kafka, or Chronicle Queue for deterministic, low-latency message delivery with kernel-bypass where microseconds matter.
• Stateful Stream Processing: Using Apache Beam, Dataflow, or Flink for real-time aggregations — VWAP calculations, P&L tracking, risk limits — without batching delays.
• Data Lake Integration: Streaming enriched market data into Iceberg or Delta Lake tables for downstream research, while maintaining exactly-once semantics and point-in-time accuracy.

ML Platform Engineering

We built a global machine learning platform on GCP for a tier-one bank’s financial crime detection organization — standardizing on TensorFlow, TFX, Kubeflow Pipelines, and GKE. Results included 25% faster model training cycles and 20% infrastructure cost reduction through drift elimination. We bring the same rigour to your ML infrastructure:

• Feature Engineering at Scale: Building feature stores with Dataflow and BigQuery that serve both training and inference consistently.
• Model Deployment & Monitoring: Production-grade ML pipelines with model drift detection, A/B evaluation frameworks, and automated retraining triggers.
• GPU/TPU Optimization: Right-sizing accelerator utilization to balance training throughput against infrastructure cost.

Regulatory Data Compliance

In regulated markets, you must prove not just what you know, but how you know it. Our platforms satisfy MiFID II, SOC 2, and FCA requirements through:

• Immutable Audit Logs: Tamper-proof storage with cryptographic verification of your transaction history.
• Data Lineage Tracking: Mapping the flow of data from source to reporting, enabling complete transparency during regulatory inspections or investor due diligence.
• GDPR & Data Residency: Implementing localized data storage and encryption patterns for global operations spanning the UK, EU, and APAC jurisdictions.

Proven Impact

• Realtime Risk Analytics: Cut VaR and stress-report generation from 3 hours to 14 minutes with Apache Beam and Dataflow, while keeping legacy quant libraries in play.
• Finance Crime ML Platform: Delivered a global ML platform on GCP detecting financial crime across regions, improving model training by 25% and reducing infra spend by 20%.
