Transforming a legacy financial reporting codebase into a sub-second distributed analytics platform processing $2.4B+ daily volume.
The Challenge
FinTrack came to WebVishno with a critical dilemma: their legacy 12-year-old monolithic application was crashing during market opening spikes, batch jobs required 4 hours, and enterprise hedge funds were demanding real-time sub-second telemetry.
Our Engineered Solution
WebVishno architected a decoupled event-driven streaming system using Go, Redis streams, ClickHouse column-oriented database, and Next.js 14 reactive dashboards with WebSocket pipelines.
Architectural & Sprint Approach
Conducted a 4-week architectural discovery audit, established zero-downtime database replication, built microservices incrementally using strangler patterns, and deployed high-availability clusters on AWS with automated failover.
“WebVishno re-engineered our core engine without a single minute of downtime for our 8,000 daily traders. The performance leap is extraordinary.”

Measured Results & Impact
Reduced analytical query latency from 42 seconds to 18 milliseconds, supported $2.4B+ daily transactions with 99.99% uptime SLA, and saved the client over $420,000 annually in server and maintenance costs.
