FAQ

FinTech & Market Data FAQ

Can you work with OPRA and US options market data?

Yes. We have built production pipelines that ingest a vendor's OPRA options feed and dark pool trades, classify trade sentiment, aggregate in 60-second windows across parallel jobs and stream results to live dashboards.

How do you handle traffic bursts at market open?

Bounded in-memory queues, a connection pool per stream, pipelined batch writes of thousands of messages, burst detection on 200 ms buckets and alerts on any dropped message. Stalled feeds restart automatically within minutes.

Do you build trading execution systems?

Our core strength is analytics, market data infrastructure and AI tooling for traders. For execution-adjacent work we scope compliance and broker integration requirements together with your team before committing.
