Karan Saini
Software Engineer & Problem Solver.
I’m a software engineer who builds products that solve real problems. I focus on backend engineering and scalable systems, and I enjoy turning user needs into clean, impactful solutions.
I believe great software blends technical excellence with product thinking—whether it’s performance, reliability, or user experience, I build what matters.
Experience
Selected roles focused on backend systems, platform engineering, and real-time data infrastructure.

Quant Associate (Software Engineer II)
Algo One AI
- Architected and delivered a provider-agnostic Trading API with a Python SDK, unifying multiple broker and market-data vendors behind one interface; standardized models/events; reduced integration effort by ~60% (~250 dev-hours/integration); adopted by 5+ internal systems.
- Built a high-throughput real-time streaming pipeline processing ~20k events/s using Kafka for fault-tolerant transport and Cassandra for scalable time-series storage.
- Led development of a high-throughput distributed trading platform processing 5k+ msg/s; architected a microservices-based real-time OMS, multi-broker connectivity layer, and risk engine for production-grade execution.
- Built a low-latency, multimodal voice-first conversational AI "digital nurse" (EN/HI) with safety-first triage guardrails and clinician-ready handoff outputs, including automated one-page PDF report.
