Architect high-throughput, scalable, and fault-tolerant distributed systems.

Evaluate FIX messaging, exchange API integrations, and order and execution recovery mechanisms.

Identify root causes of production incidents, performance bottlenecks, and system failures.

Define and implement high-availability, disaster recovery, and business-continuity solutions.

Assess cloud infrastructure, security controls, monitoring, and deployment practices.

Develop practical architecture recommendations and prioritized remediation roadmaps.

Support modernization of legacy applications while preserving critical business functionality.

Provide hands-on technical leadership, including solution design, troubleshooting, and implementation of critical components.

Collaborate with senior management, business stakeholders, and engineering teams to align technology solutions with business and operational requirements.

Improve engineering standards, development processes, and production support capabilities.
