Design and build ultra-low latency, high-throughput backend services and off-chain infrastructure for real-time trading on Solana. Optimize engine latency and throughput, lead greenfield system design, implement monitoring and observability, collaborate with quants and smart contract engineers, and mentor junior engineers to uphold high engineering standards.

Design and implement high-throughput on-chain exchange logic and smart contracts in Rust for Solana. Build AMMs, funding-rate mechanisms, margin and liquidation systems, and real-time risk management. Translate research and economic models into performant SVM programs and optimize protocol execution for Solana runtime constraints.

Lead and manage SRE/DevOps teams to improve reliability, incident response, scalability, and security of a cloud-native infrastructure. Develop reliability roadmaps, collaborate cross-functionally on cloud strategies, and implement proactive measures to minimize downtime and optimize performance.

Lead the migration of a validated web prototype into a high-performance React Native app, own client rebuild, deployment pipelines (App Store, Play, Steam), backend architecture, offline-first sync, subscription integration, CI/CD setup, and ensure cross-platform UI/UX and data privacy compliance for kids (COPPA/GDPR-K).

Design, optimize and maintain the exchange's low-latency matching and risk engines. Build and scale trading gateway connectivity, improve throughput/latency, support REST/WebSocket client integrations, debug complex issues, write thorough unit and integration tests, and collaborate with Quant, Gateway, and Product teams to enhance blockchain signature SDKs.

Develop and optimize ultra-low-latency algorithmic trading systems for cryptocurrency markets using C++/Rust. Collaborate with quants and traders to implement strategies, troubleshoot and maintain high-performance execution engines, and stay current with HFT and crypto developments.

Develop and train foundation models for robotics, align text-based reasoning with low-level control policies, design and run zero-shot generalization experiments, collaborate with interdisciplinary teams, and present research findings at conferences.

Lead ecosystem and partnership strategy to drive integrations, DeFi onboarding, RWA issuer engagement, and institutional adoption. Own partner lifecycle, negotiate strategic deals, coordinate cross-functional integrations, and translate partner feedback into product and go-to-market improvements while representing the platform externally.

Design and implement multi-agent orchestration frameworks, build tool-calling pipelines and reasoning loops, and optimize latency and token usage for real-time agentic workflows.

Lead and scale an institutional-grade DeFi ecosystem: design and execute ecosystem roadmap, secure strategic partnerships and liquidity, drive marketing and community to increase TVL and user acquisition, and build/manage high-performing remote and local teams across marketing, business development, and operations.
