Futures Matching Engine & Risk Management Team
Architected and optimized high-throughput, low-latency components for the MEXC Real-time Risk Engine. Unlike Spot trading, the Futures engine requires continuous, real-time recalculation of margin requirements, liquidation thresholds, and Unrealized P&L (UPnL) for millions of active positions simultaneously.
Key Responsibilities & Technical Achievements:
Real-time Risk Validation: Developed a deterministic Risk Check module for pre-trade validation. Ensured every order meets margin requirements before entering the order book, maintaining a sub-10 microsecond latency floor.
Concurrency & Performance: Leveraged Rust’s memory safety to implement lock-free data structures (crossbeam). Allowed massive parallelization of balance lookups and risk calculations across thousands of concurrent users without traditional mutex contention.
Deterministic Execution: Optimized the engine for zero-garbage collection (Zero-GC) behavior, ensuring predictable P99 latency. Utilized custom memory allocators to eliminate jitter during high-volatility market events.
High-Performance Networking: Integrated the risk engine with the Matching Engine via high-performance IPC and shared memory segments. Successfully scaled the Risk Engine to handle 100k+ TPS during peak volatility.

Cryptocurrency Payment Gateway & Settlement Systems
Engineered a high-performance, multi-chain payment gateway facilitating real-time crypto-to-fiat and crypto-to-crypto settlements for high-volume digital asset marketplaces.
Key Responsibilities & Achievements:
High-Performance Architecture: Architected the core payment processing engine using Rust for mission-critical nodes. Leveraged Rust's safety guarantees to handle sensitive transaction logic, achieving 99.99% system uptime and zero critical memory-related failures.
Multi-Chain Integration: Developed robust interfaces for Ethereum (EVM), BSC, and Solana. Implemented smart contract interaction logic and real-time transaction monitoring to automate deposit/payout lifecycles.
Infrastructure Modernization: Led the transition to a unified gRPC microservices ecosystem. Established a centralized contract repository using Buf.build, reducing new service integration time by 40%.
Scalable Backend Development: Designed the peripheral service layer (user registration, payouts, reporting) using Go. Developed an automated Telegram-based operations bot for real-time status alerts and administrative controls.

Fintech & Payment Gateway Department
Engineered a high-performance payment gateway architecture processing millions of daily transactions, supporting a massive ecosystem of merchants and consumers.
Key Responsibilities & Achievements:
High-Load Dynamic Routing Engine (Rust): Designed the core payment routing module capable of processing complex configurations (6000+ line JSON schemas) "on the fly." Enabled real-time switching between acquirers based on fees and availability, optimizing cost-efficiency.
Microservices Integration Layer (Go): Developed high-concurrency banking clients as standalone microservices. Built robust wrappers for external banking APIs connected via strictly-typed gRPC contracts.
Scalable System Architecture: Delegated performance-critical paths to Rust for safety/speed, while utilizing Go for rapid scaling of business-logic-heavy service layers.
Platform Engineering: Engineered internal boilerplate tooling that standardized service creation, significantly reducing Time-to-Market (TTM) for new services.

Enterprise Service Management Team
Spearheaded the backend development and migration of a mission-critical internal ticketing system, replacing a legacy Jira Service Desk instance with a bespoke, high-performance Go solution.
Key Responsibilities & Achievements:
Ticketing Lifecycle & Media Engine: Engineered the complete ticket lifecycle backend in Go. Developed a specialized media processing service for handling diverse attachment formats and generating high-quality thumbnails.
Observability & Reliability: Instrumented the backend with Prometheus metrics and custom logging. Designed Grafana dashboards and Kibana visualizations to track system health and API performance 24/7.
DevOps & QA: Managed end-to-end deployment within the bank’s secure infrastructure. Collaborated with QA to implement automated integration testing.
Business Impact: The optimization of the ticketing engine resulted in a 40% reduction in average claim processing time for high-priority inquiries.
