Designed scalable and robust application architectures for enterprise solutions, aligning with business objectives and long-term technology strategy. Collaborated closely with Enterprise Architects to ensure solutions adhere to overall technology standards, principles, and roadmap. Owned end-to-end solution delivery, from initial concept and design through development, integration, testing, deployment, and support. Acted as DevOps Lead, driving automation, CI/CD pipeline implementation, and fostering a culture of continuous improvement across development and operations teams. Partnered extensively with Infrastructure teams to ensure seamless integration and optimal performance, scalability, security, and reliability of applications on cloud and on-premises platforms. Contributed to technology tendering processes (RFx), including solution definition, technical requirement specification, vendor evaluation, and selection to secure best-fit technology partners. Partnered with the ISC (Information Security & Compliance) department to proactively ensure systems met stringent security and compliance requirements. This included incorporating static code analysis (SAST), managing penetration testing engagements, and ensuring adherence to specific regulations like China Multi-Level Protection Scheme (MLPS / 等保) into the development and deployment lifecycle.

As a Senior Technology Architect Manager at Accenture, I led the design and delivery of large-scale digital transformation initiatives for Fortune 500 clients across Life Sciences, Industrial, and Telecommunications sectors. My expertise centered on architecting secure, compliant, and scalable cloud-native solutions to drive operational efficiency, business growth, and enhanced user experiences. Key Responsibilities & Value Delivered: • Strategic Architecture: Owned end-to-end solution and technical architecture design for critical client projects, ensuring alignment with business goals, compliance (e.g., HCP communication), and future scalability. • Cloud-Native Platform Leadership: Architected and delivered modern platforms using cloud-native principles (Microservices, Containers, Kubernetes) on Azure, AWS, and hybrid environments. • Full-Stack Delivery: Directed implementation of integrated solutions utilizing WeCom/WeChat Mini Apps/Vue for UX, and backend technologies including Kubernetes, Docker, Kong, Istio, Spring, and Keycloak. • Business Enablement: Enabled growth through digital ecosystems - replacing legacy systems (e.g., consolidating 24 platforms into a unified service portal), building compliant communication channels (e.g., HCP engagement via WeCom), and re-engineering core systems like supply chain forecasting for precision (daily-level accuracy). • Complex Project Execution: Managed the full lifecycle of technical projects, collaborating with global clients and vendors to ensure successful outcomes.

At Meituan Waimai (China’s largest food delivery platform handling billions of annual orders), I architect and deliver mission-critical Java solutions for the Material Management and Marketing Budget Allocation systems. As a P6 Technical Expert, I lead high-performance engineering initiatives impacting 30M+ daily active users, prioritizing millisecond response times, data integrity at scale, and robust system resilience without cloud dependencies. Core Technical Focus： • Distributed Java Architecture: Designed end-to-end solutions leveraging Java 8 (lambda/streams), Spring 4.x (Core, MVC, Security), and Apache Tomcat 8, optimized for high concurrency. • Performance-Centric Databases: Architected MySQL 5.6 sharding solutions using Vitess-inspired patterns; implemented connection pooling via HikariCP and query optimization. • In-Memory Data Grids: Engineered Terracotta Ehcache and Hazelcast clusters to manage 150K+ TPS for real-time budget tracking and inventory state. • Asynchronous Processing: Integrated RabbitMQ for asynchronous job queues handling 100M+ daily funding reconciliations, ensuring eventual consistency. • API & Inter-Service Communication: Developed high-throughput RESTful APIs and RPC services using Thrift, enabling <5ms inter-service calls. • DevOps Rigor: Automated deployments via Jenkins with Ansible, and monitored systems using Nagios + ELK stack. Key Achievements: ✔️ Led redesign of budget distribution engine, handling peak loads of 12,000 requests/sec with 99.99% uptime using Java NIO and thread pool optimization. ✔️ Reduced material allocation API latency from 450ms to 58ms through JVM tuning (GC algorithms, heap profiling), caching layers, and lock-free algorithms. ✔️ Secured financial transactions with idempotency patterns and reconciler jobs, preventing double-spending risks on $100M+ monthly promotional
