Led project planning, deliverable breakdowns, and milestone setting for an international client base. Oversaw sprint planning, ticket grooming, daily scrums, backlog management, and client communication to ensure alignment with business goals and successfully meet the needs of diverse, worldwide customers.Guided junior project managers, focusing on skill development in project management principles and methodologies, contributing to team growth and project success.Key project and achievement: AWS cost savingScope and descriptionManaged a company-scale AWS cost reduction initiative to drive cost-saving measures across multiple areas.1) Reduced infrastructure cost: Conducted in-depth analysis of databases (docDB, Elasticache, RDS, Kafka, OpenSearch), storage (S3, EBS), compute (EC2), and network (VPC, CloudFront). Achieved cost efficiency through strategies such as optimizing database instances, implementing data retention policies, removing unused data, using Karpenter for node management, and disabling unused logs.2) Revisited service design to identify opportunities for product optimization. Actions included deprecating unused services, transitioning away from OpenSearch, finding optimal resource allocations (CPU, memory), and utilizing the Garbage Collector for Java services, etc.TeamCollaborated with cross-functional teams: Infra/Hosting team, Release and Operational team, Product Engineering team, Performance Engineering team, Finance team. ImpactImproved production environment margins from -36% to +11% within six months.

Established a structured release management process from the ground up, ensuring smooth deployments across production and staging environments, improving release efficiency, and reducing downtime. Developed and delivered tailored services to meet unique client requirements. Be the primary communicator between internal teams and client’s stakeholders.Key project and achievement: Own the Product Release process and environment lifecycleScope and descriptionEstablished a structured release management process from the ground up, ensuring smooth deployments across developments, staging, and production environments, improving release efficiency, and reducing downtime.1) Defined the development process, including branching models, CI/CD flow, quality assurance, and delivery.2) Owned day-to-day product release operations and continuously improved and automated the release process.3) Owned the environment lifecycle (spin up, modify, and teardown environments based on the customer needs)TeamLed a team of 5-20+ members, including junior project managers, DevOps engineers, and QA engineers; collaborated closely with Product Engineering leads, Product Managers, and customer producers.ImpactEstablished a robust release process, transforming a previously unreliable production environment that never functioned end-to-end. This enabled dozens of engineering teams to release high-quality services without disrupting other functionalities. Expanded from one production environment to hundreds, ensuring all environments are consistently up-to-date.

Responsible for delivering the project. Led and managed the project team, with authority and responsibility from the project board, to run day-to-day project operations. Served as Scrum Master, overseeing project planning and progress monitoring, developing schedules, estimating timelines, managing issues, and providing regular progress reports

Developed a production system (Enterprise Resource Planning) by working with Business Analysts to turn user requirements into system designs, assigning tasks to programmers, and leading developers to meet project requirements accurately.

Developed an ETL-based middleware to connect legacy and new systems (ERP systems), ensuring seamless data integration and transition.
