• Reduced ad overspend from 10–15% to below 1% by replacing scheduled batch jobs with a Kafka Streams pipeline processing 1 billion ad events per day. Cut processing latency from ~30 minutes to near-real-time.
• Led an ad-fraud detection and automated-refund initiative across 6 teams, combining a data-science model with legacy detection. Reduced false positives and recovered 0.5% of daily ad consumption previously lost to incorrect fraud detection.
• Re-platformed the stats subsystem from a single-source pipeline to a composable multi-source aggregation model, enabling batch and real-time systems to contribute to the same statistics. Reduced event-processing latency, added backpressure handling for peak load, and enabled automatic fallback to alternate data sources during upstream outages.
• Led and delivered a GitOps migration for ~50 workflows on an internal orchestration platform used by 6 teams. Replaced manual UI-based upgrades with reviewable merge-request changes and added self-service scheduling, local development, and end-to-end testing.
• Created TypeKube, a Deno/TypeScript toolkit adopted across ~10 internal teams to generate Kubernetes manifests, alerts, and dashboards from type-safe definitions. Standardized deployment and observability configuration across hundreds of services and repositories; local validation and compile-time checks cut new-service setup from hours to minutes.
• Designed and built BigQuery-backed ads reporting and analytics systems, owning architecture from ingestion pipelines to query optimization. Built an end-to-end test framework using the BigQuery emulator for local pipeline testing.
• Drove performance, infrastructure, and cost optimizations across Ads: halved request volume in a Store Ads integration, removed unused services and database indexes, and used a DSL-based design to avoid doubling recommendation-engine traffic.
• Led incident response, recovery, and post-mortems for database, Kafka, and seller-facing migration incidents. Improved pipeline error delivery to surface previously silent failures and drove preventive fixes across service boundaries.
• Mentored ~10 engineers, served on 5+ promotion committees, and led cross-team design reviews and technical planning. Helped establish dedicated technical-backlog capacity and team-health measurement.
• Extended CodiMD into a documentation platform adopted across multiple teams. Built a separate frontend and a tag-based virtual-folder hierarchy for document categorization and discovery; integrated the platform with AI workflows through MCP and custom tooling.

• Built and maintained Node.js microservices for a healthcare platform on AWS using Lambda, DynamoDB, and Cognito; contributed to a Haskell backend and React applications in a distributed team.
• Built an end-to-end design-to-application pipeline: a TypeScript Figma plugin used heuristics to interpret manually crafted, 30–40-page app journey designs and generate structured JSON; a Haskell validation and repair tool checked and corrected the output. Replaced weeks of manual design translation with automated generation, reducing turnaround from 2–3 weeks to 2–3 days.
• Brought design and mobile/frontend engineering teams together to establish a shared design language, enabling direct code/JSON generation from designs and further shortening delivery times.

• Developed Java microservices for the CMS used to manage AppGallery applications; designed API endpoints and owned the development and maintenance of the CI/CD pipeline.
• Served as technical lead for a newly formed team of ~10 Cordova developers adapting Huawei Mobile Services for third-party frameworks; designed projects, coordinated work allocation, conducted reviews, and guided delivery. Built cross-framework libraries with the React Native team and automated workflows using Bash.

• Built a course-commerce platform using Node.js, Express.js, MongoDB, React, and Next.js; deployed on GCP.
