Senior Software Engineer

Engineered usage-based billing workflows using Java, Apache Kafka, and Apache Flink for high-volume event ingestion, asynchronous processing, accurate usage metering, and reliable billing outcomes. Built event-processing flows that separated incoming events from downstream billing operations and applied distributed-systems patterns to backend services.

Developed real-time subscription analytics with Apache Flink, Java, SQL, and Python for revenue, churn, and trial-conversion metrics. Improved payment monitoring and production reliability through Python automation, SQL, anomaly detection, data validation, API design, and observability practices.

Investigated application and database latency for cloud-migration readiness using Java, SQL, Python, and performance-testing scripts. Traced request flows and bottlenecks across service boundaries to inform backend optimization and improve cloud-connected service reliability.

Improved event-platform and product-data services with Apache Kafka, Spring Boot, Redis, schema validation, distributed tracing, and Python automation. Also contributed to database self-service workflows using Terraform, Kubernetes, and CI/CD to streamline provisioning and standardize platform operations.

Contributed to a Java-based microservices architecture powering the Amazon Search page, supporting scalable backend services and REST API integrations. Worked with search infrastructure, featured-merchant ranking, personalization widgets, and offer indexing for the Amazon Fresh search launch in Singapore.

Designed backend business logic and API integrations for a marketplace Prime refinement. Helped customers distinguish international and local offers through reliable service integrations and marketplace search functionality.

Extended the Amazon Search Page stack with Java and service APIs to support marketplace launches in Australia, the UAE, Singapore, and Poland. Integrated search-page services with marketplace-specific product and offer data for Amazon Global Store experiences.

Designed an AWS Lambda and Java automation framework that reduced marketplace stand-up time by up to six months. Built personalized React and JavaScript search widgets, a regional Python and SQL data pipeline with sub-30 ms reported latency, and an A/B experimentation framework for personalized search-result widgets.

Helped design and develop an extensible, data-driven content-conditioning pipeline for a collaborative game engine supporting multi-core architectures and virtual reality. Worked on a multithreaded pipeline designed to scale from a developer workstation to a clustered server environment.

Contributed to multi-user workflows for editing scenes from different machines and viewing results across multiple devices. Integrated stream-based reactive APIs and RESTful APIs for cloud systems.

Developed client- and server-side features and bug fixes for a cross-platform mobile MMORPG using C++ and PostgreSQL. Implemented one-on-one player-versus-player dueling and player-stat tracking across matches.

Expanded internal development tools used by artists, designers, and QA to create in-game content. Extended the crafting system to provide players with additional reward options.
