Jan 2023 – Nov 2024 · 1 yr 10 mos

Migrated a monolithic application to a microservices architecture across comments, chat, user, and media domains, enabling independent deployment, improving scalability and fault isolation while optimizing system maintainability and resilience.
Worked on Kong API Gateway to implement routing logic for microservices and integrated plugins for authentication and authorization.
Designed a real‐time chat architecture using Apache Kafka for high‐throughput message streaming and integrated EMQX broker with MQTT to handle clients in low‐bandwidth or unreliable network conditions, ensuring persistent queues, low‐latency delivery, and supporting 50k–100k messages per second.
Implemented real‐time spam and profanity prevention in chat using Apache Kafka with rule‐based and model‐based blocking, collaborating with the data team to track offending users and enforce policies.
Built a high‐performance real‐time animation engine for live classes using uWebSockets and Apache Kafka, optimizing event pipelines for minimal latency and high throughput, enabling interactive animations to engage users during live sessions.
Adhered to Test Driven Development principles using Jest, maintaining 90% unit test coverage across all deliverables.
