Backend Software Engineer at Xoxoday who improved API response times by ~40% at MyBliss.

India

Message

At Xoxoday, I developed Node.js REST APIs for digital rewards and marketplace workflows, integrated backend services across product domains, and resolved production reliability issues.

At MyBliss, I improved API response times by ~40% through caching and query optimization. I also reduced database query latency from ~200ms to ~60ms by indexing and refactoring MongoDB and MySQL queries.

I built AWS Lambda-based image optimization workflows that reduced image load times by 50%, and migrated video processing to AWS Elemental MediaConvert to generate adaptive HLS streams. I also developed monitoring and alerting workflows that achieved 99.9% service uptime.

Earlier, I worked on React platform improvements, customized ExoPlayer for HLS streaming, and developed Android live-streaming applications using FFmpeg and Linux pipelines.
