Presize AI

50% of fashion products are returned. 75% of them are due to the wrong size and bad fit. Fashion eCommerce shops lose money daily, and online shoppers are annoyed by returns.

Presize allows web shoppers to turn around in front of their smartphone camera once with normal clothes and automatically get their best-fitting clothing size recommended.

PySpark Data Pipeline

An ETL pipeline used to aggregate the user conversion numbers from the daily usage data of the application.
The pipeline had three major parts: data extraction from ElasticSearch in the form of CSV files, Logstash was used to fetch the daily data into CSV, and it was stored in S3 buckets.

The second part was performing aggregations on hundreds of GBs of data to extract the numbers for the finance team.
The third and final part of the pipeline was pushing the aggregated numbers to ElasticSearch to show them in Kibana dashboards.

I completed this project from inception to completion while designing the infrastructure architecture, which included the scalable deployment of ElasticSearch on Kubernetes clusters while ensuring the system's security and scalability.

Auction Application Scaling and Replication

I configured and managed multiple Beanstalk environments to handle increased traffic and demand. I implemented auto-scaling policies to ensure optimal utilization of resources and cost-effectiveness.

I implemented multi-region deployment strategies to ensure high availability and disaster recovery capabilities. I configured and maintained failover mechanisms to switch to a secondary region in case of a failure.

I established database replication strategies to ensure high availability and minimal downtime during maintenance and upgrades. I also monitored and troubleshot database replication issues and made necessary adjustments to improve reliability.

I integrated Datadog with the infrastructure to monitor and track the key performance metrics of the system and analyzed the container metrics. I identified performance bottlenecks.

I then collaborated with the development team to resolve technical challenges and improve the system's performance. I regularly monitored and analyzed the system's performance and made adjustments to ensure optimal operation.

I tested and validated the disaster recovery plan to ensure its effectiveness. Finally, I analyzed and evaluated the existing infrastructure for potential risks and failures.
