Platform Engineering & Developer Productivity: Conceptualized and implemented a reusable
Function-as-a-Service (FaaS) library. Delivered complete HLD/LLD documentation, which simplified microservice
deployments and reduced boilerplate code for multiple development teams.
Performance Optimization at Scale: Re-architected the storage backend by replacing PostgreSQL with AWS
S3. This strategic pivot removed connection bottlenecks, enabled horizontal pod scaling, and halved data read
times, significantly boosting throughput.
Data Pipeline Architecture: Engineered Proof of Concepts (POCs) for high-volume Snowflake-to-S3 data
transfers using Python/PySpark and Native Snowflake Pipes. Provided comparative analysis to stakeholders to
select the optimal production rollout strategy.Location: Bangalore, India
