I'm a Backend and Data Engineer with 4+ years of experience designing and building scalable APIs, data pipelines, and analytics systems. 

I've developed backend systems that powered analytics dashboards, designed high-cardinality pipelines in Snowflake, optimized query performance and reduced infrastructure costs while ensuring data reliability across complex production systems.
 
I've built low-latency, event-driven microservices in Go and Kotlin on AWS, and implemented ETL pipelines to efficiently process large-scale data.
 
I’m passionate about designing efficient, reliable systems, tackling challenging data problems, and creating impactful products
