I am a Backend Software Engineer with 3+ years of experience designing and scaling distributed systems and high-throughput APIs. Experienced in optimizing database execution plans, eliminating lock contention under concurrent workloads, and building fault-tolerant event-driven pipelines using Kafka and Airflow. Strong production ownership through on-call debugging, performance profiling, and reliability improvements.   



Core strengths: Python, Java, C++, PostgreSQL, Kafka, AWS, and scalable microservice architectures.

   

Completed MS in Computer Science with focus on distributed systems and advanced algorithms.

## Work Experience
### Software Engineer @ UHS
Jan 2025 – Present | California, United States
Designed and scaled Python (Django/FastAPI) backend services handling high-volume healthcare transactions, reducing P99 latency by 45% via async I/O, connection pooling, and query plan optimization.
Architected stateless, horizontally scalable microservices with idempotent REST APIs, sustaining 99.9% uptime across distributed deployments.
Increased transactional throughput by 40% by redesigning composite indexing strategies, eliminating lock contention, and tuning execution plans under concurrent workloads.
Implemented fault-tolerant event-driven pipelines (Kafka + Airflow) processing streaming data into Snowflake with retry semantics and failure recovery.
Led on-call production investigations, diagnosing memory bottlenecks and race conditions using profiling, structured logging, and performance tracing.

### Software Engineer Intern @ University of California Office of the President
Jan 2024 – Jan 2024 | Oakland, CA
Led end-to-end data migration to AWS using AWS DMS and Amazon Aurora (MySQL/MariaDB), scaling data volume from 300K 
to 500K+ records while ensuring data lifecycle management, governance compliance, and schema consistency. 
Designed and implemented automated ETL pipelines to streamline data transfer and integration between GCP and AWS environments, 
ensuring high performance, data quality, and scalability within Amazon RDS architecture. 
Developed and secured data analytics dashboards for a pension management platform using Google API Management, aligning with 
strict data privacy regulations, security protocols, and system compliance standards. 
Built and deployed full-stack web applications and RESTful APIs using React (JavaScript/TypeScript), Flask, and FastAPI, 
significantly enhancing system responsiveness, usability, and cross-platform functionality. 
Collaborated within Agile Scrum teams using Jira to manage sprints and deliverables, achieving 90%+ backend test coverage with 
JUnit, Jasmine, and Mocha to ensure system reliability, maintainability, and rapid iteration.

### Full Stack Engineer @ Cybage Software
