Sahithi Gangasani

I’m a Full Stack Software Engineer with 5 years of experience designing and building cloud-native distributed systems using Java, Spring Boot, React, and Angular across fintech and healthcare platforms. I enjoy turning complex requirements into reliable, customer-facing features and maintainable services.

In my current role at Charles Schwab, I designed and delivered customer-facing and internal financial features using microservices architecture, supporting 50,000+ daily active users with 99.9% uptime. I built scalable REST APIs (aligned to OpenAPI specs), integrated them with React, and improved performance by reducing average page load time by 28%.

I’ve also led improvements around event-driven architecture, observability, and testing. I integrated Kafka-based event-driven communication to improve scalability and reduce processing latency, implemented centralized monitoring with OpenTelemetry, Prometheus, Grafana, and AWS CloudWatch to cut troubleshooting time by 42%, and strengthened quality with JUnit/Mockito—raising code coverage to 86% and reducing production defects by 31%.

Recently, I’ve been integrating generative AI and LLM-powered capabilities into production systems using AWS Bedrock, LangChain, and RAG architectures. I’ve built production-ready document intelligence and agent-based tutoring/quiz experiences, including secure, GDPR-aligned handling, containerized deployments, and measurable retrieval/summarization gains—backed by AWS and Oracle Java certifications.
