Hi, I’m Sai Srinivas Gada. I am a Senior Software Engineer with 5 years of experience architecting high-performance fintech and healthcare solutions. I design scalable Microservices and Event-Driven Architectures that handle peak loads, including 5,000+ transactions per second with low latency.
Beyond coding, I lead cross-functional squads, advocate TDD and CI/CD, and enjoy turning legacy systems into scalable platforms. I leverage Cassandra and NoSQL for write-heavy workloads, and build observable, user-friendly dashboards with React. I love collaborating with product and security teams to deliver reliable, secure fintech solutions.
