Senior Software Developer FinTech & AI Solutions

Greeshma Guduguntla Software Developer

Conroe, TX 716-***-**** *******************@*****.*** LinkedIn Github SUMMARY

Software Developer with almost 5 years of experience in designing and delivering robust FinTech and AI-enabled software solutions across enterprise environments. My expertise encompasses Java, Spring Boot, Python, JavaScript, and TypeScript

(including React and Angular), and I have a proven track record of building scalable, high-performance systems in the banking and regulatory domains. I combine strong back-end skills (SQL, PL/SQL, JDBC) with front-end development and integration of machine learning models (TensorFlow, PyTorch) to create intelligent applications that drive business impact. I am adept at deploying microservices in cloud and containerized environments (Docker, Kubernetes), automating full-lifecycle delivery via CI/CD (Jenkins, GitHub Actions) into the software lifecycle. Known for mentoring cross-functional teams, performing performance tuning, and reducing defect rates, I strive to deliver maintainable, future-ready code that aligns with business goals.
