Saran Mayilsamy

I am a Backend Developer and Software Engineer with a strong track record of delivering scalable, secure, and data-driven solutions. I have collaborated directly with the Nokia team in a customer-facing environment, gathering requirements, designing solutions, and delivering features on time ensuring client satisfaction and building trust in high-stakes projects.

At Protecto, I have led multiple impactful initiatives, including building a Python library that automated metadata and policy retrieval from Snowflake and Redshift (reducing integration effort by 50%), implementing Google & Microsoft SSO with Keycloak in Streamlit (boosting user signups by 70%), and developing secure authentication/authorization services with OAuth 2.0. I also streamlined payment operations by integrating Stripe with FastAPI.

Beyond these, I have engineered practical solutions such as an online programming test portal for colleges and an OPD application that improved patient-doctor engagement. I thrive in environments where technology directly meets business needs, working with cross-functional teams to create solutions that are both technically robust and impactful.

Core Skills: Python (FastAPI), Streamlit, PostgreSQL, Kubernetes, OAuth2.0, SSO, Stripe, Google Analytics, Salesforce
