About Tanmay Mathur

I build production-grade analytics platforms that replace legacy BI tools with modern, interactive full stack applications.In my current role, I led the migration of 2 enterprise Tableau dashboards to React + FastAPI applications deployed on AWS — delivering 50+ interactive chart modules, Kaplan-Meier survival analysis, custom Sankey visualizations, and real-time filtered dashboards serving cross-functional stakeholders in the pharmaceutical industry.What I bring to the table:→ Full Stack Development: React 19, FastAPI, SQLAlchemy, Python, REST APIs→ Cloud & DevOps: AWS (ECS Fargate, CloudFront, ElastiCache, CloudFormation), Docker, CI/CD→ Data Engineering: Redshift, PostgreSQL, advanced SQL, ETL pipelines, Pandas→ Enterprise Security: SSO (ForgeRock OIDC/PKCE), JWT authentication, OWASP compliance, RBAC→ Data Visualization: Recharts, custom SVG charts, Kaplan-Meier curves, Sankey diagrams, cohort funnels→ Analytics: Real-World Data (RWD), Tableau, treatment pattern analysis, competitive intelligenceI\'ve designed end-to-end cloud infrastructure using CloudFormation (1,400+ line IaC templates), built Redis caching layers for sub-second query responses, developed a deterministic NLP chatbot with 71+ intent handlers, and automated 3-environment CI/CD pipelines with Docker + CodeBuild + ECS.Previously, I built automation workflows and Tableau dashboards at Axtria for pharmaceutical decision science engagements, and supported production AWS infrastructure at Cognizant.AWS Certified Developer – AssociateOpen to opportunities in: Analytics Engineering, Full Stack Development, Data Engineering, BI Modernization, Cloud-Native Application Development.Let\'s connect → t••••••••@gmail.com
