About Sahana Yadav

I’m a Full Stack Developer with 3+ years of experience building enterprise-grade software across healthcare, supply chain, and e-commerce. I thrive at the intersection of backend engineering, cloud infrastructure, and AI/ML innovation — delivering solutions that are scalable, secure, and impactful.At McKesson, I designed patient self-service portals in React.js and Redux that onboarded new digital users in six months and reduced call-center volume by 2,500+ cases each month. I engineered Spring Boot microservices that validate over 1M+ monthly healthcare eligibility checks, automated Python ETL pipelines with LLM-powered data normalization to process 100K+ records weekly, and built ML-driven APIs that eliminated 40K+ duplicate prescription errors annually across 12 distribution centers.Previously at Dell Technologies, I improved supply chain operations by ingesting 500K+ daily ERP records through AWS Lambda pipelines, reducing API turnaround times from 9s to under 3s, and enabling finance teams to run 1,200+ concurrent reports with sub-2s latency. I also developed React.js dashboards for daily transactions and delivered ML forecasting models generating 45K+ weekly demand predictions, saving 300+ analyst hours annually.I take pride in solving complex problems, collaborating across teams, and driving measurable results — whether that means scaling an edtech platform to handle 50K+ daily events, cutting reporting latency in half, or accelerating release cycles with automated pipelines.Looking ahead, my goal is to continue building systems that blend full-stack engineering with AI-driven intelligence, helping organizations unlock efficiency, reliability, and innovation at scale.Let’s connect if you’re looking for someone who can deliver enterprise-ready solutions, optimize workflows, and bring fresh problem-solving energy to your team.
