# Mansoor Siddiqui > Senior Software Engineer with full-stack expertise in React, Angular, and Django Location: Brooklyn, New York, United States Profile: https://flows.cv/mansoor As a full-stack engineer at Genentech, I leveraged my expertise in React, Next.js, Django, and GraphQL to revamp and maintain an internal tool that aids in scientific discovery and analysis. I take ownership of high-value features, from systems architectural design to full implementation and testing. Previously, I collaborated on multiple teams at Apple, where I converted the frontend codebase to the latest version of Angular, rectified code regressions, vulnerabilities, and stale design patterns, and built out new features to meet business objectives and customer requests. I also worked with key stakeholders across product, design, QA, and build out full-stack features across micro-services. Additionally, I built an internal tool at Vercel to help prioritize workflow for the engineering team, sourcing data from Github issues and other customer feedback pipelines into an interactive user interface. I hold a Bachelor of Science degree from Drexel University. ## Work Experience ### Software Engineer @ Genentech Jan 2023 – Present Led the revamp and ongoing development of a critical internal platform supporting scientific discovery and data analysis Owned high-value full-stack features, driving improvements in both frontend and backend architecture.
