Wasif Nadeem

I’m a Senior Software Engineer with 10+ years of experience delivering enterprise B2B SaaS, eCommerce, healthcare IT, and AI-driven solutions across frontend, backend, cloud, and DevOps. I build responsive, scalable, high-performance applications using JavaScript (ES6+), TypeScript, Python, C++ and .NET/C#, with strong product sense and a consistent focus on security and maintainability.

At Tech Rover (Jul 2023–Present), I architected and delivered full-stack healthcare, e-commerce, and fintech systems with HIPAA-compliant data handling and scalability. I built secure backend APIs and microservices using ASP.NET Core and Node.js, integrated PostgreSQL/Cosmos DB/MongoDB, added Redis caching and RabbitMQ for message-driven reliability, and implemented authentication workflows with Azure B2C, Passport, JWT, and M2M token strategies. I also enhanced automation with N8N workflows and AI/ML + OpenAI with RAG, designed GraphQL endpoints to optimize data fetching, containerized services with Docker, orchestrated deployments with Kubernetes and Nginx, and improved code quality by raising test coverage to 85%.

Previously at Microsoft (Jan 2020–Jun 2023) and Airbnb (Feb 2014–Dec 2019), I delivered enterprise-scale web and cross-platform solutions and built high-traffic eCommerce and B2B SaaS platforms using React/Angular/Node.js/.NET/Python. I reduced UI development time by 30% through reusable component libraries and design systems, strengthened ETL pipelines for real-time analytics, improved DevOps reliability by reducing deployment failures by 25%, and accelerated delivery timelines by 25% through aligned technical roadmaps. Across teams, I’m known for mentoring engineers through architecture reviews and TDD, partnering with stakeholders, and consistently driving measurable business outcomes.
