Purvesh Patil
As a Specialist Programmer at Infosys, I build end‑to‑end web platforms that combine modern full‑stack development with applied AI/ML to solve real business problems at scale. My recent work includes integrating automated penetration testing and security checks directly into development workflows, and developing intelligent resume‑parsing and candidate‑ranking systems that make hiring faster and more data‑driven. I work primarily with Node.js, Express, MongoDB, React, and Python, and enjoy designing clean APIs, resilient architectures, and CI/CD pipelines that keep releases fast and reliable. On the AI side, I experiment with NLP models, embeddings, and RAG workflows to add features like smart search, chatbot assistants, and automated document understanding into existing products. Security, performance, and developer experience are core to how I approach engineering. I like diving deep into debugging, profiling, and threat modeling, and I’m always looking for ways to automate repetitive tasks so teams can focus on building new capabilities. Outside of project work, I explore new tools in DevOps and generative AI, contribute to internal knowledge sharing, and mentor peers on writing maintainable code and thinking with a security‑first mindset. I am always open to connecting with engineers, security enthusiasts, and product teams interested in building reliable, intelligent systems.
