I’m Vinay, a Senior Python Developer with 11+ years of experience building web and enterprise applications using Python and Django. I thrive on designing scalable APIs, optimizing high-traffic systems, and delivering data-driven solutions across cloud platforms (AWS, GCP) and modern DevOps stacks (Docker, Kubernetes, CI/CD). I also work with ML/NLP tools, vector search, and LLM integrations to empower research, product, and business teams.
Collaborative by nature, I enjoy partnering with cross-functional teams to translate complex requirements into reliable software, robust data pipelines, and reusable components. I’m passionate about continuous learning and applying the latest AI/ML advancements to real-world problems.
