I’m looking to build secure, high-performance full-stack AI platforms end to end integrating LLMs/RAG, conversational agents, and scalable cloud architectures, with ownership across frontend, backend, and deployment to ship measurable business impact. I’m a Senior Full-Stack AI Engineer with 7+ years building enterprise SaaS platforms, AI-powered applications, and scalable cloud solutions for startups and global clients. I design end-to-end systems with Python, Django/FastAPI, React, PostgreSQL, Docker, and AWS, with a strong focus on LLM integrations, Retrieval-Augmented Generation (RAG), conversational AI, and API-driven architectures. In my most recent role, I led end-to-end development of AI communication features across frontend, backend, and cloud infrastructure—building multilingual voice/chat/sms experiences, integrating conversational AI and workflow automation, and delivering secure, high-performance services. Previously, I built scalable APIs and microservices (FastAPI/Flask/Django), engineered multilingual AI voice agents, and supported data platforms—while also shipping full-stack SaaS products with measurable improvements in testing success, deployment speed, and customer retention.
