What I'm looking for

I seek senior roles building production AI/ML-enabled web applications with collaborative teams, strong CI/CD, and cloud-native infrastructure.

I am a Senior AI and Full Stack Engineer with a strong engineering foundation and proven experience building scalable, intelligent web applications across diverse industries.

I specialize in AI/ML, Python, PHP, TypeScript, MERN, Flask, Django, FastAPI, and WordPress, delivering high-performance front-end experiences and secure, scalable back-end systems.

I have designed and deployed production systems on AWS using Docker and Kubernetes, built LLM-powered applications with LangChain and LlamaIndex, and implemented RAG pipelines with vector DBs like Pinecone, Weaviate, and Milvus.

I collaborate effectively with cross-functional teams to translate complex business requirements into reliable, production-ready solutions and enjoy creating interactive AI interfaces and robust CI/CD workflows.
