What I'm looking for

I seek roles building production-grade LLM and generative AI systems with strong MLOps practices, collaborative remote teams, and opportunities to scale secure, high-performance AI products.

I am a results-driven AI Engineer and Backend Developer with hands-on experience designing, building, and deploying production-grade machine learning models, LLM-powered applications, and agentic AI workflows. I have engineered RAG pipelines, integrated Hugging Face and LangChain solutions, and delivered secure, high-performance APIs deployed via Docker and CI/CD on cloud platforms.

I have led projects ranging from AI chatbots and fraud/compliance document ingestion systems to an OMR exam marking system and MQTT-based IoT pipelines, demonstrating strong MLOps/LLMOps practices and cross-team collaboration. I excel at turning complex business challenges into scalable AI products and continuously improving model delivery and monitoring in production.
