What I'm looking for

I’m looking for a role where I can build production-grade full-stack products and apply modern AI responsibly—especially RAG, fine-tuning, and analytics that drive clear decisions. I’m open to remote work and relocation.

I’m a results-driven Full-Stack Developer, AI Engineer, and Data Analyst focused on delivering intelligent applications across the full software development lifecycle. I design scalable web systems and build AI capabilities such as Retrieval-Augmented Generation (RAG) pipelines, leveraging LangChain, FAISS, and LLM APIs to improve answer quality.

In my AI Developer internship, I reduced hallucination rates by over 30% on domain-specific Q&A tasks and fine-tuned open-source LLMs using LoRA adapters. I also ship production-ready services by building FastAPI microservices with structured logging and secure endpoints, then translate business requirements into AI-powered product features. Currently, I analyze insurance claims using Python and Excel, automate weekly reporting (from 4 hours to under 30 minutes), and support reserving and pricing decisions with regression, survival analysis, and time-series forecasting.
