What I'm looking for

I want to build and ship production-grade full-stack products powered by LLMs, RAG, and intelligent automation—on remote-friendly teams—where I can own system design, accelerate release cycles, and apply MLOps for reliable deployments.

I’m a Full-Stack Engineer with 6+ years of experience delivering production-grade software systems for international clients, starting in full-stack web development and progressively specializing in Generative AI, Large Language Models (LLMs), and Retrieval-Augmented Generation (RAG). I build end-to-end AI-powered products with measurable business impact, combining LLM engineering with robust system design and real-world deployment practices.

I’ve led the architecture and deployment of AI platforms and agents—like an AI Recruiter Platform that reduced HR screening time by 95%, and an AI Voice Agent that eliminated missed after-hours calls—by integrating Python, LangChain, OpenAI/ChatGPT APIs, vector databases, and MLOps observability. I also ship modern microservices and full-stack applications using FastAPI/Django/Node.js, React/Vue, and CI/CD pipelines on cloud infrastructure (AWS/GCP) to accelerate release cycles and ensure reliability across concurrent projects.
