I specialize in designing and deploying LLM-powered applications, AI agents, and end-to-end intelligent systems that solve real business problems. From idea to production, I focus on building solutions that are fast, scalable, and reliable. Over the years, I’ve worked extensively with AI agents and voice systems using tools like CrewAI, AutoGen, Amazon Polly, Deepgram, and Rasa. I have strong experience in fine-tuning large language models using techniques like LoRA, QLoRA, RLHF, and DPO with frameworks such as Hugging Face, Unsloth, and Axolotl. I’ve also worked with a wide range of open-source LLMs, including LLaMA 3, Mistral, Mixtral, Falcon, and Gemma, and I optimize their performance using tools like vLLM, TGI, and TensorRT-LLM.

On the frontend, I build modern, high-performance interfaces using React, Next.js, Vue, and TypeScript, creating seamless user experiences across web and mobile platforms. In addition, I work with tools like OpenAI APIs, Whisper, and various ML libraries including NumPy, Pandas, and Scikit-learn. I also have experience with automation, testing, and rapid prototyping using low-code AI tools like Flowise and LangFlow. What sets me apart is my ability to combine deep AI expertise with full-stack development, allowing me to deliver complete, production-ready solutions—not just prototypes.
