Dear Hiring Manager, I am interested in the Data and Evidence position. I design and deliver production-grade data science solutions using traditional machine learning alongside modern GenAI and emerging agentic technologies, including using multi-agent systems and MCP to help automating data science tasks: from data cleaning, analysis, modellling and visualization. [3] [4] Beyond standard RAG, I have hands-on experience fine-tuning models like Gemma 3 to meet specific domain requirements. By utilizing Unsloth and LoRA, I’ve streamlined the fine-tuning process to be viable on single-GPU setups without sacrificing model quality. I bridge the gap between training and production by deploying these models via vLLM on AWS, ensuring the final solution is both scalable and cost-effective. My work spans end-to-end data science web apps across time series, geospatial data, images, video, and text, translating complex, real-world data into actionable insights. My online CV with project links is available here: _Website not available. Sign in: https://www.twine.net/signup_ For GenAI agentic applications, I build systems where agents dynamically select prompts, tools, and models based on task context. In multi-agent solutions, each agent has clear role separation (e.g., analyst, coordinator), with robust tool orchestration, memory management, and structured reasoning pipelines such as ReAct-style workflows to ensure reliable and interpretable behaviour as they scale. I am an AWS Certified AI Practitioner [1] as well as Cloud Practitioner [2] with deep understanding of modern neural network architectures, including Transformers, LSTMs, and CNNs, besides classical statistical/ machine learning models.
