Designing and implementing automated pipelines for integrating LLMs into user workflows. Working with large language models via OpenAI, Claude, Gemini, Perplexity APIs. Using OpenRouter for multi-model routing and cost/performance optimization. Fine-tuning inference parameters (Top-P, Top-K, Temperature, Reasoning Effort) for task-specific behaviour. Creating prompts from scratch and refactoring existing user and developer prompts. Applying prompt design patterns (persona, audience, template, recipe, visualisation generator). Using advanced prompting techniques: zero-shot, few-shot, chain-of-thought, self-consistency, tree of thoughts, directional stimulus prompting, reflection. Writing prompts for multiple domains and use cases with different constraints and objectives. Testing and benchmarking prompts using built-in and custom evaluators. Designing Retrieval-Augmented Generation (RAG) pipelines. Working with vector databases for semantic search and contextual retrieval. Optimising chunking, embedding strategies, and retrieval parameters. Developing a marketing AI agent that retrieves LinkedIn user data via API and generates personalised, targeted advertising content. Building an internal MVP consisting of multiple agents for:
- prompt generation and improvement
- input/output analysis
- basic automated testing of LLM outputs
Creating a personal assistant for:
- monitoring and notifying about relevant job openings based on user profile
- providing on-demand market data (stocks, currencies)
Deploying AI services in Google Cloud. Containerising applications and managing environments with dependencies. Automating workflows and integrations using n8n.

Дополнительная информация

General information

Junior specialist in artificial intelligence with a focus on data science and computer vision. I have 1 year of commercial experience in developing and implementing machine learning models, including working with images and data in practice. I am well versed in modern frameworks: TensorFlow, Hugging Face, Open API, basic level - PyTorch. I understand the architecture of transformers, attention mechanics (Query / Key / Value), token operation, as well as the principles of Retrieval-Augmented Generation (RAG) and model evaluation. I am actively developing in the direction of LLM and NLP, studying vector databases, and have applied experience with cloud platform infrastructure (AWS, Azure, GCP - at the deployment and testing level). Previously, I had 2 years of experience as a Junior Back-End / DevOps Engineer: I am familiar with CI/CD, automation, containers, and backend infrastructure support. I work systematically: I am able to understand new tools, set priorities competently, and prefer structured documentation and clear communication. I strive for clean, reproducible, and understandable code.
