Freelancer Overview

Senior full-stack developer with 10 years of experience building production web applications in TypeScript, JavaScript, React, Next.js, and Node.js. Most recently architected an AI-powered rich-text editor at Neurohive AI, integrating multiple LLMs (OpenAI, Anthropic Claude, Perplexity) with streaming responses, tool calling, and LangChain-based document processing. Daily hands-on experience designing prompts, evaluating model outputs, and building agentic workflows using Claude Code, GitHub Copilot, SDD, and the Vercel AI SDK in my own projects (textual.chat, habitrack.io, emailcompat.dev). Strong fit for code-focused labeling tasks: writing and reviewing prompt-response pairs for SFT, function/tool calling evaluation, and code quality assessment across TypeScript, JavaScript, Python, SQL, HTML/CSS, and React. Comfortable with structured rubrics, edge-case reasoning, and detailed written feedback — skills sharpened through years of code review, technical interviewing, and architectural decision-making. Bachelor of Software Engineering, National University of Kyiv-Mohyla Academy (2017).
