Project details

You will get clear, practical technical documentation for your API, SaaS product, AI tool, or developer project.

I can help turn messy notes, source code, existing README files, workflows, or product explanations into documentation that is easy to follow for developers, clients, and non-technical team members.

Depending on the package, I can create a README, setup guide, API documentation, user guide, workflow documentation, prompt logic explanation, or a complete docs package.

My background combines AI automation, TypeScript/React development, API integrations, and technical writing, so I understand both the code side and the user side of documentation.

About Kostiantyn

Kostiantyn Z.Status: Offline
AI Automation Developer | OpenAI, Claude, TypeScript, React
Prague, Czech Republic - 3:50 pm local time
I build AI-powered automations and internal tools that help teams process data, reduce manual work, and make faster decisions.

My main focus is API automation + AI processing: taking data from forms, CSV files, databases, or external APIs, sending it through OpenAI/Claude, and turning it into structured outputs such as rankings, summaries, classifications, reports, or workflow recommendations.

What I can build for you:
- AI workflow automations using OpenAI API, Claude API, TypeScript, and React
- Tools that classify, score, summarize, or rank data based on your business rules
- Internal dashboards for reviewing AI results and approving next actions
- API integrations between AI models and your existing tools
- MVP prototypes that turn your idea into a working product quickly
- Clear technical documentation, setup guides, prompt logic, workflow instructions, and content drafts for AI-powered tools

Recent work:
- Built API automation for an AI candidate-matching tool: collected structured data, processed it through OpenAI/Claude APIs, and matched candidates to role requirements
- Built frontend screens, components, animations, and Dynamic wallet login for Hollab, a TypeScript/Solidity governance platform
- Built multiple hackathon MVPs in 48-72 hours using AI-assisted development workflows

I’m comfortable working with both technical founders and non-technical teams. My background in logistics operations helps me understand real workflows, handoffs, bottlenecks, and human review steps.

Send me a short description of your process or product idea, and I’ll suggest the simplest first milestone.
