Mechanical engineering, Donetsk National Technical University (2001-2006)About me
Remote web developer and Python automation freelancer based in Serbia. I turn approved content and file workflows into clear websites, repeatable checks and usable reports. Engineering/documentation background; AI-assisted development with agreed checks and handoff.

I build clear, responsive websites and practical Python tools for file-based workflows. My background is engineering and project documentation. I have worked on freelance projects part-time since 2017, with approximately four years of hands-on practice in Python, React and TypeScript.
Websites: business and property websites, landing pages, responsive layouts, content structure, forms and agreed content updates. Technologies include HTML, CSS, JavaScript, React, TypeScript and Tailwind CSS. I check desktop/mobile layouts, links, agreed user journeys and build outputs, and provide source files and an update guide.
Python automation: repeatable CSV validation, duplicate and missing-value checks, exception reports, scoped Excel processing and PDF report-packet assembly with bookmarks and source manifests. Technical documentation: registers, revision tracking, missing-file checks and source-to-output traceability.
Selected examples: Dun4ev Studio and Property Web Studio demonstrate website structure and responsive presentation. CSV Review and PDF Packet are independent examples using synthetic data. Document Intake is a workflow prototype; its OCR/AI extraction is not connected or production-tested.

I use AI-assisted development and verify the agreed outputs. Before work starts, we agree on inputs, access, scope, acceptance criteria, costs, revision limits and delivery dates. Paid hosting, licenses and third-party services need prior agreement. Maintenance is available for separately agreed recurring tasks. Remote delivery from Serbia; written communication preferred.

Project history
Selected self-initiated projects demonstrated publicly in October 2026:
Dun4ev Studio: responsive personal studio website, EN/SR presentation, clear service structure, project sections and contact paths.
CSV Review: Python validation of an agreed CSV schema, duplicate and missing-value checks, accepted/review separation and exception reports. Independent demonstration using synthetic data.
PDF Packet: ordered report and appendix assembly, page labels, bookmarks and a source/output manifest. Independent demonstration using synthetic files.
My work combines implementation, agreed checks and documentation. I use AI-assisted development and verify the resulting outputs. These are portfolio projects, not claims of paid client delivery.
