ПРОФЕСІЙНИЙ ПРОФІЛЬ
AIAutomation & WorkflowSpecialist ізпрактичним project-based досвідом створення AI-powered
workflows, n8n automations, API-connected content systems та структурованих production pipelines.
Основний фокус - no-code/low-code automation, HTTP Request workflows, webhooks, polling, retry logic, file
handling, Google Drive/Docs workflows, Telegram bot automations та workflow debugging.
Створив і покращив 50+ n8n workflows, включно зі складними multi-service pipelines на 120+ nodes та
до 6 підключених сервісів в одному workflow. Маю 1+ рік практичного досвіду з n8n automation та
приблизно 2роки щоденної роботи з AI tools і prompt systems.

PROJECT-BASED EXPERIENCE
AIAutomation&WorkflowSpecialist - Project-Based
Вересень2025 - Present | Remote
- Створював, редагував, тестував і покращував 50+ n8n workflows для AI content production, media workflows,
file-based triggers, Telegram bot automations, website form intake та multi-step production pipelines.
- Створював складні n8n workflows на 120+ nodes та до 6 підключених сервісів, використовуючи HTTP Request nodes,
webhooks, polling, retries, API authentication, JSON payloads та structured file handling.
- Створював AI-powered production workflows, які автоматизують значну частину процесу від title/input data до scripts,
voiceover, subtitles, AI avatar video, background music, rendering та організованого збереження в Google Drive.
- Працював з Anthropic/Claude, Google Drive/Docs workflows, ElevenLabs, Whisper via Replicate, HeyGen, Comfy, 69Labs,
Shotstack, Telegram bots та AI image/video generation tools.
- Створював Google Drive project structures з окремими folders/files для images, videos, subtitles/SRT, scripts, voiceover,
final outputs та intermediate workflow state.
- Працював з binary files у n8n, включно з mp3, mp4, images, docs, XLS files та subtitles.
- Debugged workflow issues, пов’язані з authentication errors, invalid API responses, missing files, broken URLs, wrong
binary keys, empty fields, invalid JSON, timeouts, infinite polling loops, memory issues та non-valid AI/service outputs.
- Покращував стабільність workflows через block-by-block testing, intermediate file saving, retry logic, polling limits,
fail-safe checks, Throw Error nodes та structured debugging workflows.
