I find bugs before your users do — and I automate the
processes that slow your team down.
─── QA & Testing ───
Manual and automated testing for web and SaaS applications.
I write clear, reproducible bug reports that developers
actually understand: steps to reproduce, expected vs actual
behavior, screenshots, console logs.
→ Cross-browser testing (Chrome, Firefox, Safari, Edge)
→ Mobile testing on real devices
→ API testing with Postman — isolate frontend from backend
→ E2E automation with Playwright (JavaScript)
→ Test documentation: test cases, regression checklists
─── Workflow Automation (n8n) ───
I connect the tools your team already uses and eliminate
manual work permanently.
→ AI chatbot (GPT-4o-mini) on Telegram: answers FAQs,
captures leads, syncs to HubSpot automatically
→ CRM sync: webhook → HubSpot upsert with deduplication
→ Lead capture: form → Google Sheets → instant notification
─── Why clients come back ───
8+ years in operations and logistics means I understand
business processes — not just code. I build things that
work in production, handle edge cases, and document
everything so you're never dependent on me.
