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.
