Denys H.

AI & Workflow Automation Engineer | Google Apps Script, APIs, LLMs

I automate the work your team does by hand. 15 years in software, 100+ business tools built and running. From 2020 to 2026 I led business systems and automation at a US telecom construction company, building and maintaining the internal tools that finance, operations, warehouse, HR and safety teams relied on daily. Before that, I spent 9 years as a software engineer (Android, Java, back-end), working with clients on Upwork since 2014. What I can build for you: • Google Workspace automation - Apps Script, Add-ons, Sheets, Docs, Forms, Gmail, Drive, Chat: trackers, dashboards, approvals, notifications • AI workflows and agents (Claude, OpenAI, Gemini) - reading documents and extracting data, chat assistants that answer from your own files, AI steps with human review • Document generation - any document your business produces (proposals, contracts, invoices, reports, checklists), created automatically as PDF, Word or Google Docs from any data source you use (spreadsheets, forms, CRM, databases, emails) • Integrations & data - connecting your tools via APIs (QuickBooks, CRMs, payroll and accounting systems), importing CSV and Excel reports, reconciling data • Rescue work - taking over broken scripts and spreadsheets nobody understands anymore How I work: I start from your process, not the tool. I'll tell you when a simple formula beats a script, or when a tool you already pay for can do the job before you buy another subscription. Everything I ship has error handling, failure alerts and documentation, so your team isn't dependent on me. Tell me which process eats most of your team's time - I'll reply with how I'd automate it.
