👋 I build real systems, not “just automations”.

If something in your business depends on manual work, missing data, broken workflows, or scattered tools — I fix it. Properly.

I design and deploy production-grade automation systems, AI pipelines, and CRM integrations that remove bottlenecks and scale with your business.

What I Actually Do (Based on Real Projects I Build Daily)

✅ Advanced Workflow Engineering (Make.com, n8n, Zapier)

I build complex, multi-branch scenarios:

• Webhook → Data Normalization → Multi-system Sync

• File processing (PDF.co → OCR → GPT → Rename → Drive routing)

• Error-proof pipelines for high-volume operations

• Async job handling, token refresh, API rate-limits, retry logic

✅ AI-Powered Business Operations

I integrate GPT-4o, Claude, Perplexity and custom vector stores into:

• Document classification & enrichment

• Knowledge base sync (Google Drive → GPT)

• Automated summarization for email, files, Slack

• Multi-agent AI decision flows

• OCR → AI → CRM pipelines

✅ CRM & Lead Systems You Can Actually Trust

I’ve connected and stabilized:

• ActiveCampaign (complex tagging, funnels, conditional logic)

• HubSpot & Pipedrive (API-based sync + deduplication)

• Airtable automations & record-level logic

• WordPress/Elementor → Webhooks → Notion/CRM

• Indeed → Email parsing → Candidate pipelines

✅ Custom Solutions That Replace Manual Labour

I build systems that companies run their operations on:

• Applicant tracking automations

• Sales funnel logic

• Operational dashboards

• No-code internal tools

• Marketing workflows with 0 manual intervention

How This Translates Into Real Business Value

⚡ Less chaos

You stop relying on fragile workflows, missing data, broken zaps, and manual copy-paste.

⚡ More speed

Your team works inside clean, automated systems — not scattered tools.

⚡ More revenue

Your leads move faster, your emails convert, and your funnels stay consistent.

⚡ Scalable foundation

You get automations you can grow on, not a spaghetti of tools.

Tools I Use Daily (Not Just “Know”)

Make.com • n8n (self-hosted included) • Zapier • ActiveCampaign • HubSpot • Pipedrive • Klaviyo • Notion • Airtable • WordPress/Elementor • Google Cloud Vision • PDF.co • Telegram Bots • GPT-Agents • API integrations (OAuth, webhooks, REST, JSON mapping)

Why Work With Me?

• You won’t have to explain your tech stack twice. I’ve built with almost every major SaaS tool and API.

• I think like an engineer, not a “VA for automations”.

• I build systems that don’t break, with proper logging and error handling.

• I communicate clearly, document everything, and keep you updated.

• I care about reliability, not quick hacks.

If your workflows are slowing you down — I fix that.
