I help small brands and business owners build or improve Shopify stores that are clean, stable, and easy to manage after launch.
Most clients hire me for new store builds, custom Shopify sections, metafields and structured content, integrations, launch support, and technical fixes that need to be done properly without creating more problems later.
My approach is simple: clean execution, realistic scope, and no chaos. I focus on building and shipping properly, with clear communication, maintainable structure, responsive behavior, and a handoff the client can actually use.
I also take on selected WordPress and Elementor work when the scope is clear and implementation-focused. For internal workflows, I can support tightly scoped web apps and tools using Angular, .NET Web API, and SQL.
If you need a clean Shopify build, section updates, launch support, or practical technical help, send me your store URL, platform, and deadline. I’ll reply with a realistic scope, milestones, and the fastest sensible path forward.

🌟 Hi there! My name is Emil.
**Give me a workflow to automate, an AI agent to build, or a business process to put on autopilot — and I'll deliver it so it runs 24/7 without breaking. That's my promise.**
I'm a Top Rated automation developer with 10+ years of full-stack experience — which means I build N8N workflows, AI agents, and OpenClaw assistants that actually talk to real backend systems and databases, not just no-code toys that fall apart when traffic hits them.
⚙️ N8N Automation & Self-Hosting
- Self-hosted N8N on your own server — no per-execution fees, full data ownership
- Complex multi-branch workflows with proper error handling, retries, monitoring
- Migration from Zapier and Make to N8N (massive cost savings)
- Custom N8N nodes when standard ones aren't enough
🤖 AI Agents & LLM Integrations
- OpenAI (GPT-4, GPT-5), Claude (Anthropic), and open-source LLMs
- AI agents for support, content, research, lead qualification, data processing
- RAG pipelines, vector databases, embeddings, semantic search
- Custom AI tools that integrate directly with your existing systems
🦞 OpenClaw — Personal AI Assistants (Early Adopter)
- Self-hosted OpenClaw setup on your server, Mac, or Raspberry Pi
- Custom skills and plugins that connect to your business tools
- WhatsApp, Telegram, Discord, Slack, Signal, iMessage assistants
- OpenClaw + WordPress / WooCommerce / Hetzner / Gmail integrations
- Persistent memory, browser control, autonomous workflows
🔌 Real-System Integrations (my unfair advantage)
- WooCommerce, WordPress, Stripe, Shopify, HubSpot, Airtable, Notion, Google Workspace
- Custom REST APIs in Laravel / Node when off-the-shelf integrations aren't enough
- Direct database access (MySQL, PostgreSQL) from N8N or OpenClaw — most automation freelancers can't do this
- Webhook architecture, queue systems, background jobs
📊 Why clients hire me:
- 263 projects delivered | 5,930 hours billed | $200K+ earned on Upwork
- 100% Job Success Score | Top Rated
- 10+ years building production systems — not just demos
- I scope honestly, quote clearly, and don't disappear mid-project
🕜 Availability
Online 12 hours a day, 6 days a week. Fast replies, deadlines respected, clean code. I work independently and take ownership from day one.
If you send me a message or invitation, I'll reply with a short Loom video showing exactly how I would approach your project — no template, no fluff, just a plan.
Kind Regards,
Emil ⭐️⭐️⭐️⭐️⭐️
