About this gig
Are you trying to deploy cutting-edge Agentic Zapier(Zap) or Make.com( Scenarios) AI workflows or LiveKit voice bots, only to run into state-desyncs, messy tool-calling loops, and broken data pipelines?
We design and deploy heavy-duty enterprise automation. By offloading complex data transformations from expensive no-code tiers into lightweight custom microservices (Node.js, Python) architectures that are lightning-fast, secure, and optimized for self-hosting.
What I Specialize In:
- Self-Hosted n8n Infrastructure: Secure Docker setups on AWS, DigitalOcean, or Hetzner optimized for strict GDPR compliance and zero operation limits.
- N8n (v2.x to v3.0 Mastery): Full migration audits, converting deprecated nodes into modern JavaScript/Python runtimes, and Claude / Groq MCP/Browser Use integration.
- LiveKit & Voice AI: Building ultra-low latency, full-duplex conversational voice bots for booking, customer support, or outbound systems using livekit-agents and Duplex models, LuMay, ElevenLabs, Vapi, Retell, Twilio
- Hybrid Middleware: Highly optimized Node.js, Python, and PHP scripts to serve as custom automation tools or webhooks when visual builders hit a wall.

FAQ
Can you help me migrate from Zapier/Make to a self-hosted n8n instance?
Yes. I specialize in deploying self-hosted n8n using Docker on your cloud infrastructure (AWS, DigitalOcean, Hetzner). I will migrate your workflows, configure task runners, and set up security protocols.
My LiveKit voice agent has a 3 to 4-second delay before answering. Can you fix this?
Yes. This is a common issue with production VAD (Voice Activity Detection) defaults. I write custom Python/Node.js wrappers to override default parameters, cutting down your "speech-end-to-reply" timeline to sub-second responses.
How do you prevent LiveKit agents from breaking when a user interrupts them?
I write specialized Python or Node.js state-management middleware. If a user interrupts mid-sentence, the middleware intercepts the event, safely pauses or rolls back the active background tool-call, and updates the context window instantly.
Do you write custom code inside n8n, Make, or Zapier?
Absolutely. While I use these platforms for visual orchestration, I write custom JavaScript/Python inside Code Nodes—or build standalone microservices—to handle heavy data parsing, pagination, and multi-tier API authentication efficiently.
Can you build both the frontend and AI backend?
Yes. I can handle the complete full-stack implementation, including a Next.js/React dashboard, Python FastAPI backend, AI processing engine, database, authentication, file storage, GPU workers, APIs, and deployment infrastructure.
Can you deploy AI voice models on RunPod or AWS GPUs?
Yes. I can design and deploy GPU-based AI infrastructure using platforms such as RunPod or AWS. The architecture can be optimized for voice generation, cloning, dubbing, concurrent processing, and scalable workloads.
Can I still use ElevenLabs in a custom voice platform?
Yes. ElevenLabs can be integrated alongside self-hosted models where it provides advantages in voice quality, cloning, multilingual support, or specific features. The architecture can be designed so the platform is not unnecessarily dependent on a single provider.
an you integrate AI voice systems with automation and business tools?
Yes. I can connect AI voice systems with n8n, Make, webhooks, REST APIs, CRMs, calendars, databases, SMS/email systems, and other business applications to automate actions after or during conversations.
