🛠️ Core Tech Stack & Enterprise Capabilities ⚙️ n8n (Advanced Workflow Infrastructure) Complex, high-performance automation backends. Because n8n supports self-hosting, it is my go-to choice for enterprise clients looking to bypass high monthly task fees, maintain strict data privacy, and handle advanced conditional logic. I specialize in building custom nodes, executing complex JavaScript/Python snippets within workflows, and deploying autonomous AI agents directly within the n8n ecosystem. 🤖 Lovable, Bolt.new & Base44 (Rapid App Prototyping & MVPs) For startups and fast-moving teams, I utilize Lovable, Bolt.new, and Base44 to rapidly scaffold, prototype, and deploy production-ready web applications. These next-generation, AI-assisted development tools allow me to spin up full-stack MVPs, handle database schema setups, and push functional application updates in a fraction of the time of traditional development. 🔮 Make Integromat (Visual Workflow Architecture) Multi-step visual automations using Make. I don’t just build basic "trigger-action"; I engineer enterprise-grade ecosystems featuring robust global error handling, data stores, router logic, and complex array manipulation. My Make blueprints are built with rate-limiting and webhook optimization in mind to ensure zero data loss. 🎬 HeyGen & Synthesia (AI Video Creation & Digital Twins + Custom Avatars) I handle end-to-end asset creation from custom script formatting and professional voice/tone mapping to template design and multi-scene pacing. I specialize in selecting the right AI spokesperson, setting up high-converting video layouts, and burning-in clean captions/subtitles. I guide executives and brand leaders through the technical process of capturing, rendering, and configuring their high-fidelity Digital Twins and custom voice clones. 📊 Airtable & Monday (Relational Databases & Work OS Architecture) Advanced database architecture, designing interactive Airtable Interfaces, and writing custom JavaScript scripts inside Airtable Automation blocks. Build and optimize enterprise-grade Monday CRM boards, custom dashboards, and cross-board automations. Setting up complex formulas and dependency tracking to mapping out advanced workflows for project management, CRM pipelines, and team operations. ⚡ Zapier (Rapid Business Integrations) I use Zapier to build clean, maintainable, and highly reliable automations across thousands of SaaS applications. Utilizing Webhooks by Zapier, Formatter steps, and custom Code blocks to minimize task consumption and maximize operational uptime for your daily business workflows. 🗣️ Vapi AI, Retell AI, ElevenLabs & Twilio (Conversational Voice AI) I architect ultra-low latency, human-like voice agents. By integrating Vapi AI and Retell AI with ElevenLabs for hyper-realistic speech synthesis and Twilio for programmable telecom infrastructure, I deploy voice bots that effortlessly understand context, handle interruptions, and log structured data directly back into your CRM. 🧠 LangChain & LangGraph (Multi-Agent Systems & State Machines) When standard prompt engineering isn't enough, I use LangChain and LangGraph to build advanced, context-aware AI applications. Cyclical, stateful multi-agent workflows - meaning the AI can loop back, self-correct errors, search internal knowledge bases (RAG), and execute complex reasoning paths before delivering an output. 🐍 Django & FastAPI (Robust Backend & Custom APIs) When no-code tools hit a wall, I write custom code. As a Django developer, I build secure, scalable backend architectures and web interfaces. Using FastAPI, I develop high-performance, asynchronous REST APIs that act as custom middleware seamlessly bridging the gap between your frontend applications, databases, and third-party AI models.
