What I build: AI Agents and Custom Automation I design AI agents, multi-agent workflows, and custom business process automation that handle real operations end to end: lead qualification, follow-up, document processing, customer support triage, and internal ops. Built with custom code and API integrations (webhooks, REST, third-party platforms), with human-in-the-loop approval where it matters, using OpenAI and Claude. I architect these as clean, maintainable systems, not brittle scripts. Full-Stack SaaS and MVPs I take validated ideas to working, multi-tenant SaaS products: user accounts, dashboards, admin panels, role-based access, subscriptions, and reporting. Stack: Next.js, React, Node.js, Nest.js, Python, FastAPI, Supabase, PostgreSQL, Stripe, and cloud deployment on AWS and GCP. Milestone-based delivery with a working build at every checkpoint. RAG and LLM Applications I build retrieval-augmented generation (RAG) systems and document intelligence pipelines: chat-with-your-documents, knowledge bases, structured extraction, and grounded, no-hallucination outputs. Using LangChain, Pinecone, Chroma, vector embeddings, prompt engineering, and contextual memory across GPT-4, Claude, Llama, and others. CRM and Lead Management Systems I build AI-driven lead management and CRM platforms: multi-source lead intake, AI lead scoring and qualification, automated follow-up sequences, pipeline tracking, and conversion reporting in a single dashboard.

Most wasted AI budget comes from building the wrong thing first. The businesses I work with usually have the same problem: manual processes, disconnected tools, and leads or support tickets that sit untouched for hours. I replace that with systems that respond in seconds and run 24/7 without adding headcount. ➤ 𝗪𝗵𝗮𝘁 𝗜 𝗕𝘂𝗶𝗹𝗱 ✔ AI Agents and Agentic Workflows: autonomous and tool-using agents, multi-agent systems, function calling, MCP integrations (LangChain, LangGraph, CrewAI) ✔ AI Integration: connect OpenAI, Claude, and Gemini to your existing tools, CRM, and internal systems so AI works inside the workflows you already run ✔ AI Automation: n8n, Make, and Zapier workflows to automate lead qualification, CRM updates, email follow-up, reporting, and business processes ✔ AI Chatbot Development: context-aware support and sales chatbots for web, WhatsApp, and Slack, connected to your knowledge base, CRM, and calendar ✔ AI Voice Agents: inbound and outbound calling, AI receptionists, appointment booking, lead qualification (Vapi, Retell AI, ElevenLabs, Twilio, Deepgram) ✔ RAG Systems: knowledge bases grounded in your real documents with semantic search and vector databases (Pinecone, pgvector, Qdrant, ChromaDB) ✔ AI SaaS Platforms: full-stack development with multi-tenant architecture, auth, Stripe billing, dashboards, and deployment included ✔ Backend and API Integration: Python, FastAPI, Node.js, PostgreSQL, Supabase, REST APIs, webhooks ➤ 𝗦𝗵𝗶𝗽𝗽𝗲𝗱 𝗪𝗼𝗿𝗸 ✔ NFC-linked commerce platform for music artists: artist storefronts, product discovery, sales and tap analytics dashboards ✔ Event ticketing platform: event creation, checkout, and payment flows with fintech integrations ✔ Production data warehouse on Amazon Redshift for a Berlin climate-fintech company, delivered across structured milestones ✔ AI recruiting platform: trigger-based candidate sourcing with LLM scoring and automated write-back to Google Sheets ✔ Multiple production automation pipelines connecting CRMs, payment systems, and marketing tools Every system ships documented, deployed, and maintainable by your team.

Senior Full-Stack Developer | Scalable Architecture | Performance & Stability If your platform is struggling with latency, unstable deployments, or a codebase that’s becoming a bottleneck, I can help. I specialize in turning "scaling pains" into high-performance, predictable systems. What my 5+ years of experience bring to your team/project: Performance Optimization: I recently optimized an LMS by resolving OpenAI RAG latency. By designing a Sidecar container to handle AI streaming in parallel, I delivered real-time responses while the main backend handled data storage which massively improved the user experience. DevOps as a Standard: I utilize infrastructure as code (Terraform, Cloudformation etc) as a best practice for deployments. Whether it's AWS, GCP, or OVHcloud, I ensure your environment is version-controlled, reproducible, and scales behind automated load balancers. Bulletproof Auth & Payments: I prioritize security with HTTP-only cookie auth and have integrated complex subscription flows using Stripe and Square. Zero-Downtime Releases: I implement CI/CD pipelines that allow you to ship code with a single trigger that require no maintenance windows, no user interruptions. 🛠 The Toolkit Backend: Node.js (Fastify/Express), Python (Django/FastAPI), Supabase, Parse Server. Frontend: React, Next.js, Angular, TypeScript, Tailwind CSS. Infrastructure: Docker, Kubernetes, Terraform, AWS, Redis. Real-Time: WebSockets, NATS, MQTT. The Bottom Line: You get clean, maintainable code, measurable speed improvements, and a partner who understands the "founding team" hustle. I’m available to start immediately and operate with a high-availability mindset. Let's hop on a call and discuss further.
