AI Engineer | RAG | Vibe Coding | Automation | Shopify | WordPress

Most developers who claim to "𝐛𝐮𝐢𝐥𝐝 𝐀𝐈" ship demos that collapse in production. The RAG pipeline returns wrong chunks. The agents loop. The LLM hallucinates outside its knowledge base. Three weeks after go-live, nobody knows why, and you're back to square one. I build AI systems that hold up after go-live. 𝗣𝗥𝗢𝗢𝗙 ━━━━━━━━━━━━━━━━━━━━━━ ✓ RAG-powered internal assistant (LangChain + FAISS + FastAPI) deployed to production for a US client, handling real daily load with zero hallucinations outside the knowledge base ✓ Real-time Finance Dashboard built on React + FastAPI, replaced client's manual spreadsheets, saved ~3 hours every week ✓ Vibe-coded landing page using v0 + Next js: 94 Lighthouse score, shipped live in 48 hours ✓ Shopify migration: zero downtime, all data preserved, live in 72 hours ✓ 2+ year ongoing partnership with a US SaaS client, 100% JSS, zero cancellations, zero refunds across the full engagement 𝗔𝗜 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 ━━━━━━━━━━━━━━━━━━━━━━ This is the core of what I do. Not demos, systems that run in production under real load with real users. → 𝐑𝐀𝐆 𝐏𝐢𝐩𝐞𝐥𝐢𝐧𝐞𝐬: document ingestion, chunking strategy, vector search, grounded retrieval, hallucination prevention, FAISS · Pinecone. → 𝐋𝐋𝐌 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧: Claude API · OpenAI · Gemini · Ollama, connected to your data, your tools, your workflows. → 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭𝐬 & 𝐀𝐠𝐞𝐧𝐭𝐢𝐜 𝐖𝐨𝐫𝐤𝐟𝐥𝐨𝐰𝐬: multi-step reasoning, tool-calling, memory, orchestration via LangChain. → 𝐕𝐢𝐛𝐞 𝐂𝐨𝐝𝐢𝐧𝐠 𝐃𝐞𝐥𝐢𝐯𝐞𝐫𝐲: Cursor · v0 · Windsurf, AI-native builds shipped in days, not weeks, without cutting engineering corners. → 𝐀𝐈 𝐅𝐞𝐚𝐭𝐮𝐫𝐞𝐬 𝐢𝐧 𝐖𝐞𝐛 𝐀𝐩𝐩𝐬: chatbots trained on your data, document processors, intelligent search, voice interfaces (ElevenLabs , FAL). 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 ━━━━━━━━━━━━━━━━━━━━━━ Business workflows that run without you. Built correctly the first time, no fragile Zaps that break when a field name changes. → 𝐧𝟖𝐧 · 𝐌𝐚𝐤𝐞 · 𝐙𝐚𝐩𝐢𝐞𝐫, from simple triggers to complex multi-step pipelines with error handling and fallback logic. → 𝐂𝐑𝐌 𝐚𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧: lead routing, follow-up sequences, pipeline updates. → Custom webhooks and API-to-API integrations between any two tools. → 𝐀𝐈-𝐞𝐧𝐡𝐚𝐧𝐜𝐞𝐝 𝐚𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧: LLM nodes inside n8n that classify, draft, and decide, not just move data between boxes. 𝗦𝗵𝗼𝗽𝗶𝗳𝘆 & 𝗪𝗼𝗿𝗱𝗣𝗿𝗲𝘀𝘀 ━━━━━━━━━━━━━━━━━━━━━━ Where needed, I build and extend the web layer too, without handing off to a third contractor. 𝐒𝐡𝐨𝐩𝐢𝐟𝐲: custom themes · OS 2.0 · store setup & migration · WooCommerce migration · headless Next.js frontend · app integration 𝐖𝐨𝐫𝐝𝐏𝐫𝐞𝐬𝐬: custom themes · plugin development · Elementor · WooCommerce · speed optimization · REST API · third-party integrations · AI features embedded directly into WordPress, not bolted on later 𝗛𝗼𝘄 𝗜 𝗕𝘂𝗶𝗹𝗱 ━━━━━━━━━━━━━━━━━━━━━━ Every engagement starts with a blueprint: scope, architecture, and tradeoffs agreed before any code ships. Weekly async updates through delivery. No surprises, no scope creep, no disappearing acts. I use Vibe Coding (Cursor, v0, Windsurf, Claude) as a force multiplier, not a replacement for engineering judgment. The architecture decisions are mine. The tools just make the execution faster and give you working software in days, not months.
