Wasting hours on tasks AI could handle in minutes - but not sure how to plug it into your system? I build production-grade AI automations that save teams 15-30 hours per week and plug into any stack - Java, Python, Next.js, or standalone. Backed by 9+ years of enterprise engineering and real fintech experience. Why me: ▪ AI + strong backend = systems that work at 3 AM with real data, not just in demos ▪ Full cycle: from AI prototype to production deployment - no handoffs needed ▪ Fintech-grade security mindset (ISO 8583/AS2805, PCI-DSS, encryption) What I build: ▪ RAG pipelines - connect LLMs to your data with source-backed answers ▪ Workflow automation - n8n + AI agents that replace manual processes ▪ LLM integration - plug AI into your existing app without rewrites Tech toolbox: Java 21 ▪ Spring Boot 3 ▪ Spring AI ▪ Python ▪ FastAPI ▪ LangChain ▪ Next.js ▪ React ▪ OpenAI API ▪ Claude ▪ Vercel ▪ n8n ▪ RAG ▪ Pinecone ▪ pgvector ▪ Kafka ▪ PostgreSQL ▪ Supabase ▪ AWS ▪ Docker ▪ Kubernetes Have a process eating your team's time?
