About this gig
Need an AI-powered platform that actually ships? I build production web applications with LLMs at the core - not bolt-on chatbots.
I'm a senior full-stack engineer with 7+ years delivering enterprise systems and SaaS platforms for global clients.
What I build:
- AI Agents & Workflows: Multi-step LLM agents, tool calling, automated decision pipelines.
- RAG Systems: Document Q&A over your own data using vector search (pgvector), with accurate citations.
- Private AI: Self-hosted models via Ollama, so sensitive data never leaves your infrastructure.
- Full SaaS Platforms: Next.js frontend, Django/FastAPI backend, multi-tenant architecture, Stripe subscriptions.
- Automation: n8n, Make.com and Zapier where they fit; custom Python/Celery pipelines where they don't.
Also experienced in ASP.NET Core, Angular, React, PostgreSQL, Docker and Azure.
Every build ships with clean architecture, documented APIs, and deployment to your cloud.
Message me with what you're trying to automate or build. I'll tell you honestly whether AI is the right tool for it before you order.

FAQ

Will the web application be secure and scalable?
Absolutely. By utilizing Python Django for the backend, your system benefit from built-in security against common vulnerabilities. I build using Clean Architecture and optimized database schemas to ensure easy horizontal scaling.
