Python Developer for Hire in Madrid

About

Need a Python developer for your Madrid-based project? I am Kirill Strelnikov, a freelance backend developer specializing in Python, Django, and AI integrations. While I am based in Barcelona, I work remotely with clients across Spain, including Madrid, and have delivered 15+ commercial projects for businesses of all sizes. Whether you need a SaaS platform, an AI-powered chatbot, a REST API for your mobile app, or a custom business automation tool, I can help.

What I Build

• Custom web applications with Django
• REST APIs for mobile and web
• SaaS platforms with multi-tenant architecture
• AI chatbots with OpenAI and LangChain
• Database design and optimization (PostgreSQL)
• Business process automation
• Telegram and WhatsApp bots

My tech stack: Python, Django, Django REST Framework, PostgreSQL, Redis, Celery, Docker, OpenAI API, LangChain, Telegram Bot API, Stripe, FastAPI, Nginx, Git, Linux.

How I Work

1. Discovery call — We discuss your project scope, tech requirements, and business goals. I ask about your existing systems, expected load, and timeline.

2. Architecture & estimate — I design the database schema, API structure, and deployment plan. You receive a fixed-price quote within 24 hours.

3. Iterative development — I ship working features every 1–2 weeks. You review demos on a staging server and give feedback before I move on.

4. Launch & handover — I deploy to production, set up monitoring, and hand over full documentation. Code ownership is 100% yours.
