SaaS Developer for Hire in Lisbon

About

Building a SaaS product in Lisbon? I am Kirill Strelnikov, a freelance SaaS developer based in Barcelona. Lisbon has one of the most vibrant startup ecosystems in Europe, and I help Lisbon-based founders build their SaaS MVPs fast -- from idea to first paying customer in 4-6 weeks. My stack is Django, PostgreSQL, Stripe, and Docker. Fixed-price contracts, no surprises. I have delivered 5+ SaaS platforms including multi-tenant time-tracking and e-commerce systems.

What I Build

• SaaS MVP development (4-6 weeks to launch)
• Multi-tenant architecture with Django
• Stripe subscription billing (monthly, annual, trials)
• User dashboards and admin panels
• REST API for mobile and third-party access
• AI feature integration (chatbots, content generation)
• Production deployment with Docker and CI/CD

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. Free consultation — we discuss your project, requirements, and timeline. I provide a fixed-price estimate within 24 hours.

2. Development — iterative sprints with demos every 1-2 weeks. You see working software early and provide feedback.

3. Launch — deployment, monitoring, documentation. I handle the entire DevOps stack.

4. Support — ongoing maintenance, bug fixes, feature additions. Many clients continue on a retainer.
