Codesseum

Codesseum is a Turkey-based software studio building custom web applications, multi-tenant SaaS platforms, and AI-powered products for clients worldwide. We handle e2e product development, from architecture and backend engineering to deployment, scaling, and ongoing support.

Our core stack covers modern cloud-native development with Node.js, Python, and TypeScript, backed by PostgreSQL, Supabase, AWS, and Vercel. We design resilient systems using Docker, event-driven architectures, and high-availability database design, with deep experience in OAuth/PKCE authentication and real-time infrastructure.

What sets us apart is how we work. We integrate AI throughout our development pipeline, letting a lean team deliver at the velocity of a much larger one without compromising on code quality or architectural rigor. We also build AI-native products: LLM-powered features, intelligent automation, voice AI systems, and hybrid ML analytics that turn cutting-edge models into real business value.

Whether you need a SaaS product built from scratch, a complex system architected for scale, or AI capabilities added to an existing platform, we deliver production-grade software that performs.
