About this gig

I am a Senior Software Engineer and AI Architect with over 10 years of professional industry experience. I hold an MSc in Computer Science and Software Engineering, and I specialize in building custom, high-performance backends and production-ready digital ecosystems.

My main focus is on designing autonomous AI multi-agent systems using OpenAI, Anthropic Claude, and Gemini. I build pipelines that don't just reply to text, but actually analyze complex data, run financial forecasting, and execute decision-making workflows.

Technologies I build with daily:

  • Backend & APIs: FastAPI (Python) for high-speed AI pipelines, and Symfony (PHP) for secure, enterprise-scale corporate applications.
  • Mobile & Web: Cross-platform native apps engineered via Flutter.
  • Infrastructure: Full containerization using Docker, secure database architectures, and clean CI/CD pipelines.

I write clean, documented code that matches enterprise standards. Because every project requires a specific architectural design, please shoot me a message with your brief before placing an order. Let's discuss your requirements first.
