01. About Me

Amir Dehestani

Back-End Developer | AI Specialist | Automation Expert

I'm a passionate backend developer and AI specialist based in Germany, dedicated to crafting robust, scalable solutions that solve real-world problems. With expertise in Python, FastAPI, Flask, and PostgreSQL, I transform complex business requirements into elegant, efficient code that powers modern applications.

My journey in software engineering is driven by a fascination with how technology can automate workflows, enhance decision-making through AI, and create seamless user experiences. From building high-performance RESTful APIs to developing intelligent chatbots and automation systems, I thrive at the intersection of backend development and artificial intelligence.

What I Bring to the Table:

  • Backend Excellence: Architecting and deploying production-ready APIs with FastAPI and Flask, emphasizing clean code, security, and performance optimization
  • AI Integration: Building intelligent chatbots and AI agents that leverage NLP and machine learning to deliver context-aware, conversational experiences
  • Workflow Automation: Designing sophisticated n8n workflows that reduce manual tasks by up to 60%, streamlining operations across multiple platforms
  • Database Design: Creating efficient database schemas and optimizing queries for PostgreSQL and SQLite to handle high-volume transactions
  • Security First: Implementing JWT authentication, secure API design, and following industry best practices to protect data and user privacy

When I'm not coding, I'm exploring the latest developments in AI and automation, contributing to open-source projects, and sharing knowledge with the developer community. I believe in continuous learning and collaboration—technology evolves fast, and so should we.
