I’m a backend engineer who has recently expanded into AI/LLM systems, combining solid production experience with modern AI-driven development. I hold a Bachelor’s degree in Electrical, Electronics and Communications Engineering from Hacettepe Üniversitesi, and I’ve been working with a fintech startup (H1 Card) since 2021, where I design and deploy backend systems using Python, FastAPI, and Django on AWS. Over the years, I’ve built scalable APIs, microservices, and data-driven systems across a range of projects—from fintech platforms to social applications. I’ve worked with technologies like Nameko, Ariadne (GraphQL), Firebase, and Google App Engine, collaborating closely with frontend teams and stakeholders to deliver reliable, production-ready systems. I’ve also strengthened my engineering practices through the Developing AI Applications with Python and Flask program on Coursera, complementing my hands-on experience building and deploying real-world systems. More recently, I’ve retooled my skillset around AI and LLMs. I now design and build systems that integrate models like Claude, OpenAI, LLaMA, and Gemini into real-world applications. This includes: - Building AI agents and multi-step workflows - Designing systems around MCP (Model Context Protocol) and tool use - Rapid prototyping (“vibe coding”) and shipping AI-powered features - Integrating LLMs into existing backend architectures - Creating chatbots and automation systems powered by modern AI What sets me apart is that I don’t just experiment with AI—I integrate it into production systems with proper backend architecture, scalability, and reliability. Some highlights from my experience: - Backend development for a fintech startup (AWS, FastAPI, Django) - Built microservices and GraphQL APIs for multiple freelance projects - Developed complex Django applications, including Mytichaa (an award-winning Messenger bot in the Bots for Messenger Challenge – Middle East & Sub-Saharan Africa) - Strong background in data handling, APIs, and system design Core Technologies - Python (Django, FastAPI, Flask) - Microservices (Nameko) - GraphQL (Ariadne) - Cloud: AWS, Google App Engine - Databases: PostgreSQL, MySQL, MariaDB, Firebase, Neo4j AI / LLM Stack - OpenAI, Claude, Gemini, LLaMA - AI agents and tool-use systems - MCP and structured context systems - Prompt engineering and evaluation - Backend integration of LLM workflows What I can help you build - AI-powered applications and agents - Backend systems with LLM integrations - Chatbots and automation tools - Scalable APIs for web and mobile apps - Real-time applications (WebSockets, Django Channels) - Data processing and backend pipelines I enjoy working on challenging problems and continuously evolving with new technologies.
