Oleg C.

Python Backend Engineer | AI Agents, APIs & Chatbots

Hello! I am a Python Software Engineer with 3.5+ years of experience helping startups and businesses build reliable backend systems, AI-driven automation, and intelligent chatbots.

What can I help you with:

• AI-powered agents and assistants (OpenAI, LangChain, CrewAI)

• Scalable REST APIs and backend services (FastAPI, Flask)

• Telegram, Discord, and Slack bots for automation and customer interaction

• Integration with third-party APIs, payment systems, and internal services

• Crypto-related services and blockchain tooling

Key achievements:

• Designed and implemented AI-powered agents using OpenAI API, LangChain, and CrewAI, enabling smarter automation and improved user interaction.

• Built and launched multi-platform chatbots (Telegram, Discord, Slack) that automated workflows and significantly reduced manual operations.

• Developed and maintained production-grade RESTful APIs used across multiple services and clients.

• Integrated AI and automation tools into existing systems, helping clients increase productivity and create new revenue streams.

• Improved system performance and reliability by introducing async programming, Celery background tasks, and Docker-based deployments.

I focus on solving real business problems, not just writing code.
Open to long-term cooperation and complex, high-impact projects.
