Roman Buhyna

I'm a Senior Software Engineer with 8 years of experience building scalable backend systems, modern web applications, and AI-powered platforms that deliver real business impact.

🧠 AI/ML Expertise: I integrate advanced AI/ML solutions including LLMs (OpenAI, Anthropic), NLP, object detection, and predictive analytics — driving intelligent automation and user engagement.

🔧 Backend Engineering: My core stack includes Python (FastAPI, Django, Flask) and Node.js, building RESTful and GraphQL APIs, microservices, and secure, high-performance backends.

🧩 Automation & Integrations: I streamline workflows with Zapier, Make.com, and n8n, connecting AI systems, APIs, and databases to eliminate manual tasks and boost efficiency.

📈 SaaS & Data Platforms: From MVPs to enterprise systems, I deliver backend solutions with real-time processing, secure authentication, and scalable architecture — deployment-ready with Docker, AWS, and CI/CD pipelines.

🎨Frontend Designing: I also work with modern frontend frameworks like React, Vue.js, and Next.js when full-stack support is needed.
