I help tech companies and scale-ups solve their most critical technical challenges: from architectures that don't scale to teams that need strategic direction. With over 10 years of experience leading tech projects, I specialize in: What I do best: • Scalable and cloud-native software architecture (AWS/Azure) • Implementing AI in production (LLMs, ML pipelines, Streams, agents, AWS Bedrock) • Technical leadership as fractional CTO for startups and scale-ups • Resilient cloud infrastructure and cost optimization • Modernization of legacy systems and cloud migration How I work: I collaborate flexibly (from a few hours a week to several days a month), perfectly integrated with remote or on-site teams. My approach is pragmatic: solutions that work in production, not castles in the air. Technical Stack: [Backend]: .NET, Python, Java [Cloud & DevOps]: AWS, Docker, Kubernetes, Terraform, CI/CD [AI/ML]: TensorFlow, PyTorch, OpenAI API, LangChain, RAG systems [Architecture]: Microservices, Event-driven, Domain-Driven Design [Databases]: PostgreSQL, MongoDB, Redis, Dynamodb, MySQL Recent Success Stories: • Designed cloud architecture that reduced costs by 40% while maintaining performance • Implemented an AI system that automated lead management, saving 200 hours/month • Led migration from monolith to microservices for the automotive and retail sectors • Built an ML pipeline that processed 10,000 data points per minute in real-time • Data governance for a company's data using Snowflake and DBT Ideal if you need: → Technical mentoring for your development team → Architecture validation before scaling → Temporary CTO while you search for a permanent profile → Implement AI/ML without hiring a full team → Infrastructure and security audit Available for part-time projects
