I previously worked at Microsoft, where I contributed to large-scale cloud and platform engineering projects, including high-availability backend systems, service dependency modeling, deployment automation, and infrastructure reliability improvements. My experience also includes enterprise software development at Oracle and independent architecture work for backend, data, and AI-related systems. My main strengths are backend architecture, API design, Python/FastAPI, Java/Spring Boot, PostgreSQL, Docker, cloud-based systems, and AI/ML integration. I am especially good at taking complex business requirements, breaking them into clear technical plans, and delivering clean, maintainable, production-ready solutions. Recently, I have been building AI-powered products that combine software engineering, data pipelines, machine learning, and real-world automation. One example is an AI-assisted sports motion analysis platform using wearable sensor data, Flutter mobile apps, FastAPI backend services, PostgreSQL, and rule-based/ML-based evaluation logic. This project gave me hands-on experience in AI engineering, data processing, API integration, deterministic rule engines, and practical model-assisted product development. I can help clients with: Backend system design and implementation Python/FastAPI or Java/Spring Boot backend development REST API design and database integration AI API integration with OpenAI, Hugging Face, or similar services Business process automation and AI agent workflows Data pipelines, rule-based engines, and backend reliability improvements Codebase audit, refactoring, testing, and production readiness I am comfortable working independently, joining existing projects, auditing complex codebases, and communicating clearly with both technical and non-technical stakeholders. I value practical solutions over unnecessary complexity, and I focus on building systems that are reliable, understandable, and easy to maintain. I am open to remote freelance and contract opportunities, especially in backend engineering, AI automation, Python/FastAPI development, system architecture, and AI-powered software products. less
