Presentation
My career is defined by taking complex legacy systems and transforming them into modern, high-performance architectures. At Rakuten, I led the redesign of the Ichiba notification system, migrating it to a cloud-native, event-driven architecture using Java/SpringBoot and Kafka, which earned me an MVP Project Award.
What I Bring to Your Project:
- Full-Stack Ownership: I build and deploy complete solutions, from React frontends to robust Java/Spring Boot backends.
- AI & LLM Integration: Expertise in developing AI API Gateways on Azure (OpenAI) for usage control, cost analysis, and high-performance reporting.
- Scalable Cloud Infrastructure: 3+ years of Azure expertise, including Kubernetes, Docker, and Terraform for Infrastructure as Code (IaC).
- Performance Optimization: Proven track record of reducing batch processing times by 60% and ensuring 100% data integrity during complex migrations.
Technical Toolkit:
- Languages: Java (10 yrs), C++ (5 yrs), Python, JavaScript, TypeScript.
- Backend: Spring Boot, Microservices, Kafka, Akka, PostgreSQL, CosmosDB.
- Frontend: React, TypeScript, JSF, JavaFX.
- DevOps: Azure, Kubernetes (AKS), Docker, Terraform, Jenkins, GitHub Actions.
I thrive in environments that require technical leadership, strategic thinking, and a focus on efficiency. Whether you are a startup looking for a founding engineer or an enterprise needing a cloud migration expert, I deliver results that align with your business goals.
Background
Key Contributions:
- End-to-End Development: Architected and developed the complete Java/Spring Boot backend and React/TypeScript frontend to support complex AI-driven environmental data.
