ABOUT ME

Hi! My name is Irumi Kikuchi — a dedicated software engineer
with over two and a half years of experience in full-stack development. My work spans front-end and back-end technologies, RESTful APIs, and no-code platforms, with a strong focus on delivering reliable, user-friendly systems.

With a hands-on approach to both development and problem-solving, I’ve contributed to projects involving JavaScript, TypeScript, C#, Python assigned React. I’m also continuing my education in cloud computing and deepening my knowledge in AI and machine learning to grow into more advanced technical roles.

I thrive in collaborative environments and enjoy building practical, scalable solutions that align with real-world needs.

WHAT I CAN DO?

Full-Stack Development
Build scalable and maintainable web applications using JavaScript, TypeScript, React, C#, and SQL.
Cloud Fundamentals
Understand core cloud concepts and services across AWS and Azure, with hands-on practice in setting up basic infrastructure and deployment pipelines.
REST API Integration
Develop and integrate RESTful APIs for seamless communication between frontend and backend systems.
No-Code & Automation Tools
Use platforms like Okta Workflows and Microsoft 365 to automate business processes and streamline workflows.
Network Simulation & Protocol Testing
Design and run container-based network topologies using Containerlab, KNE, and Docker. Develop Go-based test harnesses to exercise protocol-level behavior (BGP, IS-IS) and investigate per-test dependencies and interactions. Build reproducible labs and automate bring-up for CI-friendly networking workflows.
Identity & Access Management (Okta)
Implement and manage enterprise account lifecycle and access controls using Okta and Okta Workflows. Work included SSO (SAML/OIDC), SCIM provisioning, MFA policies, API-driven automation, and workflow-based process automation to improve security and reduce manual provisioning overhead.
Team Collaboration
Communicate effectively in cross-functional teams and contribute positively to agile development processes.
