Work Experience (7)

Dec 2022 - Current
Senior Platform Engineer
HolidayCheck Solution GmbH
  • Defined and drove the evolution of an Internal Developer Platform (IDP), enabling engineering teams to independently provision, deploy, and operate applications through standardized self-service workflows, reducing dependency on platform teams and improving delivery velocity.
  • Architected and implemented Kubernetes-based platform capabilities, including Operators and Custom Resource Definitions (CRDs), establishing reusable deployment and lifecycle management patterns adopted across engineering teams and improving operational consistency at scale.
  • Transformed secrets management workflows by introducing a self-service HashiCorp Vault integration platform, reducing developer onboarding and application configuration setup from hours to under 10 minutes while strengthening security and compliance practices.
  • Improved reliability and operational maturity of a production Kubernetes platform spanning ~300 nodes by driving automation initiatives, enhancing observability practices, and establishing more resilient platform operations.
  • Identified engineering knowledge discovery and operational support challenges, and built an internal AI-powered Retrieval-Augmented Generation (RAG) assistant to improve documentation accessibility, accelerate troubleshooting, and support on-call engineers.
  • Contributed to the AI Enablement strategy by designing Model Context Protocol (MCP) servers and reusable AI agent capabilities, enabling AI assistants to integrate with internal systems and supporting broader engineering productivity initiatives.
Sep 2022 - Nov 2022
Solution Architect (Contractor)
Positive Thinking Company (APAC)
  • Led the frontend modernization initiative by migrating a monolithic Next.js application, jointly developed by 8 engineering teams, into a scalable micro-frontend architecture that enabled team autonomy, independent deployments, and faster release cycles.
  • Designed and implemented a monorepo-based frontend foundation to balance team independence with shared standards, ensuring consistent code quality, CI/CD, reusable components, and unified development practices across micro-frontends.
  • Championed the adoption of an internal design system and shared component library, improving UI consistency, reducing development overhead, and enabling faster product delivery across multiple teams.
  • Improved frontend performance by increasing Lighthouse scores from 40 to 80 and reducing page load time by ~45% through rendering optimization, asset delivery improvements, and frontend architecture redesign.
Jan 2022 - Aug 2022
Senior Software Engineer
E-bot7 GmbH
  • Led the architecture and implementation of a real-time chatbot messaging platform based on Kafka event-driven architecture, building Kafka producers, consumers, backend services, and UI integrations to deliver scalable, low-latency messaging capabilities.
  • Drove the migration of the messaging system from a monolithic architecture to a microservices-based platform, decoupling services to enable independent development, testing, deployment, and release cycles across engineering teams.
  • Led end-to-end testing strategies and implementation to validate critical user journeys across distributed services, improving release confidence, reducing regression risks, and enabling reliable production deployments through CI/CD automation.
Nov 2020 - Dec 2021
Senior Software Engineer
National Australia Bank (Vietnam Development Center)
  • Established the engineering foundation for a greenfield digital mortgage platform by setting up project scaffolding, CI/CD pipelines, development standards, and delivery workflows to enable a newly formed team to build and scale the platform.
  • Analyzed and clarified existing OAuth 2.0 authentication and authorization flows across multiple API Gateway layers within a regulated banking environment, aligning engineering teams on security requirements and enabling reliable integration between backend services.
  • Led the implementation of stub services and service virtualization practices to enable shift-left testing and black-box testing, allowing teams to validate API contracts and integration scenarios earlier in the development lifecycle.
Aug 2019 - Oct 2020
Technical Lead
Dwarvesv Foundation (Offshore team of Reapit)
  • Improved frontend engineering consistency across multiple teams by leading the development of the Reapit Foundations platform, delivering reusable services, shared UI components, and standardized development patterns adopted across products.
