I am a Backend & Infrastructure Engineer who specializes in designing resilient API architectures, secure authentication systems, and highly optimized containerized environments.
I am a Linux enthusiast with 5+ years of experience using Fedora/RHEL-like systems as my daily driver, backed by a proven track record of migrating legacy enterprise environments into modern, resource-efficient container ecosystems.
- Infrastructure Consolidation & Migration: Led the migration of legacy multi-server environments into a highly optimized, virtualized Linux container ecosystem using VMware vSphere. This significantly reduced hardware overhead, streamlined resource allocation, and cut down maintenance complexity.
- Custom OAuth 2.0 Authentication Server: Designed and architected a custom enterprise OAuth 2.0 provider from scratch to unify fragmented authentication services. Implemented JWT-based migration workflows alongside opaque access tokens for secure session management, including centralized token control features.
- Network Security & Reverse Proxies: Designed and deployed scalable NGINX Reverse Proxy layers to secure internal workloads. Effectively collaborated with network and cybersecurity teams to implement reverse proxy patterns, successfully reducing the infrastructure's external attack surface and public IP exposure.
- API Gateways & Backend Services: Developed and maintained custom API Gateways using Node.js/TypeScript to aggregate disparate third-party APIs, enforce unified authorization rules, and implement granular transaction logging systems.
- Edge Computing & Kiosk Systems: Engineered lightweight, dedicated digital signage and kiosk solutions. Specialized in configuring stripped-down, minimal Linux installations running direct display processes for maximum stability and performance on constrained edge hardware.

Note on Cross-Functional Value: While I am fully dedicated to Backend and Infrastructure roles, my background includes building native iOS apps and web clients. This allows me to design APIs with a deep, practical understanding of how mobile and front-end architectures consume data.
- Transitioning enterprise workflows from Docker to Podman in RHEL-centric environments.
- Deepening knowledge in advanced system design and microservices security patterns.
- Exploring low-level containerization tools and ecosystem compliance.
