I am a Software Engineer focused on engineering highly scalable full-stack applications, optimizing cloud data layouts, and enforcing robust application security measures. I specialize in translating complex business requirements into stable, secure technical solutions. My core expertise spans designing self-hosted deployment architecture using Oracle Cloud Infrastructure (OCI), Docker, and Supabase to maximize runtime performance and secure data autonomy for multi-tenant SaaS ecosystems. With deep practical experience across the full JavaScript/TypeScript ecosystem, I focus heavily on infrastructure hardening—actively conducting vulnerability mitigation to eliminate vectors like Cross-Site Scripting (XSS) and SQL Injection (SQLi) right from the architectural planning phase. Core Competencies: • Systems Architecture: SaaS System Design, Modular Architecture, Database Schema Optimization • Cloud Infrastructure: Oracle Cloud Infrastructure (OCI), Docker, Supabase, Self-Hosting • Full-Stack Development: Node.js, ExpressJS, ReactJS, PostgreSQL, MongoDB, JWT • Security Hardening: Web Penetration Testing, DevSecOps…I am a Software Engineer focused on engineering highly scalable full-stack applications, optimizing cloud data layouts, and enforcing robust application security measures.
