ABOUT FILAMER DORONIO
I’m a Software Engineer specializing in React, TypeScript, and building scalable front-end systems, with full-stack capability across Node.js, Express, and SQL. For the past several years, I’ve worked on production applications used by thousands of small businesses—modernizing legacy codebases, improving performance, raising test coverage, and delivering full-stack features end-to-end.My background includes business analysis, QA, and user-centered problem solving, which gives me an uncommon strength: I understand how product, engineering, and customer workflows intersect. I’ve participated in a major front-end migration, and collaborated deeply with Product, Design, QA, and backend services.Currently, I’m pursuing my B.S. in Computer Science (WGU) while leveling up my engineering depth and system design skills. My near-term goal is to grow into Senior-level roles and contribute to high-impact product teams.I care about building clean, maintainable software, designing intuitive user experiences, and continuously sharpening my craft as an engineer.Specialties:React • TypeScript • Node.js • SQL • UI Architecture • Component Design • Testing (Jest/RTL) • API Design • Performance Optimization • Design Systems • System Thinking
