The 7th version of my portfolio. I built it mainly with AI just for fun. It pulls together everything I do into one place. The design leans heavily into a technical, coding-like aesthetic. Most of the UI is built from scratch: custom components, code-editor and terminal inspired layouts, and data visualizations that make things like tech stacks and impact easier to explore. The idea is that the portfolio itself should feel like a real engineering surface, not a generic marketing site. Performance and accessibility were treated as core features, not afterthoughts. The site is tuned for fast loading, smooth interactions, and strong scores across Lighthouse categories (Performance, Accessibility, Best Practices, SEO). The same principles I used here are documented in my in-depth frontend performance guide, which walks through how to engineer for 100/100/100/100 Lighthouse scores and production-grade UX: https://zalt.me/blog/2025/11/frontend-performance If you want to see the exact tech stack and more implementation details for this site, you can find them on the dedicated project page: https://zalt.me/projects/zalt-portfolio-v7 The portfolio also includes a blog where I write deep dives on coding, AI, architecture, and performance, along with a catalog of projects, services, and community contributions. The goal is simple: make it easy for someone to understand what I do, what I care about, and the standards I apply when I build software.
