Cover image for Shopify Case Study — Designing
Shopify Case Study — Designing for Seamless E-commerce Experiences This case study explores how thoughtful UI/UX design can simplify and elevate the online selling experience using Shopify as the foundation. The focus was on understanding how users interact with e-commerce platforms — from product discovery to checkout — and identifying opportunities to improve clarity, speed, and conversion. 🔍 What I worked on: • Analyzing user journey from landing to purchase • Improving product page structure and hierarchy • Simplifying navigation and reducing friction • Enhancing mobile shopping experience • Creating a clean, conversion-focused UI 💡 Key insights: • Users value speed and clarity over heavy visuals • A well-structured layout directly impacts conversion rates • Mobile-first design is critical for modern e-commerce • Trust elements (reviews, pricing clarity, CTA) play a major role 🎯 Outcome: A refined, user-centric shopping experience that feels intuitive, fast, and reliable — helping users make decisions with confidence. This case study reflects my approach to solving real-world design problems through research, structure, and simplicity. Open to feedback and opportunities 🚀

Cover image for Most RAG systems have two
Most RAG systems have two problems that nobody talks about enough. The first is semantic drift — your retriever pulls in chunks that look relevant (high cosine score) but don't actually answer the question causally. Ask "Why did Lehman Brothers collapse?" and you'll get back chunks about the 2008 housing crisis — same vocabulary, but those are the consequences, not the cause. Cosine similarity can't tell the difference. The second is context poisoning — even if each individual chunk is okay, a window full of semi-relevant chunks confuses the LLM. It attends to all of them, averages them out, and hallucinates. VORTEXRAG fixes both. It's a 7-layer pipeline I built specifically around these two failure modes. Each layer has a specific job:

A browser-based tool that turns any GitHub repo into an instant, visual "intelligence report." You paste a GitHub URL and get a full dashboard back — no sign-up, no auth, no friction. It's a developer-tool / analytics product. Core features Health Score (0–100) — production-readiness rating across 7 quality dimensions, with letter grades Language pie chart — interactive breakdown of language composition Commit heatmap — GitHub-style 52-week activity grid Contributor rankings — top 10 contributors with avatars + metrics Smart dependency detection — parses package.json, requirements.txt, Cargo.toml, go.mod, pom.xml, Gemfile File tree browser — collapsible directory viewer with file-type icons README rendering — full GitHub-flavored Markdown with syntax highlighting Share cards — export a PNG summary for social media Tech stack LayerTechFrontendReact 18, Vite, Tailwind CSS, Recharts, react-markdownBackend (optional)Python 3.12, FastAPI, httpx, file-based caching, slowapi rate limitingDeployGitHub Pages (frontend), Railway (backend, optional) How it works The frontend runs entirely in the browser and talks directly to GitHub's REST API — that's why the live demo needs no setup or login (limited to ~60 requests/hour unauthenticated). The FastAPI backend is optional, and only exists to add caching and rate-limit relief when you self-host. Run it locally Or docker compose up --build.

Cover image for Built Afterglow with stitch by google a
Built Afterglow with stitch by google a two-person ritual app for neurodivergent humans. You share how your day felt as a glow, not words; a hard day is met with a slower, steadier light, never amplified. Designed every screen in Stitch: imported my portfolio's tokens, generated the screens, and animated the breath, the glow-merge, and an SVG shader with in-place edits. Then shipped it as a working PWA. Prototype - https://dashing-strudel-880ce8.netlify.app ·  https://www.loom.com/share/c90b979dafc340e99fe7f3a13586cc9e Calm by default. No streaks, no scores. Presence that remembers.
