PromptLock

Agent-aware distraction control for VS Code.

A VS Code extension that watches GitHub Copilot agent activity through in-memory editor events. When you're typing, your browser windows close. When the agent is working, they open. When it needs your approval, they close again. Earn the scroll, then put it down.

  • Two-state machine driven by 7 detection signals — primary is onDidStartTerminalShellExecution.
  • Distraction windows open at iPhone 14 Pro dimensions (393×852) with a mobile UA so Shorts and Reels scroll natively.
  • Hard Lock, Punishment, and Reverse-Dopamine modes. All analytics local — zero external transmission.
  • Replaces a polling approach (v1–v6) that had 17–55s detection delays. Fires instantly.

AI Study Tutor

A subject tutor with four teaching modes and live token streaming.

A Gemini-powered tutor that adapts how it teaches: Explain, Socratic, Revision, or Exam-Focused. Tokens stream over SSE. Voice input drives a 48-bar Web Audio visualizer. Drop an image, get multimodal analysis.

  • Four teaching modes — Socratic mode never gives the answer.
  • Token-by-token SSE streaming with Framer Motion typewriter character animation.
  • LaTeX, code highlighting, exportable notes. Zustand-scoped session memory.
  • Strict TypeScript (zero any), comprehensive Jest suite, IP-based rate limiting at the edge.

XAI-Chain

Explainable AI for blockchain transaction security.

A full-stack Web3 + AI platform that classifies blockchain transactions as malicious or benign, explains every prediction with SHAP values, and stores both on-chain via Polygon Amoy testnet. Every verdict is auditable.

  • XGBoost on 9 transaction features → 100% test accuracy on 10,000 synthetic transactions.
  • SHAP per-feature contributions uploaded to IPFS via Pinata, hash + risk score pinned on-chain.
  • Dockerized FastAPI + Next.js 14 frontend. 6/6 Hardhat smart-contract tests passing.
  • Three-page frontend — landing, analyze, dashboard — with RainbowKit + Wagmi v2 wallet auth.

yash-ui-system

A Turborepo of components extracted from production work.

shadcn-style monorepo with a CLI that copies components straight into consumer projects. Fifteen LanceMart AI components and twelve portfolio primitives, all generalized from real Pelocal production code.

  • npx yash-ui add <component> — no install, just source.
  • apps/gallery preview app with popup previews per component.
  • Three packages: ui, registry, cli. 97% TypeScript.

HAM10000 Skin Lesion Classifier

Deep learning on 10,015 dermoscopy images, 7 lesion classes.

PyTorch pipeline classifying skin lesions with EfficientNetV2-RW-S and ConvNeXt-Tiny ensembles. Focal loss handles a brutal 6,705-vs-115 class imbalance. Grad-CAM heatmaps make every prediction inspectable.

  • EfficientNetV2-RW-S → 94.21% validation accuracy on a single RTX 3060 in ~1.5h.
  • Focal Loss (γ=2.0) for class imbalance · Mixed Precision FP16 for 2× speedup.
  • AdamW + CosineAnnealing LR + best-only checkpointing. Stratified 85/15 split.

ShoeStore

Headless e-commerce with Stripe, Cloudinary, and a Strapi backend.

Next.js storefront on a Strapi CMS. Stripe for payments, Cloudinary for media, Redux for cart state. Mobile-first responsive with a measured 25% engagement lift on mobile.

  • Stripe checkout + Cloudinary-optimized media + Strapi-managed catalog.

§02 — Notes

A frontend engineer who reads SQL,writes Solidity, and ships the README.

Yash Arya
Yash Arya · Faridabad, IN

I'm Yash, a final-year CS student at Bennett University and a frontend engineer interning at Pelocal Fintech, where I'm the sole frontend on an event-operations admin panel running 100+ events and 500+ menu items in production.

Across four internships — LG, a Government of India PSU, ILBS healthcare, and Pelocal — I've learned that good software is less about the stack and more about the seams: the validation that catches a double booking before launch, the cache that turns a 1,000-row table into a 300ms page, the SHAP value that makes an AI prediction defensible.

I work the full spectrum: React + TypeScript dashboards, Solidity on Polygon, PyTorch on a 3060, VS Code extensions, terminal hooks. MERN-first, polyglot when the problem asks for it.
