Eight projects.

Paigam

A digital invite platform: one link for the whole celebration.

A paid product I founded and built end to end. Guests get one link instead of a PDF: it opens like a real invitation on any phone, carries RSVP, events, venues and a gallery, and stays editable after it is published. Weddings first, birthdays now live, with more occasions in the pipeline.

  • Self-serve studio: pick a template, type names, dates and venues, and the invitation renders live as you type. No designer in the loop.
  • 17 templates across Sikh, South Indian, Muslim, Christian, Bengali, Gujarati, Royal and Minimal traditions, all driven by the same rendering engine guests open.
  • Clerk auth, customer dashboard, and paid tiers at ₹99 for a single ceremony and ₹499 for up to 8 events, each with its own time and venue.
  • Every invitation publishes to its own slug and opens as a rich card in WhatsApp, the distribution channel the whole product is designed around.

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.

Bezel

A component system with an accessibility bar it has to clear.

A design system published as readable TypeScript source, with a CLI that copies components straight into consumer projects. Tokens for colour, type, spacing and motion, a documented states matrix, and a contrast gate that fails the build on WCAG AA violations.

  • bezel add <component>: source in your repo, not a dependency you fight.
  • Visible keyboard focus on every interactive component, enforced not assumed.
  • Registry generated from source, so the gallery can never drift from what ships.

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.

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

Yash Arya
Yash Arya · Faridabad, IN

I'm Yash, a design engineer in New Delhi. I do the interface work and then ship it: the flows, the type, the states nobody thinks about, and the code underneath. At Pelocal Fintech I'm in the product team, working across several products from the public site to the tooling behind it. The about, careers and contact pages there are mine end to end.

I prototype in the browser rather than in Figma, because that's where a decision actually gets made. A hover that reads well in a static frame can be useless on a phone, and you only find that out by building it.

I also built Paigam, a wedding invitation product I designed, priced and shipped on my own. Twelve templates drawn from specific Indian wedding traditions, because recolouring one design is not the same as respecting twelve.
