MasterChef — Live Competition App

The official platform for a broadcast client, built as sole backend developer. Real-time event flow over WebSockets keeps contestants synchronized with a Twitch livestream despite per-viewer delay, restoring state on refresh, late join or a second device. The hard part was not the sockets — it was migrating 350,000+ user records with zero downtime and no data loss.

KeySignals — AI Platform for SEO and GEO

The company’s AI platform for SEO and GEO, which I designed and built end to end as the only engineer, now live and multi-tenant. 23 agents cover crawling, competitor and keyword research, clustering, planning, writing, optimization and publishing, coordinated by a queue-backed orchestrator. Claude, OpenAI and Gemini are routed per task, and every page is written from a business profile drawn from the site’s own pages rather than from the model’s memory. After publishing it keeps measuring: it asks ChatGPT, Gemini, Perplexity, AI Overviews and AI Mode whether the brand is named or cited, and a weekly Search Console and GA4 loop drafts fixes for pages that slip, which wait for approval before anything goes live.

~/work ❯ cat phasedesk.tsx

PhaseDesk — Team Operations

An invite-only internal system that replaced manual standup, timesheet and leave tracking for every project team. Authorization is enforced in the API rather than the UI across 13 data models: org-wide reads require an explicit admin scope, and project attribution is validated before any write.

~/work ❯ cat elivate-seo-audit.astro

Elivate SEO Audit Tool

A free technical SEO and GEO audit I designed and built: type a domain and it reads the site the way a crawler does — the page, robots.txt, llms.txt and the sitemap — then returns a specific fix per finding across seven areas rather than a 0–100 score. There is no model and no paid API behind it, so the same input always produces the same report. It fetches whatever URL a stranger types, so the fetcher is an SSRF guard first: resolved addresses are checked rather than the hostname, and every redirect hop is checked again.

~/work ❯ cat easinvy-retail.tsx

Easinvy Retail

A multi-tenant SaaS I built as the software developer: GST billing and inventory for small Indian shops — bills, stock, purchases, customers and suppliers, staff attendance, sales reporting and Razorpay subscriptions in one system rather than four. Designed for a phone held one-handed at a counter under shop lighting, so every number is the most legible thing on the screen. Stock is a running figure that can go negative, and the schema treats that as information rather than an error.

~/work ❯ cat serp-reader.ts --status "open source"

SERP Reader

A Chrome MV3 extension that captures search results as structured data, built to run the Elivate SEO study on what AI Overviews cite. The interesting bugs were all in the parser: Chrome and Node disagree about how to parse a malformed hostname, and no test could catch it because the suite runs on Node.
