Aashar CK

Aashar CK is a full-stack engineer based in Dubai, UAE, with 5+ years building web applications in React, TypeScript and Node.js. He has worked on both sides of the stack: dashboard interfaces that render large datasets, and the REST APIs, data pipelines and cloud services behind them. His background includes two years of enterprise ETL and data pipeline engineering. He recently built and launched SitesGen, a multi-agent AI SaaS, solo in about a month. He is comfortable owning architecture decisions, tuning database and API performance, reviewing code and documenting what ships.

SitesGen · founder and sole engineer · 2026–

SitesGen is a multi-tenant SaaS for agencies and freelancers who sell websites. It finds local businesses whose websites are letting them down, designs and builds each one a better website from its own photos and reviews, and writes the pitch used to sell it, by email, WhatsApp, LinkedIn or in person. Aashar is the founder and sole engineer. He built and launched it solo in about a month, with subscription billing and a first customer on a paid trial. It is live at sitesgen.com.

SitesGen · eight agents, cost per site

Producing one website costs about $0.33 in model spend on the default models, measured rather than estimated: $0.17 for the design plan, $0.04 for the photo reader, $0.05 for the pitch and a $0.07 share of the scan that found it. The build step costs nothing. Every job records its own tokens and cost, attributed to the member who asked for it. Sonnet was tried for the plan and the pitch and rejected on quality, because the site and the pitch are the product.

TraccoAI · sole architect and engineer · 2025–

TraccoAI is a multi-tenant platform that measures how often a brand gets recommended by ChatGPT, Claude, Gemini and Perplexity, shown as trends over time and side by side against competitors. The problem it solves: brands can't see whether AI assistants recommend them. Aashar is the sole architect and engineer, and built and launched it solo (2025 to present). It is live at traccoai.com.

AI support agent · demo

A chat assistant for a small business's website that answers customer questions using only the business's own help pages and PDF manuals, shows exactly where each answer came from, says "I don't know" instead of making something up, and can check an order or open a support ticket. It is a demo built for Tamp & Bloom, a made-up coffee-equipment shop; it is not a client project. Every reply shows its model, latency and cost.

supabase-rls-check · CLI

A read-only command-line tool that connects to a Postgres or Supabase database and reports the mistakes that leak data: tables without row-level security, policies that allow every row (USING (true)), tables the anon role can write to, SECURITY DEFINER functions exposed to the API, and views that bypass RLS. Each finding has a severity and the exact SQL to fix it, in a Markdown report. Apps built fast, especially with Lovable, Bolt or Cursor, often ship with at least one of these, and with Supabase the anon key is public by design, so row-level security is the only thing between the data and the internet.
