About

I'm Arun, the solo founder of VoltExam. I build exam-prep apps for the people who keep the lights on, the water running, and the buildings standing — 42 skilled trades and counting: electricians (NEC), CDL hazmat, crane operators (NCCCO), HVAC, plumbers, welders, real estate, and more. Real practice questions, trade-specific calculators (voltage drop, load charts, refrigerant charge), and free cheat sheets on web, iOS, and Android. No VC funding, no fluff — just exam prep that actually helps tradespeople pass. Start free for 3 days at voltexam.com.

Capitol Gains - Track US Senate stock trades in real time. Follow the money.

Under the STOCK Act, every senator must disclose stock trades within 45 days. The data is public — but buried in a government system nobody uses. Capitol Gains makes it accessible: - Live feed of Senate trades, updated every 30 minutes - Filter by senator, ticker, trade size, and date - SMS alerts the moment a new disclosure is filed ($9/mo) - Top tickers, buy/sell sentiment, senator clusters Data pulled from the official Senate eFD system. Free to browse.
