Hi, I’m Sid, a CS freshman at NYU looking for a software engineering internship for Summer 2027.
Why does everyone just say stick to the S&P 500? I wanted to beat it, so I built StockTest to figure out how. A hundred strategies later, every one of them scored after taxes and trading costs, I haven’t beaten it yet. That’s the honest answer, and being able to give it is the whole reason I built the thing.

Backtest a stock-picking strategy against buying and holding the S&P 500, scored net of capital-gains tax, commissions and slippage, because that is where most strategies quietly stop beating the market. Pair any of ten pickers with any of ten timers for 100 strategies, each benchmarked against SPY. The engine runs entirely in your browser, so there is no server and no account.
Built twice, in Python and in JavaScript, with tests that run the same 25 backtests through both versions and check that every one of the 300,508 numbers they produce matches.

An iPhone app on the App Store that turns daily habits into quests: a wake-up stretch, a workout, nutrition, mindfulness and some activity. Clear them all to keep your streak and rank up from E-Rank to Monarch. Apple Health fills in steps, sleep and weight, and everything stays on your phone, with no account and no server.
Took it from idea to the App Store myself: TestFlight testing, Apple’s review, and the support and privacy pages. Workouts only level up after you finish the day before.
