Hey, I'm Harsh — the mind behind HarshStat.
I'm a quantitative finance enthusiast and systematic trader. Since 2019, I've navigated euphoric bull runs, brutal bear markets, volatility spikes, crashes, and everything in between. Every cycle taught me. Every mistake upgraded me.
I build trading systems, break them, rebuild them, and refine them. I'm obsessed with understanding how markets behave, how systems evolve, and how edges are created.
Beyond trading, I'm a Product Manager. I've built products from zero-to-one, solved real customer problems, and designed systems that scale. I blend product thinking with quantitative logic — a unique lens for understanding how systems behave, fail, and grow.
HarshStat is where I share:
- •Quantitative finance breakdowns and market analysis
- •Systematic and algorithmic trading insights
- •Backtesting engines, models, and trading tools
- •Product thinking and strategy frameworks
- •Growth strategies, decision-making, and mental models
- •My projects, experiments, failures, and learning journey
