The problem
Market research across multiple asset classes is difficult to keep current and usable when collection, indicators, and presentation are disconnected.
What I built
- Built Python and PostgreSQL data workflows for 500+ stocks, 20+ indices, and 200+ cryptocurrencies.
- Built the Next.js and Chart.js product interface, automated screening, Stripe billing, and Dockerized deployment.
Reliability and safeguards
- Owned data freshness, scheduled workflows, deployment, billing behavior, and ongoing maintenance.
Outcome
A long-running fintech decision-support product; no investment-performance or revenue claim is made.
