Veestro

Inspiration

Everybody always says do your own research but in most cases no one actually knows what to research. We wanted to create a structured, disciplined approach that guides users through professional-grade stock analysis step-by-step.

What it does

Veestro walks investors through a 12-step workflow covering market conditions, sector analysis, stock screening, fundamentals, valuation, competitive moats, technical trends, analyst sentiment, and position sizing all powered by real-time data from multiple financial APIs.

How we built it

Next.js 14 with TypeScript, Prisma for database management, and a modular data adapter architecture integrating FMP, Alpha Vantage, Polygon, Yahoo Finance, Federal Reserve, and SEC EDGAR APIs. Deployed on Vercel with intelligent caching and fallback strategies.

Challenges we ran into

API rate limits, deprecated endpoints (SEC EDGAR 404s), restrictions, and ensuring sufficient historical data for technical analysis. We built robust fallback mechanisms and adapter patterns to handle these gracefully.

Accomplishments that we're proud of

A resilient multi-source data architecture with automatic failover, comprehensive 12-step analysis workflow, real-time market data integration, and a clean UI that makes complex financial analysis accessible to everyday investors.

What we learned

Financial APIs are fragile endpoints change, rate limits vary, and free tiers have significant restrictions. Building adapter patterns with fallbacks is essential. Also learned the importance of caching strategies for cost and performance optimization.

What's next for Veestro

Portfolio tracking and monitoring alerts, backtesting capabilities, AI-powered stock recommendations, mobile app, social features for sharing analysis workflows, and premium data integrations for institutional-grade insights.
