Development of Stock Report: Automated Stock Insights Tool

Stock Report is a web-based product that delivers real-time stock insights directly to users via email. Users simply submit their email and preferred stock tickers, and the system automatically generates a detailed stock report and sends it straight to their inbox.

Most retail investors struggle with:

Tracking 52-week highs and lows

Monitoring stock averages

Keeping up with earnings schedules

This information is often:

Spread across multiple platforms

Not beginner-friendly

Not delivered automatically

There was a clear need for a simple, automated way to receive stock insights without logging into multiple tools.

I built Stock Report, a fully automated system that:

Collects user email and stock tickers via a web interface

Fetches real-time stock data from a financial API

Processes and formats the data into a clean report

Sends the report automatically to the user’s email

Supports scheduled report delivery using cron jobs

The entire workflow is fully automated end-to-end.

This was a solo project, and I built everything myself:

Designed and built the full backend architecture

Designed and implemented the web interface

Integrated the backend to the frontend

Managed deployment and production configuration

To support high-fidelity user interactions and a reliable backend service, I built Stock Report using the following technologies:

Backend: Node.js (TypeScript & Express) for building a scalable, secure, and high-performance API

Frontend: Next.js (TypeScript) for a fast, responsive, and SEO-friendly web interface

Email Services: Nodemailer for automated email delivery

Data Source: Yahoo Finance & Alpaca API for real-time stock data

Automation: Cron jobs for scheduled stock reports

Deployment: Render for production hosting for a fully self-built solo project

Version Control: Git & GitHub

User submits email + stock tickers

API validates request

Stock data is fetched from external API

Data is processed and formatted

Email template is compiled

Report is sent using SMTP

Logs are recorded for monitoring

This ensures scalability, reliability, and clean separation of concerns.

One of the biggest challenges was ensuring that stock data remained accurate and consistent across different user-selected tickers. Since users can input any valid stock symbol, there was a risk of incomplete, delayed, or mismatched data.

I integrated reliable financial data sources (Alpaca & Yahoo Finance) and implemented validation checks to confirm ticker availability before processing. I also added proper error handling and fallback responses to ensure that only verified and complete data is used in report generation.

Another challenge was making sure that every metric (52-week high, low, average, last close, and earnings date) aligned correctly with each specific ticker without cross-mixing data.

Solution: I built a strict per-ticker processing pipeline where each stock symbol is fetched, processed, and stored independently before being added to the final report. This guaranteed data integrity and accurate mapping for every user request.

Stock Report demonstrates how a solo developer can build a complete, end-to-end product that delivers tangible value to users. From designing the backend API to creating the web interface, I handled every aspect of development, ensuring accuracy, reliability, and a smooth user experience.

This project reinforced the importance of data validation, performance optimization, and robust error handling while giving me hands-on experience with integrating multiple financial data sources and email delivery systems. Stock Report is a testament to the impact of well-engineered solo projects and my ability to take an idea from concept to fully functional product.
