We’re looking for a seasoned Full Stack Developer to help build a system that scrapes multiple business-for-sale listing sites, normalizes the data, and provides a user interface to review and evaluate potential investment opportunities. This project is expected to last around 3 months, with the possibility of extension based on progress and evolving needs.

REQUIREMENTS:

• 3-5 years of full stack development experience
• Strong proficiency in TypeScript (front-end and back-end)
• Experience with serverless or container-based architectures (GCP, AWS, or similar)
• Solid understanding of SQL databases (Postgres, SQLite)
• Familiarity with web scraping techniques and libraries
• Knowledge of RESTful API design and best practices
• Experience integrating large language models or working with AI/ML APIs
• Strong sense of ownership, with the ability to work independently and deliver high-quality results
• Strong communication skills in both English and Spanish

Data Scraping & Integration

• Develop daily and on-demand scrapers to fetch listings from multiple sites
• Normalize and store data in a shared schema (e.g., price, revenue, location, etc.) in SQL databases

Application Logic & APIs

• Implement serverless functions or container-based microservices (Cloud Run / Cloud Functions or similar) to handle various workflow steps
• Set up triggers to manage scraping, data normalization, and model evaluations

UI Development

• Build front-end components (TypeScript & React) that allow users to:
• Trigger and monitor scraping
• Filter and display listings
• Enter and search business theses/strategies
• Input prompts and model combinations
• Review listings flagged for due diligence

Model Integration

• Integrate with large language models (OpenAI, Claude, Gemini, Grok) to evaluate each listing against defined theses
• Store model prompts and outputs in a database
• Provide an interface to trigger model evaluations on-demand

Due Diligence Workflows

• Implement a progression system for listings flagged for further review
• Store additional due diligence data and allow manual promotion of listings

Performance & Maintenance

• Optimize system for scalability (potentially on Google Cloud Platform or Cloudflare)
• Write clean, maintainable code and ensure robust data handling and security
