With over 15 years of experience as a Java and J2EE developer, alongside my familiarity with Python and PHP, I am confident in my ability to build a robust REST API for your B2B Contact Database. My wide range of technical skills includes expertise in the backend development languages you're seeking, such as Python FastAPI/Flask and Node.js Express.js. I can also bring efficient database management using Postgres, MySQL, or SQLite to organize and leverage your millions of US contacts. In terms of deployment, I'm no stranger to popular cloud services like Heroku and AWS hosting where the API can be safely maintained at scale. I comprehend the vital role played by data security in your business model. Therefore, I assure you of well-implemented authorization through API key authentication to guarantee access only for your authorized customers. One of my key attributes is effective documentation. I will provide clear-cut instructions on how your clients can effectively use the API including endpoints, parameters, authentication and other necessary details. Finally, rest assured that what you'll receive from me will be a highly functional REST API with a properly set-up database while providing backup delivery options like JSON response, webhook push or S3 export when you need them. Let's build this invaluable asset together!

Hi, I can build your REST API for the B2B contact database and make it secure, scalable, and easy for clients to use. -> Import your CSV dataset (millions of US contacts) into a well-structured database (PostgreSQL/MySQL) for optimized queries. -> Develop a REST API (FastAPI/Flask) with endpoints to fetch contacts by company_name and address, returning results in clean JSON format. -> Implement API key authentication to ensure only authorized clients access the data. -> Support multiple delivery options: standard REST JSON, optional webhook push, and optional S3 export for bulk delivery. -> Deploy on AWS, GCP, or Heroku with best practices for reliability and security. -> Provide clear API documentation (endpoints, parameters, authentication) so your clients can integrate easily. I have strong experience in Python (Flask/FastAPI), REST API development, database optimization, and cloud deployment. I can start right away and ensure the API works seamlessly for your customers.

I am the best fit for this project because I have hands-on experience in building secure and scalable REST APIs with large datasets. Your requirement is to migrate a CSV-based contact delivery model into a modern API-first architecture, and I’ve successfully built similar solutions where millions of records were migrated from flat files into optimized databases and exposed via API endpoints.

@lusansapkota

I can build the REST API for your B2B contact database as per your requirements. I have experience in backend development using Python (FastAPI/Flask) as well as Node.js, and I have worked with large datasets in PostgreSQL and MySQL. My approach will include: Importing your existing CSV dataset into a relational database with proper indexing for fast queries. Developing a secure REST API that allows users to query by company name and address, returning results in JSON format. Implementing API key authentication so only authorized clients can access the data. Supporting multiple delivery options: REST JSON response, webhook push, and optional S3 bulk export. Deploying the API on your preferred cloud platform (AWS, GCP, or Heroku) with proper documentation for your clients. Deliverables: Fully functional REST API with public endpoint Database setup and data import Deployment on cloud API documentation with usage examples Timeline: 7 days for development, deployment, and documentation I will make sure the API is reliable, secure, and easy for your clients to use.
