Job Title: Backend Developer for Fast & Accurate Bank Statement PDF Data Extraction Description: I am developing a web application and have completed the frontend. I need a skilled developer to implement the backend functionality for a simple but high-performance bank statement PDF converter. Project Overview: The core functionality involves extracting data from bank statement PDFs with the following key requirements: High speed: The data extraction must be very fast, even for large PDF files. 100% accuracy: Extracted data must be precise without errors. Scalability: The solution should handle large PDFs with many pages and process a high volume of documents reliably. Responsibilities: Develop backend functionality to parse and extract structured data from bank statement PDFs. Ensure the extraction logic handles various bank statement formats robustly. Optimize for performance and accuracy. Integrate the backend with the existing frontend (API endpoints or other communication methods). Provide documentation or notes on usage and limitations. Skills Required: Strong experience with PDF parsing and data extraction libraries/tools (e.g., PyPDF2, pdfminer, Apache PDFBox, or others). Proficiency in backend development (Node.js, Python, Java, or preferred language). Experience optimizing for speed and accuracy in data processing tasks. Ability to handle large files efficiently. Attention to detail and commitment to delivering error-free results. Additional Info: The frontend is already done, so your focus is on backend functionality. Clear and maintainable code is preferred. Communication during the project is important to clarify requirements and progress.

I have 7+ years of full-stack experience and can deliver a high-speed, 100% accurate, and scalable Java Spring Boot backend for bank statement PDF extraction, fully integrated with your existing frontend. Understanding of Your Requirements: 1. Fast & Accurate Extraction – Parse large, multi-page PDFs in minimal time with error-free financial data. 2. Scalable & Flexible – Handle multiple large documents concurrently and adapt to varied bank statement formats. 3. Seamless Integration – Provide secure, smooth API communication with the existing frontend. I understand that for financial data, speed and precision must work together — even a single error can have serious implications. Key Approach: • Tech Stack: Java 17, Spring Boot, Apache PDFBox/iText for parsing, Apache Tika for metadata, regex for structured data. • Performance: Memory-efficient streaming, multi-threaded parsing (Fork/Join), caching for repeated formats. • Accuracy: Validation layer to ensure correct totals, dates, and transaction details. • Scalability: Asynchronous processing with RabbitMQ/Kafka, Dockerized for AWS/GCP/Azure. • Security: JWT-authenticated REST APIs for file upload, extraction, and status checks. Workflow: 1. Analyze sample PDFs & define parsing templates. 2. Implement modular extraction (text, parsing, validation layers). 3. Optimize for speed & large-file handling. 4. Integrate with your frontend via secure endpoints. 5. Test (unit & load) and deliver documentation.
