Project Challenges

Our client, being an innovator in the field of Legaltech, embarked on an ambitious journey to create a transformative data management product.

How does legal document automation work in general? It streamlines the contacts creation process by collecting user information, and integrating these details into designated fields within a document template, such as dates or client names. In numerous law firms, where the handling of repetitive legal documents is common, this approach replaces the conventional method of manually updating variable texts.

The goal of our client was to develop a sophisticated web-based solution document automation tool capable of parsing Word and PDF documents from various external systems, and extracting legal terms, and other vital information to generate then definitions from this data, aiding in the creation of new legal agreements and the analysis of existing ones.

However, our client faced a significant hurdle. The collaboration with their initial development team had ceased, leaving a messy codebase and necessitating the search for a new, more reliable, and competent software development partner, who would be able to continue the work started, improve the codebase, and create all the necessary features for the product.

Thus, the company was looking for highly talented and skillful backend engineers to join their in-house team who could fulfill the following goals:

  • Complete the work started on the previous project, refine the existing codebase, and optimize the platform for performance;
  • Collaborate closely with the client’s team to deliver a product that aligns with their high standards and goals;
  • Help to manage the project, define the scope of work, and set deliverable deadlines;
  • Seamlessly integrate the platform with various third-party systems to access and process Word and PDF documents;
  • Enhance the web-based solution with the features of quick parsing, analyzing, and structuring legal data, that can be further used to create new legal contracts and analyze the old ones;
  • Ensure the document automation tool is user-friendly both in the creation of new legal agreements and the analysis of existing ones, quickly managing any legal definitions and creating contracts;
  • Help with the product refinement, adding new features, and aligning the platform with the client’s product ecosystem;
  • Provide ongoing technical and developmental support to continuously refine and improve the product.

Thus, the client was in search of a team of on-demand developers possessing not just technical expertise, but also a deep understanding of LegalTech solutions. The project demanded a team capable of enhancing the web-based legal document system with new features, seamless integration with third-party systems, and robust capabilities for analyzing and generating legal content.

A critical aspect of their search for a software development partner was finding a team that could deal with a messy codebase that was left from the previous software provider, grasp perfectly their product vision, fit in the company culture, and has a suitable geographic location.

Fively portfolio, showcasing a diverse range of projects including complex web-based solutions, demonstrated our capability to handle such a project. After a detailed discussion with our development team, we delved into the project specifics and evaluated the existing product's status, the client was confident in selecting Fively as their development partner.

This marked the beginning of a collaborative and dynamic partnership, with the project officially kicking off in July 2023, setting the stage for a significant leap in LegalTech innovation.

How We Created a Top-Tier Document Automation for Lawyers

Right from the start of this innovative LegalTech project, the Fively team worked hard to build the solution our client dreamed of. Despite encountering a challenging and disorganized codebase, our dedication to the project has been nothing short of inspiring, so we quickly formulated a strategy to restructure and streamline the project. That’s how it was in detail:

Project Architecture: In our journey to develop an all-encompassing platform for PDF legal document automation and management, Fively engineers employed a sophisticated and robust architecture. Utilizing a blend of high-performance technologies, we've created a solution that's not only efficient but also scalable and user-friendly.

Here's a breakdown of the technologies we used and their roles in the project:

Python - we chose it for its versatility and efficiency in handling data-intensive tasks. Python's extensive libraries and frameworks made it an ideal choice for the backend development of the legal document automation platform;

FastAPI - leveraging FastAPI, we created high-performance APIs that helped us ensure that our platform was not only fast but also capable of handling concurrent requests effectively;

Django - it was utilized to ensure rapid development and pragmatic design. It greatly simplified the process of building a secure and maintainable platform, making it a perfect choice for managing backend operations;

PostgreSQL - this database management tool offered the reliability and scalability required to handle complex data operations and queries, and quickly automate legal documents processing, ensuring data integrity and efficient management;

Celery - an asynchronous task queue, Celery was crucial in handling distributed real-time processing, working in tandem with RabbitMQ to manage task queues efficiently.

RabbitMQ - this message broker enabled effective handling of communications between different services and components, ensuring a seamless, decoupled, and reliable messaging system.

Redis - employed as an in-memory data structure store, Redis was used for caching and as a message broker, significantly enhancing the tool's performance and responsiveness;

RPC (Remote Procedure Call) - used to enable the legal document automation platform with different services to communicate with each other over the network, RPC helped in making the platform more modular and distributed;

Microservices - the platform was built using a microservices architecture, which allowed for the development of independently deployable modular services. This approach enhanced the flexibility and scalability of the platform, enabling it to efficiently handle diverse and evolving legal document processing needs.

These technologies, working in harmony, have enabled Fively to craft an advanced, comprehensive platform for legal document automation and management, and paved the way for a solution that not only meets the current demands but is also ready for future advancements.

Team Structure: To successfully execute the project’s ambitious scope, Fively bolstered the client's team by integrating 4 of our seasoned Python engineers and 1 QA specialist. This strategic team expansion enabled us to blend our expertise seamlessly with the client's vision, ensuring a robust and comprehensive development process from start to finish.

Communication tools: Right from the start of this document automation project for lawyers, we established efficient communication channels with the client's team, ensuring a seamless and productive development process. Leveraging the power of virtual meetings, we fostered an environment of open dialogue and collaboration on any technical questions, choosing fitting tools and solutions, or improving project architecture.

We used emails as a reliable medium for detailed follow-up exchanges and documentation, while Slack we used for prompt and convenient in-team interactions, keeping everyone connected and informed. Regular calls and standups also were integral in maintaining a clear view of the project's progress and addressing any emerging ideas or challenges.

The chosen strategic approach, architecture, and communication style helped us to work with the client’s team in continuous improvement and kept us unified in our pursuit of transforming the platform into a top-tier legal document management solution. As a result, it helped significantly simplify the backend codebase, unlocking the potential for greater efficiency and functionality.
