About the Client

LegalFly is a legal technology platform that helps law firms, researchers, and compliance teams stay up to date with evolving legislation and case law across different countries. By automating the collection of legal documents and making them easily searchable, LegalFly enables professionals to track regulatory changes with speed and accuracy.

THE CLIENT'S  INITIAL REQUEST

LegalFly approached DBB Software to design and build a system capable of automatically collecting, processing, and delivering legal updates from official government and court websites around the world:

Daily Automated Legal Updates

Create scrapers that run every day and gather newly published legal cases, laws, and amendments across a predefined list of countries.

Reliable Multi-Jurisdiction Coverage

Support different document formats, website structures, and publication workflows across government portals.

Unified API for Legal Data Retrieval

Provide an API enabling LegalFly users to request the most recent legal updates and download the full documents.

Scalable AWS-Based Architecture

Design a system that can scale as LegalFly adds more jurisdictions, scrapers, and data sources.

Production-Ready Release Plan

Prepare documentation, deployment plans, and monitoring strategies for smooth transition into production environments.

SOLUTIONS WE DELIVERED

DBB Software designed and implemented a complete backend ecosystem for collecting, processing, and serving legal data at scale:

Discovery & Architecture Planning

Created a Scope Document for Law Web Scrapers, outlining jurisdictions, scraper logic, data flows, API requirements, and operational constraints. This included architectural diagrams, error-handling scenarios, and a release plan.

Daily-Scheduled Legal Scrapers

Built scrapers for each jurisdiction targeting official government and judicial portals using Playwright, Axios, and NestJS. These scrapers run on a daily schedule via AWS Lambda and EventBridge, extract the latest cases or laws, normalize metadata, and upload documents to Amazon S3.

Scalable AWS Infrastructure

Designed an event-driven architecture based on AWS. Used Pre-Built Solutions to quickly bootstrap project with a ready-to-use AWS CDK base and reusable Lambda scaffolding.

Unified Legal Data API

Developed an API that exposes the latest scraped documents and allows users to download full case summaries or legal amendments.

Monitoring & Production Readiness

Implemented logging, error tracking, dead-letter queues, and operational dashboards to track scraper execution, API health, and overall system reliability. Prepared a detailed production release plan, covering deployment workflows, environment setup, and operational guidelines.

RESULTS ACHIEVED

Rapid Prototyping of New Scrapers

Fast development allowed LegalFly to test new jurisdictions quickly.

Automated Daily Legal Coverage

The system now collects updated laws and case decisions every 24 hours.

Scalable Architecture

Built to support additional jurisdictions without architectural changes.
