EigenMC
Full-stack FMCSA motor-carrier intelligence SaaS with a public product site, authenticated React dashboard, FastAPI backend, PostgreSQL data model, admin controls, lead workflows, CSV exports, usage limits, and a resilient TypeScript scraping pipeline.
Project brief
Inside the build.
EigenMC is a full SaaS platform for searching, filtering, managing, and exporting FMCSA motor-carrier data. It combines a public marketing site, authenticated dashboard, FastAPI backend, PostgreSQL database, admin tools, and a dedicated scraping pipeline.
The product turns public carrier registry data into a practical workflow for prospecting, contact discovery, lead conversion, follow-up management, account administration, and data access control.

Challenge & response
Turning constraints into a working system.
The challenge
FMCSA carrier data is public, but direct usage is slow and fragmented. Users need fast filtering across large datasets, reliable contact access, CSV exports, and a workflow for turning carrier records into leads.
The platform also needed commercial access controls such as view quotas, contact export limits, subscription states, session limits, and admin-managed user permissions.
On the data side, the scraper had to tolerate blocked responses, proxy failures, interrupted jobs, retry loops, and long-running refresh operations.
The response
Built a React and Vite dashboard with carrier search, URL-backed filters, server-side pagination, CSV export, redacted rows, detail views, lead conversion, lead pipeline management, and admin workspaces.
Implemented a FastAPI backend with JWT sessions, role-based access, carrier search APIs, leads APIs, dashboard snapshots, admin controls, subscriptions, custom limits, export quotas, and PostgreSQL persistence.
Created a modular TypeScript scraper with jobs, tasks, parsers, consumers, checkpoints, persistent retry, proxy handling, database output modes, and operational documentation.
Added a lightweight static product website for EigenMC’s public-facing marketing and conversion surface.
Product capabilities
What the delivery makes possible.
Each capability connects a product requirement to something people can use.
Carrier Search Workspace
Users can search and filter carriers by MC range, keyword, state, city, entity type, FMCSA status, internal status, contact availability, equipment, inspection data, and lead state.
Quota-Aware Data Access
The backend enforces view quotas, redacted carrier rows, export quotas, subscription state, and custom user limits so access can be controlled commercially.
Lead Pipeline
Carriers can be converted into leads and managed across new, follow-up, active, failed, completed, and archived states with notes, follow-up scheduling, bulk actions, and CSV export.
Admin And Super-Admin Controls
Admins can manage users, roles, active status, temporary passwords, assigned admins, allowed sessions, subscriptions, custom limits, and broader platform settings.
Dashboard Snapshots
The API provides single-call user, admin, and super-admin dashboard snapshots to avoid noisy multi-request frontend loading patterns.
Resilient Scraping Pipeline
The TypeScript scraper supports FMCSA SAFER and SMS scraping, checkpoint resume, persistent retry, proxy pools, batch-level retries, MC-level retries, database consumers, and file outputs.
System architecture
A connected delivery, not isolated features.
The static EigenMC marketing site presents the product separately from the SaaS dashboard.
The React dashboard consumes FastAPI endpoints for authentication, carriers, leads, dashboards, admin workflows, dialers, limits, and settings.
FastAPI owns authentication, roles, subscriptions, carrier access rules, lead management, exports, and admin operations over PostgreSQL.
The scraper fetches FMCSA data, parses and normalizes records, checkpoints progress, retries failed work, and writes results to PostgreSQL or export files.
Delivered impact
What changed after the build.
Turned raw FMCSA registry data into a searchable, quota-controlled carrier intelligence product.
Connected search directly to business actions: contact copying, dialer links, CSV exports, lead conversion, follow-ups, and admin-managed access.
Created a production-minded ingestion pipeline that can resume interrupted runs, retry blocked records, rotate proxies, and keep the SaaS database fresh.
