Hereby: AI-Powered Contract Management Platform

An AI-powered contract management platform for end-to-end contract workflows—preparation, review, execution, and post-signing operations—augmented with OCR + LLM/agent features. I contributed across product management and development (backend, AI) in Python.

Project Overview

Hereby (https://hereby.me) is an AI-powered contract management platform built to reduce the friction of contract operations. The product combines a document viewer + structured data + collaboration history, with AI assistance to identify missing fields, extract key terms, and support downstream workflows.

Contract viewer with action history and an AI assistant panel for review guidance.

My Role

  • Software Engineer (backend + AI)
  • Product management & execution (requirements → delivery)

Timeline

  • Dec 2024 - Present

Tech Stack

  • Backend / AI: Python
  • AI: LLM-based features, agentic workflows
  • Inference: vLLM (internal inference infrastructure)
  • Document: OCR + contract processing pipeline

Key Contributions

AI Inference Infrastructure (vLLM)

  • Built internal LLM inference infrastructure using vLLM to support product workloads
  • Focused on production constraints: reliability, latency, and operational visibility

OCR + AI-Based Contract Processing

  • Designed and implemented an OCR + AI processing structure to convert contract documents into structured, usable data
  • Integrated extraction and validation outputs into product workflows (review and follow-up actions)

Agentic Contract Workflows

  • Implemented agentic workflows that assist contract management tasks (e.g., identifying missing/incorrect fields, guiding users through next steps)
  • Iterated on prompt/tooling patterns to fit real product UX and quality expectations

Product Execution

  • Drove execution from requirements to delivery: scoping, milestone planning, and cross-stakeholder alignment
  • Connected product needs with implementation details to ship quickly without sacrificing correctness

Results

  • Shipped backend + AI features that improved contract review and operational workflows
  • Established a scalable foundation for OCR/LLM-powered contract automation

Notes

  • Team affiliation: FIG (Firma Innovation Group)
