PrismCV resume builder and job tracker — ATS check landing at prismcv.com

Overview

Designed, built, and operate PrismCV end-to-end as a paid SaaS at prismcv.com. The product solves a job-hunter pain point I had myself: maintaining one canonical resume while branching tailored versions for individual postings, and tracking every application through to offer. The platform pairs a 13-point ATS scoring engine with Claude-powered tailoring, aggregates jobs from six remote-job boards plus Greenhouse and Lever feeds, and exposes the full workflow through both a Stripe-billed web app and a 34-tool MCP server that AI agents (Claude Desktop, Cursor, Claude Code) can drive directly.

Resume Engine

A multi-version resume system that treats every tailored variant as a branch off a canonical profile:

Branch & TailorCreate job-specific variants of a single source resume without losing the original

AI TailoringClaude rewrites bullets and summaries against a pasted job description in one click

LinkedIn ImportParse LinkedIn ZIP exports or pull profiles via URL with a Playwright-backed scraper

Document Parsingmammoth and unpdf import existing DOCX and PDF resumes into the structured editor

PDF ExportGenerates ATS-friendly PDFs with deterministic layout

ATS Scoring & Job Aggregation

A scoring engine plus a backend job pipeline so users can score-and-apply in one place:

13-Point ATS ScoringContact info, sections, content quality, formatting. Every check returns explicit, fixable feedback.

Keyword MatchDiff a resume against a target job description and surface missing keywords

Multi-Source CatalogServer-side crons crawl Remotive, RemoteOK, WeWorkRemotely, Himalayas, BuiltIn, Greenhouse, and Lever boards

Personalized MatchEach user sees jobs scored against their own keywords, location, and salary preferences

Kanban TrackerDrag applications through Applied / Phone Screen / Interview / Offer with full status history

Subscriptions & MCP Server

What It Demonstrates

End-to-End Product Ownership

Architecture, billing, infrastructure, support, and growth, all operated as a single-person SaaS

Practical AI Integration

Claude is used in three distinct loops: tailoring, scoring, and agent-driven workflows via MCP

Real Subscription Billing

Stripe webhooks, dedup, retries, partial payments, and three pricing tiers all in production

Job Pipeline at Scale

Continuous crawling of seven job sources, deduped into a single global catalog scored per-user

Key Learnings

Shipping a Real SaaS SoloOwned every layer from product, design, and engineering through billing, customer comms, and infrastructure. The constraint forced sharp prioritization. Every feature has to either retain a paying user or attract a new one.

Building for AI Agents (MCP)Designed PrismCV so the same surface the dashboard talks to is also exposed via Model Context Protocol with 34 typed tools. AI agents in Claude Desktop, Cursor, or Claude Code can run the full job-hunt loop using the same authorization model as the web UI.

Self-Hosting a Paid ProductRuns on a single Hetzner VPS via Coolify: Postgres, Redis cache, MCP server, and the Next.js app on one box, with automated Prisma migrations on every deploy. Trades managed-service convenience for full data ownership and a fixed-cost infrastructure bill.

AI as a Product Surface, Not a DemoThree discrete Claude integrations (tailoring, scoring, agent-driven workflows) each have their own retry logic, prompt versioning, and cost guardrails. The model is a vendor, not a product. The value is in the workflows wrapped around it.
