What it solves
Resume friction for cybersecurity candidates who need more tailored, role-aware application material.
Project Report
Re-Vsion
Re-Vsion is a full-stack resume enhancement platform built for cybersecurity professionals. What started as an AI product idea became a much larger system: marketing site, authenticated app, document pipeline, user-owned data, and production deployment work.
FastAPI + React
JWT authentication
PostgreSQL-backed user data
AI resume workflows
Overview
A product built around a real frustration.
Re-Vsion is aimed at cybersecurity candidates who need more than a generic AI writing tool. The product is designed to help users shape resumes against job descriptions, understand ATS fit, compare improvements, and produce cleaner application material without losing the technical identity of the role they are applying for.
That is what makes the project worth showing properly. It is not just an interface exercise. It touches product positioning, upload and parsing workflows, protected routes, user ownership, output generation, and the question of how much structure an AI tool needs before it starts to feel trustworthy.
What I owned
Product direction, frontend and backend work, auth decisions, data model thinking, and deployment planning.
Why it matters
It shows how I work when a project needs both creative experimentation and practical engineering discipline.
Why I Built It
I wanted to build something more complete than a surface-level AI demo.
A lot of AI projects look interesting for a moment and then stop at the demo stage. Re-Vsion pulled me in because it had room to become a real system. It needed a landing page that explained the value clearly, an application flow that felt coherent, a backend that could manage users and documents, and a security model that made sense for personal files.
That blend suits me. I like projects where experimentation matters, but I also like the point where experimentation has to mature into structure. Re-Vsion became a place to explore AI product ideas while also getting serious about routing, authentication, data isolation, and deployment.
The project says a lot about how I like to build: start with an idea, test it, then keep improving it until the details begin to matter just as much as the concept.
Stack
The stack was chosen to support growth, not just speed.
- Frontend
- React 18, TypeScript, Vite, React Router, Axios, react-dropzone, framer-motion, and HeroUI/Tailwind-related tooling.
- Backend
- FastAPI, SQLAlchemy, Pydantic, Alembic, PyJWT, Argon2-backed password handling, and slowapi for rate limiting.
- Data
- PostgreSQL for multi-user ownership, plus document parsing with pdfplumber, pypdf, and python-docx.
- Ops
- Render deployment target, Docker support, Nginx reverse proxy work, health checks, and request logging.
FastAPI was a sensible fit because it keeps the API layer clean while still giving the project room to grow. React and TypeScript made the app side easier to evolve because there are multiple user states, protected flows, and document-driven interactions that would become awkward in a simpler static setup.
PostgreSQL is also an important part of the story. Once the project moved from single-user experimentation toward a real authenticated product, resource ownership and multi-user isolation became a real requirement rather than a nice extra.
Product Flow
The product needed a clear journey from public trust to private work.
Public entry
The landing page explains the value first so the user understands why the product exists before they are asked to create an account.
Signup and login
Users create an account or log in through dedicated auth routes rather than being dropped straight into the app.
Upload and tailoring
Resume files and job descriptions feed into enhancement flows, style decisions, comparison work, and ATS-oriented feedback.
Protected output
The dashboard, settings, comparison views, and generated outputs sit behind protected routes and user-owned data.
This flow is one of the reasons the project feels substantial. It is not just "upload a file and get a response." There is a proper entry point, a real account system, session handling, and a deeper user journey after authentication.
Security
The security work is part of what makes the product credible.
Re-Vsion handles personal documents, so security choices matter. The repository shows deliberate work around short-lived access tokens, longer-lived refresh tokens, password hashing, protected routes, and user ownership checks.
The project documentation also points to path traversal protection for downloads, PII sanitization in error responses, rate limiting, startup configuration validation, and more careful exception handling. That is exactly the kind of discipline I want my portfolio to show.
- Auth model
- JWT-based authentication with short-lived access tokens and longer-lived refresh tokens.
- Password security
- Argon2-backed password handling and a stronger password policy.
- Data isolation
- User-owned resources and backend ownership checks for protected operations.
- Abuse controls
- Upload rate limiting, validation, and operational checks that support safer deployment.
Architecture
The project holds together because the architecture has clear boundaries.
Frontend layer
Public routes, login and signup pages, protected dashboard routes, and state managed through context and services.
Backend layer
FastAPI routes, typed schemas, utility-driven auth logic, and data operations shaped around ownership and document workflows.
Document layer
Resume files, job information, generated outputs, and parsing logic that tie the product experience to real user inputs.
That separation matters. It means the project can evolve without collapsing into one tangled code path. The public marketing experience, authenticated app experience, backend API logic, and output pipeline each have their own role in the system.
Deployment
It was built with production in mind, not just local success.
One of the best things about Re-Vsion is that it keeps going past local development. The repo includes deployment work for Render, PostgreSQL configuration, Docker support, Nginx reverse proxy planning, health monitoring, and request logging.
That changes the feel of the project. It stops looking like a proof-of-concept and starts looking like something that has been thought through as a hosted product with users, state, and failure modes.
Reflection
This is the project that best represents how I want to grow.
Re-Vsion matters in my portfolio because it brings together the parts of technical work I care about most: creating, experimenting, refining, and then taking the implementation seriously. It is not just visual design, and it is not just backend mechanics. It sits in the middle, where the product has to make sense as a whole.
That is why I want to build more work like this. It matches the direction I am most excited by now: intelligent systems, product-minded engineering, and practical technical work that still leaves room for experimentation.
