Christian Joudon
A software engineer with a designer’s eye and a writer’s ear.
I design and build full stack web applications, AI driven data pipelines, and financial software, then carry them from first sketch to shipped product. Lately I’ve been most interested in one question: how AI can help everyday people and small businesses reach their goals and build lasting financial stability.
The short version
I’m a software engineer who designs and builds full stack web applications, AI driven data pipelines, and financial software, and designs and writes them from concept to finished product. A background in biochemistry taught me to turn messy, real world data into clear decisions. Years of professional creative work taught me to keep the person on the other side of the screen in view.
I design every platform I build, not only the code behind it, and I work comfortably across React, Next.js, Python, PostgreSQL, REST APIs, and LLM powered NLP. I care about user centered design, scalable architecture, and software that is as clear to use as it is to build.
Several fields, one throughline
Engineering, accounting automation, and a long run of creative and operational work. The common thread is building things that make a process simpler for the people inside it.
- Architecting HAVEN, a ledger first trust accounting and reservation management platform, in active agile sprints.
- Built a scalable NLP pipeline that turns unstructured medical notes into structured datasets using large language models, FAISS semantic search, and Apache Spark.
- Developed Chime, a React booking application with Stripe payments; integrated external APIs and shipped responsive production sites end to end.
- Prototyped AI invoice extraction using schema constrained prompts, validation layers, and human review, reaching roughly 87 to 93% structured data accuracy.
- Cut manual data entry time 60 to 75% with automated parsing and validation, and built normalized schemas and secure, mobile first upload portals.
- Feature screenplays, short films, 200+ song lyrics with 20 released on Spotify, and a children’s picture book.
- The creative eye and storytelling instinct that sharpen my product and interface work.
- Property listings, MLS copy, agent bios, and branded digital and print marketing across Zillow, Redfin, and Realtor.com.
- Managed residential real estate developments on budget and schedule, coordinating architects, builders, and designers.
- Front of house operations, training and mentorship, and a recipe cost analysis system that improved profitability.
Ten projects
A mix of production software, data engineering, visualization, and a game. Most are built end to end, design included. Each one opens to a full write up.
HAVEN: Trust Accounting & Reservation Platform
An automation first platform that replaces fragmented accounting and reservation workflows for rental operations.
- A ledger first financial core with strict trust accounting controls and document linked audit trails.
- Bulk reconciliation, payout allocation, and owner distributions on a normalized PostgreSQL model.
Global Events & Market Trends
An interactive system visualizing how wars and pandemics correlate with stock market and GDP trends.
- Geospatial views and real time filtering built with D3.js, Plotly.js, and Observable.
- Explorable correlations across regions and event types.
COVID-19 Records: NLP Pipeline
A scalable pipeline turning unstructured medical notes into clean, structured datasets for analysis.
- LLM driven extraction with Pydantic validation, and FAISS for semantic medication matching.
- Apache Spark analytics on comorbidities, medication frequencies, and demographics.
Chime: Booking Widget
A responsive React booking widget with fluid, zero reflow transitions, built for a clean handoff to backend services.
- State driven service, calendar, and booking views with Framer Motion sliding panes.
- Color coded availability heatmap; Stripe checkout integrated.
UHnify: Campus Engagement
A student club platform for browsing clubs, managing memberships, and tracking events in real time.

Automated Refund Draft Builder
An internal tool that generates guest specific refund emails with the correct PDF attachments.
- Gmail and Drive APIs with recipient and attachment mapping.
- Validation safeguards and branded HTML formatting.
Languages and systems
Where the foundation came from
Screenplays, songs, and a book
The other half of my work. It is where the design instinct and the habit of writing for an audience come from.
200+ original song lyrics, with 20 released on Spotify.
Writing on the work
Reflections and technical pieces on software engineering, AI, design, and a few ideas I keep returning to.
