AI Developer | Automation & Predictive Analytics
I build AI systems that take repetitive work off your plate and turn your data into decisions you can act on. Over 5+ years I've automated workflows that ran for hours down to minutes, shipped computer-vision models north of 97.5% accuracy in production, and built specialized models that outperform frontier LLMs on-task at a tiny fraction of the compute.
AUTOMATION
I design pipelines and AI-driven workflows that replace manual, error-prone processes: LLM-powered document processing, data ingestion and ETL, RAG/MCP integrations, and agentic systems that handle the busywork. I've cut enough of it for clients to gain multiples worth of efficiency gains.
PREDICTIVE ANALYTICS
I build forecasting, classification, and risk/scoring models that turn historical data into reliable signal - with the feature engineering, evaluation, and monitoring to keep them accurate in production, not just in a notebook.
I also handle the engineering around the models - infrastructure, security, and the supporting services that keep everything running in production. When a project calls for it, I work across NLP, computer vision, and custom model training/fine-tuning.
SELECTED RESULTS
- Automated document processing from hours to minutes with LLMs
- 97.5%+ accuracy on production computer-vision inference
- Fine-tuned a compact language model to more than 5x the on-task accuracy of a frontier LLM (GPT-5.5) while using thousands of times less compute
CORE SKILLS
- Predictive analytics & forecasting, machine learning, deep learning, LLMs, computer vision
- Workflow & data automation, MLOps, custom model training, optimization & fine-tuning
- Supervised, unsupervised (K-Means, HDBSCAN), and reinforcement learning (Stable-Baselines3)
STACK
- Languages: Python, SQL, Bash
- ML/Data: scikit-learn, PyTorch, TensorFlow, XGBoost/LightGBM/CatBoost, pandas
- Build & Deploy: FastAPI/Flask, Docker, Kubernetes, Git
I care about modular, efficient systems that keep working long after handoff - not one-off scripts that break the moment requirements shift. If you've got a process worth automating or data worth predicting from, let's talk about moving your project forward.

Hey, I'm DJ, a web developer and graphic designer with 4 years of experience building polished, high-performing sites and visuals that actually convert.
My sweet spot is Wix, specifically Studio, Velo (custom code & APIs), and eCommerce. I've built everything from service business sites to online stores with custom integrations, and I know the platform deeply enough to push it well past its defaults. If you've hit a wall with what Wix "can't do," that's usually where I come in.
On the design side, I bring a developer's eye to every project, so my work isn't just pretty, it's built to perform. I do UI/UX design, social media graphics, print collateral (flyers, business cards, brochures), and logo refinements for brands that need a polish-up rather than a full rebrand.
🎨 Design & Web Highlights
Wix Studio + Velo: Custom-coded dynamic pages, third-party API integrations, and eCommerce builds that go beyond drag-and-drop
UI/UX: Designed and developed a full-stack CRM interface with real-time dashboards, boosted client productivity by 75%
Brand & Print: Social graphics, flyers, and brand collateral for small businesses and launches
Logo Refinements: Modernizing, vectorizing, and sharpening existing logos, not starting from scratch, but making what you have work harder
✅ What I Do Best
Wix: Studio, Velo, eCommerce, app integrations
Graphic Design: Social media, print, UI/UX, brand touch-ups
Web Dev when needed: React, Next.js, Node.js for when Wix isn't the right tool
Clean, fast delivery
🛠 Tools
Wix Studio · Velo · Adobe Illustrator · Figma · JavaScript · React · Next.js · Node.js · MySQL · Git
