About Me
I'm a data scientist and AI practitioner who builds tools that solve real problems — like RepoDeck, a SaaS platform I built from the ground up. Whether I'm writing code, building models, or architecting cloud infrastructure, I bring the same analytical mindset and commitment to quality.
My unique edge? I don't just build data models — I use them to solve real problems. Every line of code I write is informed by real-world experience.
Skills & Expertise
What I Do
Machine learning, data engineering, and the product work that ships them — one analytical approach end to end.
AI & ML Engineering
Models that make it to production
From LLM-powered features to classic ML — I design, evaluate, and ship models as reliable product features.
- LLM apps & AI product features
- Model training, evaluation & monitoring
- Python, TensorFlow, PyTorch
Data Science & Engineering
From raw data to decisions
A decade of building data pipelines, analytics, and predictive models that turn messy data into answers.
- ETL & data pipeline architecture
- Statistical analysis & predictive modeling
- SQL, Pandas, scikit-learn
AI Product Development
Full-stack, end to end
I take AI products from idea to deployed SaaS — like RepoDeck, built and shipped from the ground up.
- React, Next.js, Node.js
- Cloud architecture (AWS / GCP)
- RepoDeck — production field-service SaaS
What I Build
Real products solving real problems — not toy projects.
RepoDeck — Field Service SaaS Platform
A SaaS platform that streamlines field-service workflows with AI-assisted reporting — voice dictation, streaming report drafts, and professional PDF generation. Built end to end: Next.js web, Flutter mobile, Python services.
Personal Portfolio Hub
This website — Next.js 15 App Router with a streaming Gemini-powered assistant, a Supabase-backed admin CMS, and server-rendered SEO.
AI / Data Science Projects
A collection of machine learning and data science work including predictive models, NLP applications, and computer vision experiments. Explore the repositories on GitHub.
Writing & Teaching
Thousands of people learned ML from my Kaggle notebooks. I document what I build — it's how I learned, and how I give back.
