Model

showcasing language, vision, and finance models built with care, experimentation, and shipping discipline

Portfolio

SCROLL TO EXPLORE PROJECTS

SHERWIN builds models from scratch, fine-tunes and ships them publicly.

What You’re Seeing
This portfolio collects the projects I am proudest of: a custom GPT-style language model trained on FineWeb-Edu, a Llama 3.1 fine-tune, a class-conditional Fashion-MNIST diffusion model, and a BTC forecasting app.
WHY THIS PORTFOLIO EXISTS
Each project shows a different part of the stack: language modeling, generative vision, and predictive finance. Together they map how I think about training, experimentation, and deployment.

FROM SCRATCH

I designed and trained a GPT-style transformer in PyTorch, including masked self-attention, causal generation, and sampling utilities.

FINE-TUNING

I adapted Llama 3.1 into Dark_Llama_f16 with LoRA and Unsloth, showing efficient model adaptation and release discipline.

GEN VISION

I built a class-conditional diffusion model for Fashion-MNIST, pairing label embeddings with timestep conditioning to generate images from noise.

FORECASTING

I packaged a Bitcoin price prediction workflow into a Streamlit app backed by a saved TensorFlow model, historical BTC-USD data, and multi-day forecasts.

TRAINING PIPELINES

From tokenization to evaluation, I keep the training loop reproducible so experiments can be compared and improved with confidence.

SHIPPING & SHARE

I publish models on Hugging Face and wrap applied projects in interfaces that make the result easy to inspect and use.

Inside the Portfolio
A portfolio of models and experiments across text generation, diffusion, and financial forecasting. Each piece documents a different part of the build process.

Project Questions
The parts people usually ask about
/* Animate Accordion Bottom Grid */
These notes explain the scope of the work, how the models were built, and where each project lives.
  • What is this portfolio?

    It is a model portfolio that brings together my language, vision, and forecasting work in one place.

  • What makes these projects worth showing?

    They cover the full build process: dataset choice, architecture design, training, fine-tuning, evaluation, packaging, and deployment.

  • Where are the models hosted?

    The models are published on Hugging Face, and the BTC predictor is packaged as a Streamlit app for interactive use.
