GovIntel Streamlit UI showing a generated procurement intelligence brief

GovIntel

Overview GovIntel is a local-first federal procurement intelligence system. It imports public USAspending contract awards, stores them in PostgreSQL, builds a Chroma-backed retrieval index, and generates citation-grounded market briefs through a FastAPI API and Streamlit UI. I built GovIntel as a reviewable RAG application with ingestion, indexing, retrieval, analytics, generation, citation checks, Dockerized local setup, CI, tests, and a walkthrough. Links GitHub Repository UI Walkthrough Status GovIntel provides a reviewable end-to-end path: seed contract data, build the retrieval index, run the FastAPI service, open the Streamlit UI, ask a procurement question, and inspect cited award evidence. ...

Abstract BPE token tiles used as the cover for LLM Engineering From Scratch

LLM Engineering From Scratch

Overview LLM Engineering From Scratch is an expanding public lab. The implemented work currently centers on a byte-level BPE tokenizer with deterministic artifacts, stress cases, failure analysis, explanations, and an interactive merge demo. Later model components remain roadmap items. Roadmap inspiration: Ahmad Osman (@TheAhmadOsman) and his article, “Step-By-Step LLM Engineering Projects (2026 Edition)”. The repository uses the article as a roadmap reference; the implementations, experiments, traces, demos, and writeups are independent. Links GitHub Repository Tokenizer From Scratch Blog Post BPE Merge Microscope Demo Status The first project, Tokenizer From Scratch, is implemented with a byte-level BPE tokenizer, deterministic artifacts, and an interactive static demo. The planned sequence continues through embeddings, positional methods, attention, Transformer blocks, training loops, and objectives. ...

Autism Screening Data Dashboard Research

Overview I published this undergraduate applied-ML research on toddler autism-screening data in the International Journal of Information Technology and Computer Science (IJITCS). The work combines dataset analysis, a Tableau/Python dashboard, and a literature review of SVM/CNN classification approaches. I include this project as early published research experience; my current applied-AI engineering case studies are Maintenance-Eye and GovIntel. Publication Published in: International Journal of Information Technology and Computer Science (IJITCS), Vol. 14, No. 4 ...
