CTO & AI Systems Architect — typed, auditable Rust AI systems for regulated workflows

CTO at Remolab, building typed, observable, auditable AI systems for regulated workflows — RAG, agents, and LLM orchestration in Rust (Axum, Tokio, Postgres, OpenTelemetry) for fintech and KYC/KYB/AML. Operating thesis: AI prepares, humans validate, audit trails prove. The model can be magical; the system must be boring.

category_theory_transformer_rs

→

An executable, compile-checked book teaching the structure under machine learning — tokens, embeddings, attention, and training modeled as typed transformations in Rust, so ML reads as explicit structure instead of framework magic. Ships runnable examples, exercises, and an open-access mdBook. Co-authored with F. Jafarranmani.

114 stars, 9 forks on GitHub; open-access book at hghalebi.github.io/category_theory_transformer_rs. Its underlying idea reached the Hacker News front page.

rust-ml

→

An open-source course teaching machine learning from first principles in Rust — treating ML as a translation problem from plain English to algebra to Rust newtypes to composable maps. Spans 11 modules from a single neuron to transformers, language modeling, systems, kernels, and inference, with tested companion crates for each stage and a CS336-equivalent Rust track. Live companion site at rust-ml.com.

10 stars, 51 commits; 11 lesson modules each backed by a tested, runnable Rust crate. Live at rust-ml.com.

Work with Hamze

Selected advisory and build work.

Rust + Regulated AI Consulting

Contract

Part timeRemote

Consulting and contract engineering for teams building AI systems in regulated domains — fintech, KYC/KYB/AML. I design and build typed, observable, auditable systems in Rust (Axum, Tokio, Postgres, OpenTelemetry): RAG pipelines, LLM orchestration, and agent workflows where the model prepares, humans validate, and audit trails prove. Available as fractional CTO, architecture review, or scoped project delivery.
