# Sepehr Mahmoudian

> Berlin-based AI/ML engineer working across agentic systems, computational
> neuroscience, robotics and 3D software, primarily in Rust and Python. GitHub member since 2014.

## Focus
Agentic systems, computational neuroscience, information theory, neural networks,
robotics, sensor fusion, 3D vision, Gaussian splatting, Rust and Python.

## Selected work
- [engram](https://github.com/sepahead/engram): Engram Neural Modeling Labs is a public placeholder for computational-neuroscience, spiking-network and neural-modeling experiments; its repository says the code will be open-sourced after publication.
- [NCP](https://github.com/sepahead/NCP): NCP is a versioned, project-agnostic canonical-JSON contract connecting neural simulators or neuromorphic controllers to robots, UAVs, simulators and read-only analysis clients. It has a Rust reference, an independent TypeScript validator/client and Python/C/C++ bindings; HEAD is an unreleased, release-blocked 1.0 candidate, while v0.8.0 remains the latest immutable release.
- [prisoma](https://github.com/sepahead/prisoma): Prisoma is a public Rust/Python research toolkit for auditable experiment semantics and intervention-grounded diagnosis of Vision-Language-Action policies, building provenance-complete capture-intervention-replay infrastructure. PID is a conditional diagnostic behind explicit gates; the 0.9.0 release candidate is a source/research preview, not a scientific-results or production release.
- [crebain](https://github.com/sepahead/crebain): CREBAIN (Adaptive Response & Awareness System) is a research-only Tauri prototype for Gaussian-splat scene visualization, simulated cameras, ML object detection, multimodal 3D tracking and ROS/Gazebo drone simulation, built with Tauri 2, React 19 and Rust. The 120 Hz physics and ROS capabilities remain in progress.
- [melkor](https://github.com/sepahead/melkor): Melkor is a C++17 3D Gaussian-splat toolkit for deterministic conversion, inspection, geometry-based scene completion, viewing and explicit external reconstruction pipelines, with CPU/Metal and optional CUDA backends. v2 hardening is in progress; no supported production binary release is available.
- [galadriel](https://github.com/sepahead/galadriel): Galadriel is an experimental safe-Rust cross-sensor consistency monitor for multi-sensor fusion, combining NIS/CUSUM, sign-preserving correlation over producer-attested projections and optional PID diagnostics. v0.9.0 is a pre-1.0 supervisor-review source release; evidence is synthetic/component-level, not field validation.
- [pid-rs](https://github.com/sepahead/pid-rs): pid-rs is a safe-Rust library for shared-exclusions Partial Information Decomposition and mutual-information estimation: categorical SxPID, KSG MI and default-off experimental continuous shared-exclusions/PID surfaces. v0.9.0 is a GitHub-only source-review prerelease.
- [haldir](https://github.com/sepahead/haldir): Haldir Gate is an experimental Rust mission-authorization reference monitor for NCP: it validates signed controller intents, deployment and mission admission, and deterministic policy, then prepares Gate-owned plant commands and signed decision receipts. Its 0.9 review remains NO_GO; it is not production-ready or airworthy.
- [manwe](https://github.com/sepahead/manwe): Manwe is an alpha airspace-perception research and validation workbench spanning vision, audio, multi-camera geometry and multi-target tracking, with a Python numerical/training package and Rust/Candle inference benchmarks. It targets candidate outputs for systems such as Crebain but currently ships no drop-in Crebain adapter.
- [cortexel](https://github.com/sepahead/cortexel): Cortexel is a pre-1.0 TypeScript library and CLI that validates strict declarative JSON requests for neural-simulation figures and renders deterministic, accessible SVG artifacts plus exact-value tables, with fail-closed provenance. v0.9.0 has no stable published package or DOI.
- [relief-atlas](https://github.com/sepahead/relief-atlas): relief-atlas is a Python generation pipeline and 10,079-item corpus of AI-generated GLB meshes for disaster relief, humanitarian aid and civil protection; licensing is recorded per asset.
- [cobot-atlas](https://github.com/sepahead/cobot-atlas): cobot-atlas is a Python generation pipeline for a public MIT dataset of 2,023 unique glTF 2.0 Binary meshes (2,024 GLB files, 33.5 GB) for robot/cobot simulation, manipulation research, VLA training and benchmarking. Hugging Face dataset: https://huggingface.co/datasets/torusprime/cobot-atlas; Dataset DOI: https://doi.org/10.57967/hf/9199; Pipeline DOI: https://doi.org/10.5281/zenodo.20697491.
