## Introduction
I build systems that help software do more. Eshan Roy (`eshanized`) builds systems software, developer infrastructure, and open-source operating systems.

## Engineering Pipeline
- **Concept**: Define the boundary of the problem worth solving.
- **Architecture**: Structure module hierarchy, data flow, and failure modes.
- **Implementation**: Strict typed interfaces with no perimeter bypasses.
- **Verification**: Clean compiler passes, clean sandbox tests, and cryptographic SHA-256 evidence digests.
- **Release**: Open source with transparent status and comprehensive documentation.

## Flagship Systems
- **M31A**: Autonomous coding-agent runtime with deterministic 11-stage policy gates and atomic SQLite WAL commits (https://m31a.tonmoyinfrastructure.org).
- **Snigdha OS**: Fast, efficient Arch-based Linux operating system distribution and package ecosystem (https://github.com/Snigdha-OS).
- **Octate**: Terminal-native AI code review CLI leveraging Tree-sitter WASM ASTs (https://tonmoyinfrastructure.org/projects/octate).
- **SLMGen**: Practical small language model fine-tuning and evaluation pipelines.
- **MCP SuperAssistant**: Developer tooling for the Model Context Protocol ecosystem.

## Core Philosophy
1. Architecture supports maintainability.
2. Reliability is verified, not asserted.
3. Developer experience is system design.
4. Open source should be useful and understandable.
5. Automation needs boundaries and observability.
6. Performance improvements require measurement.
