👋 Hassaan Maqsood here!
I design and build simple, functional systems across software, hardware, and real-world manufacturing.
My work usually lives at the intersection of:
- Reactive architectures (message brokers, schedulers, state pipelines)
- Graph-based editors & domain-specific engines (Web Components, custom parsers, template engines)
- Real-time systems (WebSockets, distributed routers, local-first RAG workflows)
- Practical hardware & fabrication (3D printing, CNC automation, embedded ESP32 systems)
- Product studios & tools that feel like quiet magic — they just work.
I value clarity, honest engineering, and building things.
CNC automation & manufacturing orchestration:
- ESP32 reactive job routers
- Serial managers and machine APIs
- Real-time fabrication job scheduling
Simple ≠ minimal. Simple = functional, clear, and dependable.
Everything I build prioritizes:
- Predictability over cleverness
- Deterministic flows over hidden magic
- Composable primitives over heavy frameworks
- Systems thinking over isolated features
Most of my work starts as a scratch-built engine—designed to scale from a hobby project to a distributed system without changing its shape.
- JavaScript, Python, C++
- Node.js, Web Components, low-level reactive engines
- Real-time systems (WebSocket, pipelines)
- ESP32 firmware (JSON routers, reconnection logic, event pipelines)
- 3D printing (FFF/FDM), CNC, CAD, CAM
- Workshop automation + fabrication workflows
- Distributed message routing
- Custom parsers, schema systems, and DSLs
- Graph-based editors & node/edge UIs
- Reactive Systems Toolkit
- Local-first, graph-powered neutral CAD format (browser-based)
- Local, offline, source-grounded RAG + personal knowledge engine
I’m always open to working with people building:
- Real-time tools
- Local-first apps
- Knowledge systems
- Manufacturing automation
- Complex editors or engines
If it involves clean system design + real-world value, I’m interested.
Build systems that feel invisible — but remove friction for everyone who touches them.
