Timothy Nduati — Engineering systems where software meets the real world

Software Engineer · Aviation Technology · Data Platforms · AI Infrastructure

I build software for complex aviation environments and explore the systems behind data, markets, and intelligent developer tools.

Portfolio · GitHub projects · LinkedIn · X


Selected work

Project Engineering focus
Nexus Model-agnostic AI harness: agents, tools, permissions, worktrees and orchestration
Aviation Intelligence Evidence-grounded aviation document intelligence and decision-support tooling
Market Data Infrastructure Data ingestion, normalization, time-series storage, and low-latency APIs
Warehouse Neuron Event-driven inventory workflows with FastAPI, Redis Streams and Flutter

Area Technologies
Languages Python · TypeScript · C# · SQL · Rust · Go
Data PostgreSQL · Kafka · Redis · Spark · Airflow
Platforms Linux · NixOS · Docker · CI/CD · Git
Software .NET · Angular · APIs · event-driven systems · agent runtimes
What I'm exploring
  • Aviation technology — reliable software, regulatory workflows, provenance, and interoperability.
  • Data and finance — market-data infrastructure, analytics, stream processing, and systems reliability.
  • AI infrastructure — model-agnostic tools, grounded retrieval, orchestration, and developer experience.

My open-source aviation work is independent of my employer's projects. No client or proprietary implementation details are shared here.

Engineering principles

```text observe → understand → design → build → measure → evolve ```

Build more than you consume. Understand a system before optimizing it. Keep the architecture understandable.
