SPACE TECH 7 / ENGINEERING NOTES

Engineering notes for systems that have to work.

Original SpaceTech7 writing on private AI, product architecture, autonomy, mission software, and financial operations. Each note is made for the person who has to design, approve, build, or run the system.

Discuss an engineering question

Read the engineering notes.

Practical notes for product teams, technical founders, and the people who operate software. Start with a question, then connect it to the engineering work behind it.

01

Private AI

What a company LLM needs before it becomes useful at work

Architecture notes on knowledge boundaries, retrieval quality, permissions, evaluation, and the human decisions that should stay visible.

  1. Where should model access stop?
  2. How should a user inspect the source?
  3. Which actions require approval?

02

Product engineering

Choosing the smallest product architecture that can survive success

A practical look at account models, integrations, analytics, operations, and the technical decisions that become expensive to reverse.

  1. What belongs in the first release?
  2. Which boundaries need to be stable?
  3. What can remain manual?

03

Autonomous systems

Designing the moment when a machine asks a person for help

Interface patterns for system state, uncertainty, alerts, interventions, and the record left after a human takes control.

  1. What state matters now?
  2. Why did the system stop?
  3. What should the operator do next?

04

Mission software

Turning telemetry into a decision surface

How mission software can connect live data, plans, procedures, anomalies, and team handovers without burying the important signal.

  1. Which signal changes the plan?
  2. Who owns the next decision?
  3. How is the decision recorded?
