Architecture and reliability reviews
For teams working through a Go, AWS, distributed-systems, or SRE decision. Possible deliverables include a written architecture review, a risk and failure-mode register, an explicit capacity or cost model, and prioritized next steps.
There is no one-size-fits-all rate card. Send an async brief with the system, decision, constraints, and desired outcome. You will receive a written scope with deliverables, exclusions, timing, and a fixed fee to approve before any work begins. No automatic recurring charge and no surprise scope expansion.
The initial review does not require production credentials or confidential data. Share only material you are authorized to disclose.
