Bakersfield, California · Software architect
I'm Nathan Mayer, a software architect and independent builder. My work has included artificial-lift analytics at Theta, payment systems at Amazon, and grant and healthcare claims workflows through Linean.
Today I run KitFox Labs, my independent software practice.
A working perspective
Understand the process.
Respect the records.
Make the next step clear.
I'm interested in useful Central Valley projects, especially where people work around disconnected data, old software or rules that are hard to get right.
Let's connect01 / Selected experience
Equipment, payments, applications and claims. Different domains, with a shared need for careful software and understandable records.
Theta Oilfield Services, Inc.
I built pump-analysis and telemetry software at Theta, progressing from Full Stack Software Developer to lead development roles in Artificial Lift, XSPOC and Data Science.
My starting question: how can data help someone understand what needs attention?
Amazon
As a Software Development Engineer, I worked on payment systems at Amazon in August 2020–May 2021 and February 2022–September 2025.
My starting question: what happens to the record when a process fails or needs a person to intervene?
California state agency · through Linean
I contributed to grant-management software for a California state agency through Linean.
My starting question: can people see what needs a decision and what happened to an application?
Grant workflow notesSchool-agency work · through Linean
I worked on school-agency healthcare claims workflows through Linean.
My starting question: who can act on a record, and how will someone explain a change later?
Claims workflow notes02 / Career
Software engineering since 2016. KitFox is my current practice; the roles below are my professional history.

Bakersfield
Jan–Oct 2016
I built multiphase-flow analysis for electric submersible pumps.
Oct 2016–Sep 2017
I led development of gas-lift and electric-submersible-pump analysis software.
Sep 2017–Oct 2018
I led development of XSPOC well-monitoring software and designed tools to analyze artificial-lift equipment failures.
Nov 2018–Aug 2020
I developed anomaly-detection and classification software for pump telemetry and worked on exception-based monitoring in XSPOC.
03 / Exploring
Research and experiments, alongside my established software work.
I've explored double-entry water-accounting prototypes. I'm interested in water records, reconciliation and reporting, and in understanding the accounting work with the people responsible for it.
Where do records disagree, and what does it take to resolve the difference?
Talk water workflowsI want to test whether AI can help people gather evidence or explain an exception. A useful test has authorized examples, a comparison with the current process and human review.
Does it help someone make a better decision, and can they check its work?
Compare notes on AI04 / Working together
A software problem, a local project, a technical review or an opportunity to contribute. For paid work through KitFox, these are three bounded starting points.
These are proposed first scopes. We agree scope, access, acceptance criteria and schedule before starting. Larger implementations are scoped separately.
For a business owner, operations director or technical lead.
A rewrite, migration or hosting decision is unclear because the system is expensive, fragile or hard to understand.
For an agency or program manager, billing lead or operations team.
People re-enter information, approvals stall or ownership of the next step is unclear.
For an operations or technical lead with an existing task or exception queue.
People spend time gathering evidence or explaining exceptions; the value of AI is uncertain.
Paid project scope starts through KitFox. Email [email protected] with the system or process you use today and the decision or change you need.
