Marketing leadership: career records, anonymized cases and the live tools, each labeled for the evidence behind it.
Leadership & decisions
When the channel looked busy, I changed the investment decision. · Career record
I declined to renew a PPC vendor whose reporting did not show persuasive downstream evidence and redirected the money into a bounded, quarter-long experiment.
Channel and vendor allocation authority (~$25K–$50K a month)
Renewal judged on downstream evidence, not channel activity
Setting an Evidence Standard for a PLG Trial Motion · Anonymized case
A free-trial motion needed a way to tell whether a trial conversion represented real progress: whether it could be connected through provisioning, activation, product usage, qualification, sales follow-up, and revenue.
PLG Trial Motion Readiness Diagnostic · Live tool · modeled
Score your free trial motion across five layers: offer, activation, lifecycle, routing, and reporting. Get your primary constraint and prioritized next moves.
Rebuilding demand accountability before scaling activity. · Career record
I rebuilt the enterprise ABM and demand-generation programs and the scoring and lead flow beneath them. SQLs grew 30% and sales pipeline 15% within six months, with no single initiative credited.
Lead scoring and grading rebuilt end to end

Designing a Modular Landing Page System for Trial Conversion · Anonymized case
Trial pages were being built one-off per campaign, which slowed iteration, drove inconsistent messaging, and made conversion learning difficult to compare across waves.
Building a Cross-Functional Demand Operating System · Anonymized case
Campaigns were launching, but ownership, sequencing, and stakeholder visibility were inconsistent. Cross-functional teams were spending too much time renegotiating how work moved instead of executing the work itself.
A control-system simulation of an automated quality cell: explicit machine states, interlocks, fault handling, a simulated E-stop, and recovery that never restarts production on its own.
A browser simulation of control-state behavior only: not a safety PLC, safety-rated control or a certified emergency stop, and not evidence of machinery-safety compliance. Its E-stop is a simulated input to a simulated controller, and nothing here replaces a risk assessment or physical machine validation. AI-assisted tools helped build it. Its tests check the simulation against its documented model, not a physical machine. Neither the simulation nor its tests establish independently demonstrated control-engineering competency on my part.
Controls and interlocks · Simulation · portfolio build
Machine behavior here is determined by explicit state, inputs, interlocks, and controller rules — not by what the interface happens to allow you to click.
The interface never sets an actuator. A button posts a command; the controller evaluates that command against the current state and the interlocks, and only then does an output change. That is why an illegal action produces a stated reason instead of silently doing nothing.
A permissive is a condition that must hold before an action may begin — the checklist at the door. An interlock is a rule that holds throughout, whatever anyone asks for. Start has seven permissives; the conveyor has an interlock that keeps it off while the machine is faulted.
Machine state and process phase are separate concepts. The machine state says what the controller is allowed to do. The process phase says where a part is in the cycle. A cell is RUNNING while it moves through waiting, releasing, transporting, inspecting, sorting and completing — those are not machine states.
The conveyor cannot be commanded while the machine is faulted or E-stopped.
The source cannot release a part unless the machine is Running.
No new part may be released once a controlled stop has begun.
An active fault, a latched E-stop, or any failed permissive prevents a start.
Inspection that is unavailable when it is needed faults the machine; it never defaults a part to pass.
A part cannot be accepted without a completed inspection pass.
A reset requires every blocking cause to be clear, and always ends in Idle.
Fault handling and recovery · Simulation · portfolio build
These change the environment the machine is reacting to, not the rules it follows. That distinction is the point: an operator command asks the controller for something, an injected condition simply becomes true.
Recovery is deliberately unhelpful. Clearing a jam does not restart production. Releasing the simulated E-stop does not restart production. A successful reset always lands in Idle and never in Running, so returning to production is always an explicit operator decision.
Design records and tests · Simulation · portfolio build
Times are controller ticks measured from power-on, not your clock. The same command sequence always produces the same log.
AI-assisted tools contributed to building this project. What it shows are implementation artifacts: the simulation code, its documented control model and its design records. Automated tests and an independent review check that the simulation behaves as that model specifies; they test a simulation, not a physical machine. Neither the implementation nor its passing tests establishes independently demonstrated control-engineering competency on my part.
Project Aegis is a multi-milestone build. This page is M0 and M1: the deterministic control foundation — explicit state, interlocks, faults, recovery, and machine telemetry — and nothing beyond it. The name of the page describes what is actually running, not what the project intends to become.
Later milestones extend the same controller: a richer process model, alarm history and operator authority, production quality analysis, industrial cybersecurity, and a physical prototype with the control model translated toward a PLC.
A constrained diagnostic AI layer belongs to a later milestone too, and it is bounded by design: advisory only, never required for safe machine operation, and never in control of a production-critical output. None of it exists yet, and nothing on this page pretends otherwise.
The broader “secure autonomous” description belongs to the finished system once security and autonomy have actually been built and tested. This milestone has not earned it.
Interests, experiments and two self-reported personal projects outside work, each labeled for what it is, and one engineering case study at the software desk. Apart from that case study, no documentation of a personal project is published yet.

Small tools I build for my own use, with AI-assisted development. They are unpublished experiments: no production use is claimed, and they are not evidence of independently demonstrated coding competency.

Human-directed, AI-assisted: Claude Code agents implemented nearly all of it, and every AI review was a separate Claude session. It is not evidence of software-security credentials, industrial-controls safety competence, or unaided coding.
