I turn operational requirements into usable software, connecting field devices, APIs and interfaces. My foundation is C and Java; I choose the language for the problem and document the decisions behind it.

From the field to the interface — architecture & working principles
Sensors and relays feed PLC / SCADA logic, cloud telemetry and operator interfaces; operator decisions feed back into the process.

| Focus | Work to inspect |
|---|---|
| Electrical commands & process visibility | Circuit exporter · SCADA studio |
| Connected devices & real-time feedback | C17 archive client · Telemetry evidence |
| APIs, security boundaries & data models | Balanced ledger · Inventory API · Concurrent queue |
| Touch-first field interfaces | Android console · iOS inspection store |
| Checkout & operator workflows | Stone POS evidence |
I start with the signal, then the protocol, data model, interface and person using it. Read the signal before writing code; keep operator journeys clear; validate against the real process before shipping.
Leadership: RF Offshore — industrial, offshore and field operations. RF WALLMARKET — autonomous retail, infrastructure and operational technology.
Recorded run · Execution report · Execution index · Project demonstrations
Execution records cover the listed scenarios and source commits. Screenshots below document project interfaces and bench work.
RF Solutions × Stone — POS System
OFS — Offshore Fleet POB Platform
Arduino / ESP32 Telemetry
Device output — ESP32 serial monitor
Python bridge — MQTT messages received
Database — persisted sensor readings
Dashboard — temperature, humidity and inventory
Activity log — inventory movements and recent readings
Workbench & personal projects
Reproduce the recorded execution
Run python .proof/record.py with the prerequisites in the execution index. Scenarios run repository code and check exit codes and expected output. CI publishes the execution-proof artifact with transcripts, input fingerprints and the source commit. The report identifies the tested version; the badge follows the latest workflow run.

GitHub Sponsors · Donate via Stripe · Buy Me a Coffee
Stripe donations do not grant GitHub’s official Public Sponsor achievement. For GitHub sponsor recognition, contribute through GitHub Sponsors and choose public visibility. GitHub controls achievement eligibility and display.
Support helps maintain open tools, troubleshoot issues, publish reproducible examples and documentation, and share new experiments and technical decisions.
Public supporters & sponsor collaboration
Verified sponsors can discuss code reviews, troubleshooting, project guidance and collaboration. Private access instructions are in the GitHub Sponsors welcome message; selected tier terms apply. Buy Me a Coffee uses separate verification. Keep payment details and private project information out of public issues.
Public GitHub supporters are synchronized automatically; private sponsorships stay private.
