Software & systems engineer — industrial IoT, real-time telemetry and offline-first systems
Caracas, Venezuela · Remote, hours overlapping the Americas
I build the software industrial operations depend on: real-time telemetry, networked hardware control, and systems that keep working when the network does not. Five years, four production systems, ~3,000 commits — shipped alongside my Computer Science degree, not after it.
| Result | What it means | Where |
|---|---|---|
200–500 ms → 1–10 ms |
Replaced HTTP polling with a full-duplex WebSocket architecture; the server pushes state changes instead of the client re-asking for data that has not changed. Bandwidth down up to 95%. |
Industrial Digital Twin |
524 of 681 commits |
Principal author and architect over five years, 398 files, version 12 in real field use. |
IoT hardware control |
100% offline |
Plant floor runs with no internet and reconciles bidirectionally when connectivity returns. Zero field work lost. | Offline-first ecosystem |
20/20 + mention |
Undergraduate thesis graded maximum with a Publication Mention, University of Zulia. | Video stabilization |
Note
The four industrial systems are private client repositories under NDA. I describe architecture, decisions and trade-offs — never business data. Happy to walk through any of them on a call.
Industrial IoT hardware control — operates inspection cameras from two networked machines, unattended in the field · 2022–2026
Desktop application that coordinates industrial inspection cameras across two machines with no technical support present on site.
- Dual-PC architecture — the same executable relaunches itself and assumes its role, server or client, with zero manual setup by the operator.
- Resilient transfer — chunked image transfer with reassembly and connection-drop handling.
- No dead UI — explicit timeouts at every network boundary, so a powered-off camera never freezes the interface.
- Refactored under delivery — monolith to modular library without stopping shipping, with a pytest/pytest-qt suite and a versioned Windows installer.

Offline-first ecosystem — 100% offline on plant floors, bidirectional cloud sync · 2023–2026
Desktop client that operates with no connectivity and reconciles with the cloud once the network returns.
- Sync that survives the field — per-endpoint sync state, connectivity detection and retries.
- Self-contained delivery — a Python orchestrator brings up a portable database, Node/TypeScript services and the API, packaged in an installer that resolves its own dependencies.
- Applied AI in-product — custom audio transcription and synthesis pipeline (FastAPI/Uvicorn).
- CI/CD — GitHub Actions, tests with configuration isolation and connection pooling.

Industrial time-series analysis — detects thermal cycles, replaced manual spreadsheet work · 2024–2026
Finds thermal cycles and gradient key points in sensor series.
- Detection that does not break — peak and valley detection with SciPy over a smoothed signal, plus interpolation of faulty readings.
- Format-change resilient — Polars pipeline adapted to two source-format changes without a rewrite.
- Engineering-ready outputs — structured JSON per cycle, an Excel table and an annotated plot.
