👋Hi — I’m Patrick Eckler Available for hire

Need something built for your company? A website? An app?

Full‑stack .NET developer who ships ERP‑grade software, real‑time dashboards, and polished web apps.

25+ years of professional experience across ERP and telecommunications. I build robust systems from C, C++, C# to Blazor, .NET, SQL Server, and IIS — the kind of software that survives production and keeps customers happy. Need someone who can own the stack and deliver? I’m your dev.

Industrial Automation C++ (ClearCore) C# HMI TCP/IP AWS

Multi‑Controller Pre‑Roll Automation System

Architected motion control for a 16‑axis production machine using four Teknic ClearCore I/O motion controllers. Wrote targeted C++ routines per controller to drive four steppers each, handling homing, position/speed control, and sensor‑state feedback. Connected all controllers to a Windows HMI via USB (4 COM ports) with a C# app for start/stop, live status, and throughput metrics. The HMI reported telemetry to an AWS‑hosted TCP/IP service for fleet analytics and persisted production data; a companion cloud service pushed usage‑based billing events to StaxBill.

GComm — Private Internal Group Communicator

Company-wide messaging system we use daily across office, shop-floor, and working from home. Runs on a lightweight on-prem TCP/IP service so messages stay inside the LAN/WAN. Windows client supports one-to-one and multi-recipient chats, file and image sharing (snipping-tool paste works great), hyperlinks, status presence, and quick copy/paste workflows. An Android companion app keeps mobile users in sync. Text payloads are encoded in transit; setup is “point clients to the service host and go.”

Transactional Email Pipeline

Designed a templated email system (SMTP on DreamHost) with HTML + plain‑text fallbacks, DKIM/SPF/DMARC‑friendly. Powers receipts, admin notifications, and customer messages.

License Plate Recognition (WIP)

Hybrid C++/C# prototype using OpenCV and ONNX for on‑device plate recognition. Built training pipeline and evaluation harness; integrated with .NET visual tooling.

Legacy Android utilities — self‑published mobile apps (no longer on Play due to policy changes)

If you need mobile sidecars or rugged on‑prem tools, I build and sideload those too.

Tech I Use Daily

If it ships on Windows or the web, I’m comfortable owning it end‑to‑end.
