01 / SELECTED WORK

Engineering in production

01 / PRODUCTION & ERP

Yazd Tire

Converted machine telemetry into production counts and downtime events using equipment-specific processing rules. Independent .NET calculations and confidence scoring routed reliable records to Rahkaran ERP and uncertain estimates to operators for review.

  • 11 production lines
  • ~75 machines
  • 10,000+ registers / 15 s
How it worked

Most readings flowed from PLCs through industrial gateways into ThingsBoard and PostgreSQL. Some machines used KepServer and OPC UA. The .NET processing layer interpreted each signal in context, from cut counters to curing temperature thresholds.

02 / QUALITY CONTROL

Clever QC

Built a .NET pipeline that read test-station measurements from SQLite and identified compressor and defrost events from power traces. QC specialists could start with detected events and confirm them against the original signals.

  • 408 test stations
  • ~410 units tested / day
  • 21 s sampling
How it worked

The pipeline converted detected events into structured records that could be checked against model-specific quality rules.

More engineering work

Clever Warehouse RTLS

Designed the warehouse, floor and zone model for a four-floor warehouse holding approximately 4,000 refrigerators, linking current locations and movement history to warehouse workflows.

Namakaran Equipment Retrofit

Used current sensing to detect activity on legacy equipment without PLC or Ethernet connectivity and integrated production data with Rahkaran ERP.

Industrial Energy Monitoring

Implemented Modbus current polling and hourly energy aggregation in a software service, with reconnection after communication failures.

CAREER & EXPLORATION

Beyond the featured projects

Meraj Tejarat Atiyeh

Furnace Monitoring & Billet Readiness

Tracked steel billet heating from furnace data and calculated readiness indicators for rolling operations.

.NET, Angular and Rahkaran

Production Order Scheduling

Developed APIs and a multi-equipment interface for recording production order intervals. The form could suggest the next start time from the last interval and supported the Jalali calendar.

Arnatel

E-commerce & Exhibition App

Developed and refactored the Arnamall storefront and took on backend ownership and project coordination in the final months. Built the UI, backend and APIs for an iOS exhibition app in two weeks.

Tejarat Electronic Aval and PayamGostar

B2B Applications & CRM

Built ASP.NET MVC features and database-backed workflows for a B2B platform. Earlier, maintained and debugged a CRM application built with ASP.NET Web Forms.

Research & development

Predictive Maintenance

Explored vibration, sound and voltage patterns as inputs for detecting signs of equipment failure.

Concept design

Mining Fleet Telematics

Developed a concept for loading and dumping status, zone-specific speed monitoring and turn counts as an input to tire wear analysis.

02 / COLLABORATION

What I can help with

  • 01

    Production monitoring

    Extract production counts and downtime events with rules tailored to each machine.

  • 02

    Test-room analytics

    Detect operating cycles from power and temperature traces to guide quality review.

  • 03

    Backend & ERP integration

    Build .NET APIs and connect operational data to enterprise workflows.

01 / INDUSTRIAL TELEMETRYILLUSTRATION

ACQUIRE → INTERPRET → INTEGRATE

From business applications to factory data

I started in CRM, B2B applications and e-commerce, then moved into industrial software at Paivand, a System Group subsidiary. Today I build backend services that collect and interpret equipment data and connect it to production, quality and warehouse workflows.
