Mindset & Philosophy

How I approach problems

It's not a coincidence that a C# engineer can design quality inspection flows for jewelry or compressive strength standards for cement.

Architecture first, code second

Never write the first line of code without understanding the bounded context, data flow and trade-offs. Documentation and design diagrams are investments, not waste.

Domain knowledge is the edge

Deep domain understanding is a competitive edge — from the LSF coefficient in cement clinker to the Peel Test in athletic footwear. Better code starts with truly understanding the problem.

Ambitious, but pragmatic

Building a multi-industry ERP/MES with a small team — not because of recklessness, but choosing the right tool: Modular Monolith first, Kafka when needed, K8s only when scale truly demands it.

Build for real people

Factory operators use tablets on the shop floor. Customers want data on-site, not in the cloud. Technology must serve people — not the other way around.

AI-Augmented Development

Early adopter of AI agents and LLM-assisted workflows — using them not just for code generation, but to automate analysis, planning and cross-domain reasoning in manufacturing software.

Flagship Project

ERP/MES Industry Platform

A multi-industry manufacturing platform — one command to bootstrap industry-standard data for any sector.

In Development .NET C# 9 Personal Project Manufacturing · ISA-95

ERP/MES — Composable Architecture

An independent personal project — not affiliated with any employer — distilled from 8+ years of hands-on manufacturing ERP experience. Built on ISA-95 with Clean Architecture + DDD + CQRS + Event Sourcing. One-command industry bootstrap seeds roles, workflows, KPIs and quality templates across Jewelry, Cement, Steel and Footwear.

Industry Seed Engine

4 industries · ~180 records each · 1-command bootstrap (incl. calibration schedules + ECO templates)

Event Sourcing

Full audit trail, reconstitution from events. Meets ISO/IATF traceability requirements.

Event-Driven + Outbox

Kafka + Transactional Outbox → 15 topics across all BCs — Projection updates Read Model in real-time.

Domain Tested

266 unit + 12 architecture + 7 integration tests — business rules, OEE formulas, layer boundaries and API smoke coverage.

Docker Ready

Multi-stage Dockerfile · prod + staging compose + nginx reverse proxy + SSH deploy via GitHub Actions CI/CD.

ASP.NET Minimal API

190+ REST endpoints across 22 modules · JWT refresh rotation · Rate limiting · SignalR realtime · Scalar · Health checks.

Predictive Analytics + Sensor OEE

Rule-based equipment health scoring · inventory days-to-stockout · quality risk. Sensor telemetry ingest → absolute A×P×Q OEE from machine data.
