Understand
Map the process, the data, the people, and the way the work actually flows.

Turning complexity into clarity.
I help businesses untangle complex processes, clean up their data, and build systems that eliminate manual work and support how work actually gets done.

PROCESS FIRST
I came from real processes, not from code.
For more than 11 years, I've worked inside real business and manufacturing operations—where an order moves from the customer to the system, production, data, and reporting.
I've seen how ERP, MES, CRM, Excel, reports, and people interact—not on a diagram, but in day-to-day work. Where delays happen. Where data gets duplicated. Where the status in the system doesn't match what's actually happening.
That's why automation, for me, doesn't start with choosing a technology. It starts with understanding how the process really works—and where it breaks.

HOW I WORK
Understand first. Automate second.
I don't start with a tool. I start with one question: what's actually happening here?
02
Ask "why?"
Find unnecessary steps, duplication, dependencies, and weak points.
WHY THIS WAY?
03
Simplify
Remove what isn't needed and keep only the logic that adds value.
WHAT CAN WE REMOVE?
04
Automate
Only then build a system that runs reliably.
NOW WE BUILD.
PROCESS
Less complexity.
Fewer manual steps.
More control.

EXPERIENCE MAP
Not a collection of tools. One connected system of experience.
My experience sits at the intersection of business processes, manufacturing, data, systems, and the people who use them.

Integrator
of processes
business ↔ systems
Business processes
Rules, logic, roles, and real-world workflows.
Manufacturing
Orders, execution, status tracking, and production operations.
ERP / MES
Business data and end-to-end process control.
CRM
Customers, activities, interactions, and data.
Excel / Power Query
Data prep, cleanup, logic, and modeling.
Power BI
KPIs, analytics, models, and reporting.
Testing / UAT
Scenarios, defects, retesting, and system behavior.
Data migration
Cleansing, mapping, validation, and reconciliation.

HOW I THINK
Automation doesn't start with automation.
There are a few principles I check in almost every process before any technical build begins.
If data is entered twice, sooner or later it won't match.
Automation doesn't fix a bad process. It just makes the problems happen faster.
A dashboard can't fix bad or unreliable data.
If only one person understands the system, that's a dependency—not a system.
Exceptions need to be designed alongside the standard workflow.
If users hate the system, being technically correct isn't enough.
THE QUESTION THAT MATTERS
Does this make the process simpler,
more reliable, and easier to understand?

HANDS-ON EXPERIENCE
Not just analyze it. Get it working.
I've worked on problems at the intersection of operations, enterprise systems, data, testing, reporting, and automation.
01
MANUFACTURING OPERATIONS
ERP / MES and order flow
Working with order statuses, business rules, end-to-end scenarios, and actual system behavior.
02
DATA
Data prep, cleansing, and reconciliation
Data cleansing, mapping, validation, migration prep, and result checks.
03
TESTING
Test scenarios, defects, and UAT
Reproducing defects, documenting evidence, verifying fixes, retesting, and supporting user acceptance testing.
04
ANALYTICS
KPIs, models, and reporting
Preparing data for analysis, building models, metrics, reports, and analytical dashboards.
05
AUTOMATION
Manual work → repeatable logic
Automating repetitive operations, data processing, checks, reporting, and workflows.
06
INTEGRATIONS
CRM, systems, and operational data
Working with integration scenarios, data exchange logic, CRM behavior, and system-to-system interactions.
FROM PROBLEM TO OUTCOME
Understand → validate → simplify
→ build → test
07
EXPERIENCE TIMELINE
The tools changed. The approach became more systematic.
From my first steps in Excel to data models, enterprise systems, analytics, and my own automation projects.

HAVE A PROCESS THAT SHOULD BE EASIER?
Let's remove the unnecessary complexity.
Show me how the process works today. I'll help identify what can be simplified, automated, or made more reliable.
