About
Passyah Raffi — Senior Full-Stack Engineer & System Architect
I build the systems businesses run on — internal tools, ERP, integrations, and the websites in front of them.
Most projects start the same way: a process that outgrew the spreadsheet holding it together. Chat approvals. Stock that doesn't match. Reports rebuilt by hand. Understanding how the business actually runs comes before any code.
Day to day that happens at LOGO DE CORPS, where I handle the group's website end to end, alongside the digital commerce and internal systems behind several of its fashion brands — LOGO Jeans, Bombboogie, Bodytalk, Ninety Degrees, and FOD.
4+ years across commerce, ERP, and automation — building production systems, not prototypes.

How I approach the work
The process comes before the stack
Tech choices come after the workflow is understood — not before.
Build for the second year
Pleasant in month one, expensive in month eighteen — unless it's built for the long run.
Integrate rather than replace
What already works usually stays. Connecting it beats replacing it.
Make the system explainable
If only one person understands it, that's a risk — not an asset.
How I work
Work starts with your operations, not a tech choice — the stack comes once the problem is clear.
- 01
Business discovery
How the business earns, where it loses time, what to solve first.
- 02
Process mapping
How work actually flows today — including the steps nobody wrote down.
- 03
Solution architecture
What to build, integrate, or leave alone — trade-offs made explicit.
- 04
Development
Built in reviewable increments — working software early, not just at the end.
- 05
Integration
Connected to the tools you already use, so data has one clear path.
- 06
Deployment
Environment, access, and monitoring set up right from day one.
- 07
Continuous improvement
Adjusted as the business changes — the process won't stay still.
Where to go next
Custom ERP & Internal Systems
Internal systems shaped around how your business actually operates — inventory, purchasing, tiered approvals, and operational reporting in one place.
Business Process Automation
Mapping the processes that repeat, then moving them into automated flows so the team spends its time on decisions instead of data entry.
System Integration
Connecting the systems you already run through a structured API layer, so data flows in one clear direction instead of being re-keyed.
Business Website & E-Commerce
Company websites and commerce platforms that load fast, are ready for search, and stay comfortable to build on a year from now.
Shopify Customization
Shopify theme customization and purpose-built tooling for the parts of your operation the platform does not cover.
