I build manufacturing-grade ERP/CRM workflows that reduce operational friction and make data reliable — without turning teams into “software operators”.

Core delivery themes

• Quote-to-Cash (Q2C): pricing rules → quote versioning → approvals → order handoff → invoicing alignment
• Procure-to-Pay (P2P): requisitions → RFQs → supplier comparison → approvals → PO → GRN → invoice matching
• Inventory Accuracy: traceability, controlled adjustments, cycle counting programs, multi-warehouse transfers
• CRM ↔ ERP Integration: stable contracts, idempotency, retries, audit trail, observability
• API-first Architecture: REST/Webhooks for accounting, logistics, marketplaces, and internal systems

Typical outcomes

• Faster approvals, fewer “stuck” purchase cycles
• Higher stock accuracy & traceability (who/when/why)
• Integrations that don’t break every month
• Dashboards that drive actions (not vanity metrics)

Note: The details below are generalized to protect client confidentiality.

A manufacturing/distribution team ran critical workflows across spreadsheets + disconnected tools:

• RFQs and supplier comparisons in email threads
• Inventory adjustments without clear reasons or approvals
• Pricing exceptions handled manually (margin leakage)
• Integrations failing silently (rework + delayed deliveries)

• Workflow audit (current-state map + bottleneck list + quick-win plan)
• Implemented governed workflows (roles, approvals, exception handling, audit trails)
• Built API-first integrations (idempotency, retries, structured logging, alerts)
• Introduced data governance rules for master data + change history
• Added operational dashboards (cycle time, variance signals, compliance metrics)

• Procurement cycle time reduced by removing manual handoffs and approval chasing
• Inventory variance became traceable (who/when/why) with controlled adjustments
• Pricing exceptions moved to governed approvals, improving margin control
• Integrations stabilized with monitoring and replay-safe delivery

• Clear ownership per workflow step (business + IT)
• Smaller set of non-negotiable rules (instead of “more features”)
• Reliable integrations treated as production infrastructure

1) Workflow Audit (fast, high-leverage)

• Current-state mapping (systems + exceptions)
• Bottleneck diagnosis (approvals, data, handoffs)
• A 1-page architecture & quick-win plan you can implement

2) Build & Integrate (production delivery)

• Clean domain model + role-based permissions
• Workflow automation + audit trail
• API contracts + monitoring + replay strategy

3) Stabilize & Scale

• KPI instrumentation, governance rules, optimization
• Performance & reliability hardening

If you want this profile to convert better, pin a few small but polished repos:

• erp-workflow-templates (approvals, audit trails, exceptions)
• integration-governance-playbook (idempotency, retries, webhooks)
• rfq-po-grn-sample (mini domain model + API contract)
• geo-dashboards-demo (map + heatmap + route sample)

I apply GIS & cartography where location drives operations:

• Multi-site / multi-warehouse planning (coverage, zones, territories)
• Route & dispatch logic for field service / deliveries
• Location master data strategy (geo-normalization, deduplication, governance)
• Analytics: region performance, SLA heatmaps, distribution footprints

• Anadolu University — Geographic Information Science & Cartography (Associate Degree, in progress)
• Istanbul University — Computer Programming (Associate Degree, in progress)
