20 automation projects demonstrating how to turn messy supply chain data into decisions that move KPIs.
Powering Data Driven Supply Chains
Building robust, scalable analytics and automation solutions that reduce costs, improve visibility, and streamline your operations.
Live Analytics Portfolio
20 functional supply chain tools real datasets, AI forecasting, interactive dashboards and raw data downloads.
Data and scenarios use public datasets or altered figures for demonstration. All tools are fully functional.
Projects on this site are built on public or simulated datasets to demonstrate methodology. Metric figures are illustrative of tool capability, not outcomes delivered at a company. Happy to walk through the logic of any project.
Port congestion and transit delays cause reactive, costly disruptions with no early warning system. Companies only discover delays after goods are already stuck.

surfaces hidden freight cost (~€180K on sample data) Detects carrier overpayment patterns across multiple lanes
Manual reorder point calculation leads to delayed purchase orders and frequent stockouts. Static reorder points don't adjust to changing demand or lead time.
▶ SOLUTIONExcel model with dynamic reorder point formulas, colour coded alert list, and draft PO generation using Z score safety stock logic.
full elimination of manual reorder tracking 100% automated reorder triggers for 200+ SKUs
Purchasing teams have no historical visibility into supplier lead time accuracy. Promised lead times in contracts often differ from actual performance.
▶ SOLUTIONSQL tracker comparing promised vs actual lead time per supplier, calculating reliability scores and flagging >20% variance for review.
up to 25% on time delivery improvement Identifies top chronic late suppliers for performance management
EU CSRD regulations require Scope 3 emissions reporting, but emissions data is fragmented across carriers and not calculated consistently.
▶ SOLUTIONPython tool calculating per shipment CO₂e using GLEC Framework. Includes modal shift scenario comparison (road vs rail vs air).
Scope 3 emissions quantification across 8 logistics lanes ESG ready reporting structure
Companies manage inventory metrics in isolation with no visibility into whether turnover ratios are competitive versus industry benchmarks.
▶ SOLUTIONPower BI model comparing inventory turnover, DIO, dead stock %, and GMROI against sector benchmarks with RAG status.
surfaces trapped working capital (~€2.1M on sample data) ITR benchmarking across 4 industry sectors
Traditional monthly forecasting misses sudden demand signals from market events, competitor promotions, or weather patterns.
▶ SOLUTIONAI agent monitoring daily POS data with Python anomaly detection identifying deviations >2σ from rolling baseline and triggering alerts.
detects demand shifts 2 weeks early 38% MAPE improvement over statistical baseline on sample data
Procurement teams deliver savings but struggle to quantify and present them in a consistent, finance approved format. Without a tracker, claims lack credibility.
▶ SOLUTIONExcel tracker categorising savings by type with finance sign off columns. Outputs executive ready waterfall chart and monthly pipeline report.
annual savings tracking (~€2.3M on sample data) 80% hard savings verification logic with Finance sign off workflow
Multi depot distribution networks are rarely re evaluated. Depot locations established years ago may now be generating excess transport cost.

up to 22% distribution cost reduction DC closure scenario with €1.4M/yr savings modeled via LP
Food and pharma companies lose millions to write offs due to poor batch visibility. FEFO picking is not consistently enforced across locations.
▶ SOLUTIONSQL system pulling batch expiry data from WMS, generating risk tiers and recommending redistribution or markdown actions.
prevents product write offs (~€380K on sample data) FEFO compliance improvement up to 55%
Companies invest in demand planning but never measure forecast accuracy systematically. Planners repeat the same systematic biases each cycle.
▶ SOLUTIONPower BI scorecard tracking MAPE, forecast bias, and tracking signal by product family, planner, and customer with drill down capability.
up to 30% forecast error reduction Planner level bias decomposition across planning teams
Purchase orders are tracked in ERP but data is never surfaced into actionable analytics. PO cycle time, compliance, and spend concentration are invisible.

Read Case Study →About Me
I don't just analyse supply chains I build tools that fix them. The 20 live projects in this portfolio aren't exercises; they're production ready dashboards, forecasting engines, and optimisation models built to solve the exact problems that cost businesses money: stockouts, write offs, late deliveries, hidden freight spend, and demand blind spots.
What makes me different is the combination of real floor level operations experience and modern analytics capability. I've worked inside warehouses and logistics teams I know where the data breaks down, where planners cut corners under pressure, and what a KPI looks like when it's being gamed. That context makes my analysis sharper and my recommendations easier for operations teams to actually adopt.
Give me a dataset, a broken process, or an unanswered business question and I'll return a structured solution, a working dashboard, and a clear path to measurable improvement. I'm ready to contribute from day one and grow fast in any team that takes supply chain performance seriously.
Work ExperienceWhat They Say
Feedback from colleagues, supervisors, and academic mentors who've seen the work first hand.
"Chibuike demonstrated a strong ability to connect operational practice with rigorous analytical thinking. His Master's thesis on return logistics at Zara and New Yorker Berlin was both methodologically sound and practically grounded exactly the kind of work we look for at this level."
"Chibuike helped me build a set of financial and operational dashboards that genuinely changed how I work at Pentixapharm AG. Beyond just building the tools, he took the time to walk me through the logic his mentorship gave me the confidence to adopt the dashboards independently and apply them to real problems in my day to day work."
