I build the strategic tools and frameworks that bridge the gap between Merch, Planning, and Finance. From OTB optimization to algorithmic replenishment, I help global retail brands maximize top-line sales and protect Gross Margin.

The Strategic
Framework.
Four integrated systems. One mission: close the execution gap between Merchandising, Planning, and Finance.
Dynamic OTB & Buy Tools
Managing seasonal and carryover assortments with surgical precision. Custom-built OTB models that account for sell-through velocity, receipt flow, and markdown exposure — giving merchants a single source of truth.
S&OP Inventory Architecture
Real-time inventory health management to identify aged, unproductive products and maintain optimal stock levels. Integrated dashboards that surface the right signal at the right time — before margin erodes.
GM & Markdown Optimization
Strategic markdown planning and channel budgeting designed to protect the bottom line. Scenario modeling that quantifies the true cost of inaction — and the precise levers to pull to recover margin.
Integrated Demand Management
A holistic view of how marketing-driven demand intersects with inventory supply. Closing the loop between the demand generation team and the demand management function — the gap where most retailers bleed.
Purpose-Built Tooling for Global Retail Brands
The Product
Suite.
Purpose-built tools that turn raw data into executable strategy. Each system is designed to surface the signal that drives margin-accretive decisions.
Allocation & Replenishment Engines
Automated core product management systems that eliminate manual guesswork. Rule-based and algorithmic engines that keep shelves optimized and stock flowing to where demand lives.
Channel Budgeting Dashboards
Real-time Gross Margin planning and visibility across all channels. Dynamic dashboards that translate buy decisions into P&L impact — before the purchase order is placed.
Performance Reporting
High-fidelity reporting that connects disparate departments — Merch, Finance, and Marketing — into a single narrative. Executives see the full picture. Decisions get made faster.

Every tool is built to spec for your brand's unique data architecture and reporting needs.

17 Years of
Retail Grit.
Peng Huang
The Architect of Retail Profit
Peng Huang is a Director-level retail executive who has spent 17 years at the intersection of Merchandising, Planning, and Finance — the three functions that determine whether a retail brand wins or bleeds.
His core thesis is simple but rarely executed: demand generation (what Marketing does) and demand management (what Planning does) are two sides of the same coin. When these functions operate in silos, inventory piles up, markdowns accelerate, and margin evaporates. When they're aligned, brands grow with precision.
Peng builds the tools, frameworks, and operating rhythms that make this alignment possible — from dynamic OTB models and algorithmic replenishment engines to integrated S&OP processes that give leadership a real-time view of inventory health across every channel.
His commitment to precision extends beyond the boardroom. As a USA Swimming certified official, Peng brings the same discipline, attention to detail, and standards-driven mindset to every engagement — because in both arenas, fractions of a second and fractions of a margin point are the difference between winning and losing.
"Demand generation and demand management are two sides of the same coin. Most retailers only flip one."

The Challenge
A mid-market specialty apparel brand was carrying 22% excess inventory entering its peak selling season. Seasonal OTB had been built on prior-year receipts with no sell-through velocity adjustment, resulting in a projected $18M markdown liability. The Planning and Merchandising teams were operating from separate spreadsheets with no reconciled view of open commitments.
The Approach
Rebuilt the OTB model from the ground up — introducing a dynamic receipt-pacing framework that tied weekly sell-through to forward buy decisions in real time. Designed a unified Merch-Planning dashboard that surfaced aged inventory by door, class, and vendor. Ran a 6-week markdown scenario model to sequence clearance actions by channel, protecting full-price sell-through on new receipts while liquidating aged units at the highest possible recovery rate.
The Challenge
A fast-scaling omnichannel home goods retailer had no formal S&OP process. Marketing was running demand-generation campaigns with no visibility into inventory positions, repeatedly driving traffic to out-of-stock SKUs. The result: a 34% lost-sales rate on promoted items and a growing disconnect between the CMO and VP of Planning that was escalating to the CEO level.
The Approach
Designed and implemented a full S&OP operating cadence — weekly demand signals, monthly consensus forecasting, and a quarterly strategic review. Built a Marketing-to-Inventory bridge: a live dashboard that mapped planned campaign spend against projected on-hand inventory by SKU, flagging stockout risk 6 weeks in advance. Facilitated cross-functional alignment sessions to establish shared KPIs between the Marketing and Planning functions for the first time.
The Challenge
A premium footwear group with 200+ doors was running allocation on a manual, analyst-driven process that took 3 days per cycle and produced inconsistent results. Core carryover styles — which represented 40% of total revenue — were chronically under-allocated to top-performing doors while excess inventory sat in low-velocity locations. The VP of Planning estimated the misallocation was costing the brand $3–4M annually in lost full-price sales.
The Approach
Designed and built a rules-based allocation engine in Excel/Python that automated core product replenishment using a tiered door-ranking model. The engine incorporated trailing 8-week sell-through, door capacity, and vendor lead time to generate weekly allocation recommendations in under 2 hours. Delivered a parallel performance reporting layer that gave regional managers real-time visibility into door-level inventory health and sell-through pacing.
