Core Engineering Innovations

Fuzzy Address Normalization: Built a parser solving unstructured Thai shipping strings into standardized Province & Amphoe IDs with bilingual support (TH/EN/ZH).
D3-Geo Vector Projection: Designed a custom SVG coordinate projection supporting fluid zoom, pan, hover tooltips, and quantile heat scales without lag.
Geo-Fencing Ad Precision: Pinpointed high-AOV clusters (Bangkok, Chiang Mai, Chonburi) and excluded low-ROI zones in TikTok Ads Manager to maximize margin.

Architectural Artifacts 3 Key Modules

Artifact 01

77-Province National Choropleth Heatmap

D3-Geo Vector

Tap to expand

What it shows: Macro spatial heatmap calculating regional revenue shares, customer volume, and order density across all 77 Thai provinces.

What this proves: Demonstrates mastery of D3-geo SVG projections, quantile scale algorithms, and real-time client-side interactive rendering without performance degradation.

Artifact 02

District-Level (Amphoe) Deep Drill-Down

Micro-Targeting

Tap to expand

What it shows: Secondary modal zooming into individual amphoes, correlating postal codes with product category affinities (e.g. Reed Diffusers vs. Essential Oils).

What this proves: Proves capability in architecting complex hierarchical interfaces and translating micro-geographic patterns into targeted SKU marketing.

Artifact 03

Fuzzy Address Normalization Pipeline

Data Pipeline

Bangkok Dist: Watthana Region: Central Code: 10 ✓ Ready for D3

Tap to expand

What it shows: Robust multi-stage ingestion parsing messy addresses, abbreviations (e.g. กทม.), and postal codes into standardized geographic relational schema.

What this proves: Demonstrates practical data engineering rigor and algorithmic problem solving under real-world marketplace data imperfections.

Executive Strategic Takeaway

“By elevating raw e-commerce logistics data into interactive geospatial intelligence, we replaced nationwide spray-and-pray advertising with targeted regional ad bidding—cutting wasted ad spend while accelerating delivery turnaround in prime buying corridors.”
