Hi,I'm Phuc Anh Le.
Lê Phúc Anh (LPA / Phuc Anh Le) — Fullstack & Data Engineer portfolio tại lpa.io.vn. Founder Biterra, chuyên xây dựng hệ thống web hiệu năng cao, kiến trúc dữ liệu và giải pháp AI tại Việt Nam.
Crafting scalable code that works harder than your morning coffee.
01 / About
A builder who ships.
I'm Phúc Anh (LPA) — a Fullstack & Data Engineer based in Vietnam. I design and build systems from database schemas to deployment pipelines. Currently the founder of Biterra. I believe the best code is code that solves real problems, documented well enough for someone else to maintain.

Featured Systems.
High-performance solutions engineered for scalability and measurable impact.
vn-xaphuong-2025
A nationwide administrative data system standardizing Vietnam’s 2025 boundary changes. Shipped as an enterprise-grade NPM package and REST API.
Vietnam's 2025 administrative restructuring changed thousands of boundaries, breaking address validation workflows for businesses.
Built a structured geographical boundary model mapped hierarchically into a public NPM library and self-hosted API.
Chose a static JSON-first deployment architecture over SQL database lookups to enable direct CDN caching and offline integration.
ReviewScrap
Automated review intelligence system for 44 business branches. Centralizes Google Maps feedback into real-time analytics pipelines.
A hospitality chain with 44 physical locations had no way to monitor, aggregate, or instantly alert teams of negative Google Reviews.
Designed a centralized scraping pipeline that gathers Maps feedback and routes updates through direct Webhook alerts.
Used Bull + Redis queue workers to serialize and schedule requests across concurrent branches, bypassing Google's strict IP bans.
Dappermen
E-commerce platform optimized for Core Web Vitals, SEO, and Accessibility using Next.js and TypeScript.
An older storefront suffered from low Lighthouse scores (<60), resulting in poor search engine placement and lost conversions.
Rebuilt the ecommerce experience using Next.js static generation strategies, asset compression, and strict semantic HTML markup.
Leveraged Next.js Incremental Static Regeneration (ISR) to balance sub-second static page performance with real-time stock updates.
Movie Watch
Next.js streaming application with a full CI/CD pipeline, integrated GitHub Actions runners, and Cloudflare Tunnels.
Needed a private, cloud-independent media streaming suite that runs on home hardware without relying on expensive hosting platforms.
Configured a Next.js App deployed inside a local VM environment, utilizing secure, portless routing pipelines to the web.
Deployed on self-hosted Proxmox nodes routed via Cloudflare Tunnels, completely bypassing the requirement for static public IPs.
03 / Engineering Mindset
Engineering Philosophy.
Beyond code: How I structure systems.
Think in Systems
Before writing a single line, I map the full data flow. What goes in? What comes out? Where does it fail? This systems-first thinking prevents local optimizations that break global coherence.
When building the Vietnam address API, the challenge wasn't just parsing data — it was designing an endpoint contract that would remain stable as administrative boundaries changed every few years.
Model the Data First
The shape of your data is the shape of your product. Poorly modeled data creates technical debt that compounds faster than bad code. Clean schemas unlock clean code.
For every project, I invest time upfront in data modeling — entity relationships, normalization level, query patterns — before the first API route or UI component.
Ship with Intent
Shipped > perfect. But shipped also means: documented, versioned, and usable by someone who isn't you. Every project I ship has a README, a live deployment, and a clear use case.
The NPM package for vn-xaphuong-2025 was published with full TypeScript types, JSDoc comments, and a changelog from day one — because open source without documentation is just noise.
