Projects

Some of the projects are from my own time.

Jinx — Digital-Goods Storefront & Payments Platform

A five-repo commerce platform for instant-delivery digital goods — a Next.js 16 storefront and operator dashboard on a NestJS API that runs its own crypto payment rails, reconciles peer-to-peer transfers nobody offers an API for, and treats every deliverable as a single inventory line that can only be sold once.

Aug 17, 20261

LightningProxies — Global Proxy Network Platform

The complete public platform for a 20M+ IP proxy network — product and pricing surface, a free network-diagnostics toolkit, market pages for 49 countries, and revenue-critical affiliate attribution hardened against bot fraud without ever blocking the page.

CleanProxies — Proxy & Bare Metal Network Site

A production marketing site for an ISP, residential, bare metal and VPS provider — five independently-modelled pricing configurators unified on one comparison route, a bespoke WebGL globe that costs nothing until it is on screen, and a design system delivered to pixel fidelity.

Easytools — Creator Commerce Platform

A full commerce platform for creators selling digital products — the complete public product surface plus the authenticated seller dashboard — delivered on Next.js 16 through a measurement-driven process that specified every section against exact computed values before a line of it was built.

PFO Proxies — Proxy Network Marketing Site

A Next.js 16 marketing site for a six-line proxy provider, built around an interactive canvas world-map of 1,033 mapped network nodes, a three-layer motion system that degrades safely to no-script and reduced-motion, and a synthesised audio layer that leaves every page server-rendered.

May 15, 20262

scrape.ly — Design System & Product Site

A web scraping platform's brand site built on a bespoke twelve-column editorial grid, a strictly layered design-token architecture with an enforced rule about what may reference what, and an A/B landing variant that reshapes the layout through CSS alone — no UI kit, no component-API cost.

Apr 29, 20261

RomConsult — Consultant Booking Marketplace

A full marketplace where clients browse digital marketing and cloud consultants, book them across timezones, and pay — a Next.js 16 front end on an accessibility-first component layer, backed by a NestJS API with background queues, TOTP two-factor auth, and a production self-hosted deployment.

Mar 26, 20261

proxylit — Proxy Infrastructure Site

A search-led product site for a six-line proxy network — a pricing calculator modelled per product line, per-country and per-integration coverage pages, a version-controlled content pipeline, and a documented design process where every significant change was specified before it was built.

Mar 25, 20262

Phantom Checker — Drop Monitoring Conversion Site

A conversion-focused site for a retail product-drop monitoring service, centred on a two-axis pricing configurator that resolves monthly event volume against seat count — with the entire scroll and header animation layer built directly on platform primitives rather than a motion library.

Feb 2, 20261

ACME Environmental — Abatement Contractor Site

A premium marketing site for a Massachusetts asbestos abatement and demolition contractor, built to convert a trust-driven purchase — a video hero, scroll-triggered credential and stat counters, and a project-type enquiry form, delivered on React 19 and Vite to pixel fidelity.

Nov 7, 20252

TryFinder — B2B Prospect Search & Contact Discovery Platform

A Next.js 16 prospecting platform — a marketing site and an authenticated search workspace sharing one hand-built design system, where Supabase sessions guard every route and contact data stays masked until a search credit is spent to reveal it.

Oct 21, 20251

CogPiece — Privacy-First DeFi Swap Platform

A Next.js 15 interface for a private cross-chain exchange — a WebGL-lit landing page whose hero is literally the live swap composer, a standard/private mode toggle built around a thirty-second batch auction, and a four-stage order tracker assembled from one set of shared cards.

Oct 16, 20250

KocerVPN — Bandwidth-Sharing VPN Marketing Site

A static multi-page marketing site for a free VPN funded by bandwidth sharing — built on Vite and Tailwind CSS 4, where the design work was converting a Figma export into a maintainable stylesheet and the copy work was making an unusual business model read as a fair trade rather than a catch.

Aug 18, 20251

Apptics — Subscription CRM Growth Surface

Two front ends for a Shopify subscription CRM — a long-form marketing site where the design team keeps working in Framer while engineering owns the bundle and the performance budget, and a ten-step qualification funnel that scores prospects, survives abandonment, and books them onto a sales call.

Aug 1, 20255

Minh Khôi — Car Rental Booking Platform

A production car rental platform for the Ho Chi Minh City market — a live fleet catalogue with availability, a three-step booking flow built for mobile conversion, and an operator dashboard for fleet, reservations, and pricing, running on the client's own domain.

Portfolio Tracker — Trading Dashboard & Charting

A trading portfolio dashboard built on the TradingView Charting Library — live position and P&L tracking, multi-timeframe professional charts, and watchlists, with the data layer tuned so a page full of streaming instruments stays responsive.

Dec 1, 20244

Let's Talk Wise — AI Interview Coaching Platform

An interview preparation platform pairing a web application with a Chrome extension — candidates run realistic AI-led mock interviews, get scored on content and delivery, and practise directly from the job listing they are applying to.

Page Daisy — Headless Shopify Storefront

A production-grade headless commerce storefront on Next.js with Shopify as the backend — server-rendered catalogue and product pages for search performance, optimistic cart updates for a checkout that feels instant, and internationalisation built in from the start.

A project and issue tracking application for small teams — typed issue lifecycle, assignment and filtering, and a dashboard view — built on Next.js with Prisma over serverless Postgres and rate-limited API routes.

Sep 21, 20241

beiryu.io.vn — Portfolio Platform

My own portfolio platform — an MDX-backed project archive with per-project view counting through Redis, statically generated pages with incremental revalidation, and a motion layer that stays accessible and never blocks first paint.

SketchPad AI — Sketch to Production Graphics

A design tool that turns rough whiteboard sketches into finished thumbnails and graphics through a diffusion-model pipeline — a browser canvas editor on a type-safe Hono and Postgres backend, with authentication, asset storage, and subscription billing wired end to end.

Apr 1, 20243

Life Evolution AI — Course Conversion Page

A conversion landing page selling an AI video course to a non-technical audience — the product demonstrated through before-and-after playback rather than described, with scroll-driven motion, a validated lead capture flow, and a page weight kept low enough for mobile ad traffic.

May 21, 20232

Engineering Blog — Notion-Backed Publishing

A personal engineering blog that uses Notion as its CMS — posts authored in a database and rendered as statically generated pages, with incremental revalidation, newsletter capture, and a custom domain.

Voice-Controlled Home Lighting — IoT System

A home automation system controlling mains lighting by voice through Google Assistant — an ESP8266 Wi-Fi bridge to an Arduino microcontroller driving a relay board, with a documented state machine covering the failure modes that matter when the load is mains power.

Mar 1, 20231

Game Hub — Video Game Discovery App

A game discovery application over a large public games API — search and multi-axis filtering by platform, genre, and rating, with a responsive grid, skeleton loading states, and client state kept lean enough that filtering feels instant.

Jan 1, 20231

Pathfinding Engine — Search Strategy Comparison

A pathfinding engine implementing four search strategies — DFS, BFS, Greedy Best-First, and A* — with custom heuristics, a reward-collection variant that turns the problem into constrained optimisation, and visual output comparing how each strategy behaves on the same map.

Nov 1, 20222

Seam Carving — CUDA Parallel Optimisation

A content-aware image resizing engine implemented in C/C++ and progressively optimised across three CUDA versions — profiling each stage of the algorithm, moving the parallelisable work to the GPU, and using shared memory to cut convolution cost.

Jun 21, 20221

Smart Contract Lottery — On-Chain Prize Draw

An Ethereum lottery contract in Solidity — entry priced in USD and converted at the live ETH rate, funds held in contract escrow, and a verifiably random winner selection, with the state machine and access control that keep a contract holding real value safe.

Jan 20, 20222

Screen Time Guardian — Distributed Process Control

A cross-platform parental screen-time system — an enforcement agent on the child's machine and a remote control app for parents — built around a genuine concurrency problem: two parents editing the same policy file from different devices without corrupting it.

Vietnamese Fake News Detection — NLP Classifier

A text classification system for Vietnamese news built end to end — language-specific preprocessing with proper word segmentation, feature extraction, multiple compared models, and a deployed web interface where an article can be pasted in and classified live.
