Hey, I’m

Jimmy

Fullstack Developer

I’ve been building software for over 10 years — web platforms, Web3 products, and mobile apps, from the interface you see to the systems behind it. I like simple experiences and thoughtful code.

Projects

Fullstack Developer

A meme coin launchpad on Robinhood where anyone can create a token in a few clicks, choosing between a tax token that routes a trading fee to the creator or a simple no-tax launch. Traders browse trending, hot, new, and graduated coins with live price, market cap, volume, holder, and liquidity data.

Fullstack Developer

A mobile app that helps people in IT speak up in English at work. Users rehearse real conversations out loud, such as standups, demos, code reviews, and incident calls, across 60 scenarios for eight fields, with live transcription, model answers, and optional AI feedback. 300 workplace vocabulary entries come with US and UK audio, Vietnamese meanings, and spaced review.

Fullstack Developer

A Mandarin vocabulary app for iPhone and Android built around spaced review, so every word comes back right before you would forget it. The same words are then practised through listening clips, reading passages, and handwriting, alongside decks, stats, a daily goal, and a home-screen widget. It is free, has no ads, and works offline.

Fullstack Developer

A multi-chain launchpad protocol that lets anyone create a token and run a token sale in a few clicks, with no code. Projects mint standard or deflationary tokens, launch branded presales, and lock liquidity after the sale, while buyers discover new launches across every supported chain.

Fullstack Developer

A meme coin launchpad for fair launches across EVM-compatible networks, Solana, and TON. Creators launch a token and open trading in minutes, while traders search fresh tokens by symbol, address, or chain and follow each bonding curve's market cap and progress live from the first trade.

Fullstack Developer

Non-custodial execution infrastructure that automates external trade signals on Hyperliquid. Traders connect a wallet, set position size, leverage caps, and loss limits up front, then enable execution for selected signal providers. PerpLab only trades within those delegated permissions, and funds never leave the user's wallet.

Fullstack Developer

A real-time DEX analytics and trading platform covering many chains and exchanges, from Uniswap and PancakeSwap to STON.fi. Users track trending pairs by price, transactions, volume, liquidity, and FDV, dig into token charts and liquidity data, and trade from a connected wallet.

Frontend Developer

A Japanese lifestyle and fortune content platform operated by LINE. It publishes daily horoscopes and zodiac rankings, articles on love, family, and wellbeing, personality tests, and manga columns, and connects readers to LINE's fortune-telling services.

Frontend Developer

A Japanese web novel platform from LINE where readers discover and read stories and writers publish their own work. It offers free writer registration, news on LINE Bunko releases, and companion mobile apps for reading on the go.

Fullstack Developer

A meme coin launchpad with real-time trading and analytics. Traders discover trending tokens with live volume and market cap, browse contested and listed coins, and filter or sort the market to catch new launches early.

Fullstack Developer

A Web3 whitelist launchpad that acts as a central hub for whitelist competitions. Projects create whitelist forms with tier-based entries and social media tasks on X, Discord, and Telegram to build hype before a fundraise, while participants enrol in projects and climb the leaderboard.

Frontend Developer

A Web3 token launchpad for investing in early-stage projects on BNB Smart Chain and Polygon. Projects apply to launch with the platform, and investors browse upcoming token sales and take part through the launchpad.

Frontend Developer

A Solana DEX for swapping thousands of tokens in real time with deep liquidity and competitive rates. Users connect a Solana wallet to swap tokens such as SOL and USDC and to provide liquidity to trading pools.

Fullstack Developer

A cross-chain bridge for the Finminity token (FMT) that moves holdings between BNB Smart Chain and Ethereum. Users connect a wallet, choose the direction, and transfer any amount up to their balance in a single step.

Frontend Developer

A mobile delivery app for sellers in Vietnam. Users create waybills with sender and recipient details, manage orders and pickup warehouses, calculate shipping fees, and find ShipFast drop-off points on a map.

Fullstack Developer

A Vietnamese price comparison platform that helps shoppers compare product prices across online stores before they buy.

Frontend Developer

A lottery ticket purchasing platform.

Frontend Developer

A social networking platform designed for high school students.

Fullstack Developer

A Vietnamese e-commerce store for power tools and electrical equipment, including brands like Makita. Shoppers search the catalogue, browse products by brand and category, and see prices and current promotions.

…and plenty more over the years — so many that I’ve honestly lost track of them all.
