7+ years crafting high-impact backend solutions in finance, blockchain, AI & e-commerce. Architected 15+ microservices handling millions of transactions with 99.9% uptime.
I'm a Senior Software Engineer based in Vietnam, passionate about building reliable, scalable systems that make a real business impact.
My expertise spans across Go, Node.js, Kubernetes, and cloud-native architectures. I've built everything from high-throughput crypto deposit engines and non-custodial on-chain payout systems to AI-powered chatbots and MCP servers that let AI agents drive real software.
I care most about systems people can trust with money and data: secure by default, auditable end to end, and transparent enough that every payout and ledger entry traces back to its source.
I thrive in fast-paced environments where I can architect solutions from scratch, optimize existing systems, and mentor teams to deliver better software faster.

Transparent cashback service that returns up to 60% of exchange affiliate commission straight to traders' own wallets. Links Binance UIDs via referral, syncs commission reports every 6 hours, recalculates cashback every 30 minutes, and settles weekly USDT (BEP-20) payouts on-chain after admin reconciliation and approval. Fully non-custodial — no private keys held, no token locks — with a permanent, CSV-exportable audit ledger where every entry traces back to its source exchange report.
Stablecoin checkout where every order is settled by a Stellar payment that carries the order's own memo — the memo is the order, which makes each payment provable against it on-chain. Buyers connect any major Stellar wallet (Freighter, LOBSTR, Albedo and more), create an order and receive a payment slip, with balance checks that flag underfunded wallets before signing. Currently running on Stellar testnet.
MCP platform that lets AI agents — Claude Code, Codex CLI, Antigravity or any MCP client — drive creative software through one endpoint and one token, with access set per tool. Its first native server, Story Studio, exposes 50 tools over MCP to build, animate, narrate and export illustrated stories to video, including agent self-checks such as rendered preview frames and audio inspection. Wrappers for AutoCAD, SketchUp and Blender are on the roadmap.
Print-on-demand fulfillment service integrated with leading marketplace and store platforms — Shopify, Etsy and WooCommerce. Onboarded 100+ monthly active sellers and processed 200,000+ orders with 10.4% MoM sales growth (80K+ products imported, 20K+ user registrations), and architected automated, zero-delay fulfillment and shipment-tracking workflows with webhook + cron-driven order retrieval and zero-downtime deployments — driving the platform to $30K MRR with >90% merchant satisfaction.
“Made in Vietnam” AI interior design platform that turns a home into a personalised 3D design within 24–48 hours. Users digitise their space by uploading a 2D floor plan, capturing VR 360 photos that are stitched into a walkable VR tour, or LiDAR-scanning rooms on iPhone, then pick from 8 design styles learned from 500K+ architectural drawings. Customers shop decor directly inside the design, get rough cost estimates and connect with construction partners — from 30,000 VND/m², about a tenth of a traditional architect's fee.
Developed and maintained high-security custody services supporting multiple crypto exchanges and global trading platforms. Engineered real-time token transfer detection with customizable programmatic policies that trigger automated security workflows, and architected multi-chain support across diverse tokens using MPC (Multi-Party Computation) and HD (Hierarchical Deterministic) wallet architectures for optimal asset security.
PropTech platform for buying and renting apartments on Vietnam's secondary market. A real-time feed aggregates new sale and rental listings from the community and partners, and AI matches buyers to units by needs and financial capacity, with legal information vetted around the clock. Buyers walk through apartments in 360° VR tours, while Panorama AI analyses a room's current state and suggests interiors in the styles they like.
Backend systems powering Vietnam's leading English education provider — supporting student enrollment, course management and the OVI learning app used by students and parents.
Spearheaded end-to-end development of a Bitcoin-based meme-inscription platform — onboarding 1,000+ users at launch and minting 2,000+ inscriptions on the BTC blockchain in the first release cycle. Orchestrated deployment and maintenance of a production-grade Bitcoin full node and ordinals protocol server with automated monitoring and health checks, sustaining >99% availability for on-chain inscription and GameFi operations.

Author and maintainer. A harness that puts Claude Code, Codex and Antigravity CLI agents side by side as live terminal cards and lets them hand work to each other through a send_signal MCP tool — every run queued, capped and logged, behind guard rails such as an approval gate, ping-pong and daily caps and a kill switch. Ships built-in MCP servers (signal, boards, library, voice), a one-click MCP manager for every installed CLI, goal-to-task boards, media tools, and an OpenAI-compatible API, with prebuilt Windows releases plus macOS and Linux support.
Fork of Fystack's MIT-licensed Go indexer that detects deposits to watched addresses across 14 blockchains in real time. Rebuilt it as one static binary with one SQLite file, replacing NATS, Postgres, Redis, Consul/Badger and the bloom filter, and cutting the stripped binary from 34 MB to 22.6 MB. Matched transfers reach an HMAC-signed webhook through a SQLite outbox, in order and at least once, surviving restarts. Also contributed Solana parsing for Squads multisig transfers (transferCheckedWithFee) with unit tests upstream, merged in PR #84.
I'm currently open to new opportunities. Whether you have a question or just want to say hi, I'll get back to you as soon as possible!
