Experience

Backend engineering roles across fintech, blockchain, and F&B tech.

Nov 2025 – PresentFintech

Zalopay (VNG Corporation)

Software Engineer

Design and maintain backend APIs for systems that integrate with a range of external services, focusing on clean interfaces and long-term maintainability.
Work on concurrency control and data consistency challenges across distributed systems, particularly in scenarios involving high request volume and shared state.
Apply fault-tolerant design patterns to gracefully handle disruptions in upstream services, so that temporary failures don't cascade into larger system issues.
Focus on performance and reliability tuning for containerized backend services, from resource allocation to runtime behavior under varying load conditions.

Dec 2024 – Nov 2025Blockchain

Phygital Labs

Software Engineer

Architected the Nomion platform backend (Go/Gin), bridging physical assets with blockchain via NFC to support 20K+ assets and 70K+ user interactions.
Cut incident resolution time by 40% by building an observability stack — Prometheus, Grafana, and Tempo — with real-time health dashboards.
Designed scalable API schemas for phygital storytelling and anti-counterfeiting authentication for luxury and retail brands.

AI-assisted Engineering

Leveraging LLM agents and MCP-based knowledge systems to streamline development, debugging, and incident investigation.

AI-assisted Development

Integrated Claude Code with customized agent skills to structure the development workflow end to end.

Requirement clarification & service identification
User-flow analysis & implementation planning
Unit test generation
Engineer-reviewed implementation

Engineering Knowledge Automation

Built an internal MCP-based knowledge system covering architecture, user flows, and codebase changes.

Automated weekly documentation updates
Tracks changes merged into master
On-demand engineering context for AI agents

AI-powered Incident Investigation

An automation agent for recurring support tickets that analyzes logs and user context before an engineer looks at them.

Analyzes service logs & user context
Identifies potential root causes
Attaches supporting evidence for verification

About

I'm Nhat Bich, a software engineer specializing in high-performance backend systems and distributed architectures. I've built scalable microservices in fintech and blockchain for platforms serving 17M+ users, with a focus on system observability and performance under real production load.

I'm finishing a Bachelor's in Software Engineering at the University of Information Technology (VNU-HCM), graduating in 2026. Outside of backend work, I spend time on AI-assisted engineering — using LLM agents and MCP-based knowledge systems to speed up development, debugging, and incident investigation.

Write-ups on backend engineering, security, and competitive programming.

October 12, 2022

[WRITE-UP] Information Security Competition – CTF – "WANNAGAME FRESHMAN 2022"

My write-up for the Programming category at WANNAGAME FRESHMAN 2022: Threesum Problem, The Shortest Path, and MITM.

Got an interesting problem, a side project, or just want to talk shop?

I enjoy conversations about backend systems, distributed architecture, and AI-assisted engineering. I read every message and usually reply within a day.
