Backend Engineer — Profile / 2026

Do Tuan Anh

Golang · Microservices · Distributed Systems · 5G Core

I build backend systems in Go — microservices, distributed systems, and 5G Core network functions — and run them on Kubernetes. I've shipped SSH-driven CLI platforms, HTTP proxies, and an eight-service polyglot prediction platform, with a research background in 5G network-slicing algorithms.

Experience

E-01

Software Developer

Viettel High Technology
  • Built a microservice-based CLI management system in Go and Java with a custom SSH server front-end, giving operators secure remote CLI access to monitor and control 5G network nodes.
  • Designed Role-Based Access Control across the CLI platform, and a high-performance HTTP reverse proxy in Go for internal service routing.
  • Deployed 5G core applications on Kubernetes and Docker; worked across PostgreSQL, MongoDB, and Aerospike.
  • Researched 3GPP 5G standards and defined API contracts for core network module groups with cross-functional teams.

Backend Developer Freelance

Company 19
  • Designed RESTful backend APIs in Go for business logic and high-concurrency request processing.
  • Built a multi-tenant architecture with per-tenant RBAC and camera access control, isolating data across customer organisations.
  • Developed a dynamic handler engine letting users compose event-driven workflows without code changes or redeployment.
  • Built a camera management subsystem: device registration, online/offline tracking, config updates, and live-stream control.

Selected work

P-01

go-stock-prediction

Polyglot microservice platform · personal

An eight-service distributed system that crawls Gold, NASDAQ, S&P 500, and crypto markets and serves ML price predictions through a web dashboard. Each service is written in the language that fits it — Go, Rust, Java, Python — talking over gRPC. Deployed publicly behind Cloudflare.

P-02

HTTP Reverse Proxy

High-performance proxy · Viettel High Tech

A high-performance reverse proxy in Go handling routing, middleware, and efficient request forwarding for internal 5G core services, with IP-based sticky sessions and end-to-end request tracing.

P-03

BnBStar

Network slice embedding · research

A search framework combining Branch & Bound with A* heuristics to solve the Network Slice Embedding problem in 5G virtual networks. Benchmarked against RL/DRL and classical baselines; results presented at a scientific conference.

P-04

Golang Navigator

VSCode extension · TypeScript

A VSCode extension for Go developers. It reads application logs and jumps to the exact source line a log statement came from — closing the gap between a log line and the code that produced it.
