Backend builder / no-coffee human

Hi, I’m Vuong — I keep Java backends calm and helpful.

I have 4+ years building Java services, event pipelines, and small AI helpers so things stay smooth. I dabble in AWS when it matters and aim for quiet on-call nights.

What I’m about

I’m a backend engineer with 4+ years in Java, Spring Boot, Kafka, and the tooling that keeps them steady. I like tidy architecture, friendly automation, and performance that just stays fast. When AWS shows up, I keep to Glue, Lambda, and Step Functions.

Linux feels like home, so I self-host small experiments, script my chores, and poke at Unity when I need a brain reset.

Skills I lean on

Tools I grab to tame microservices, data streams, light AI, and cloud chores without extra fuss.

Java

Spring Boot services, JVM tuning, and calm retries when things wobble.

Spring

DDD lines, built-in observability, integrations that play nice.

Kafka

Event streams, steady consumers, and dashboards keeping lag in check.

AWS

Glue jobs, bite-size Lambdas, and Step Functions that keep chores tidy.

AI & automation

LLM prompts, safe guardrails, and bots that pitch in without drama.

Linux

Self-hosted labs, bashy automation, and logs that highlight the weirdness.

Projects

Quick peeks at builds that keep systems flexible, data honest, and dev life chill.

Dynamic Module Loader

Spring Boot with clean boundaries and runtime JAR loading. Add new domain pieces on the fly without waking ops.

Generic Report Service

JPA Criteria query builder with PDF/XLSX/CSV exports, caching, and delivery bots so reports go out on time.

Contact

Need a steady hand for your Java backend, a careful AI add-on, or a Linux buddy who documents along the way? Let’s team up.

Social

Prefer async updates? Email is best and I usually reply within a day.

How I help

My favourite projects make life lighter for engineers. I automate build and release loops, add observability early, plug in AI copilots only where they help, and keep docs beside the code so no one hunts a wiki maze.

Built with ♥, TailwindCSS, and a stubborn Linux box.
