Implementation of a microservice architecture using Go which demonstrates how to handle a user registration process, JWT authentication, and asynchronous email confirmation where a RESTful API service communicates with a background worker service via a message queue (RabbitMQ).
A Redis caching strategy which features user authentication with JWT, job posting, and job enrollment — with Redis handling both response caching and refresh token storage.
Building production-ready authentication system using Go, Gin, PostgreSQL, and Redis. It covers the full auth lifecycle — registration, login, token refresh, and logout — with security hardening applied at every layer.

Backend Engineer
I'm Yehezkiel Wiradhika (A.K.A Hezky): a Go (Golang) Backend Engineer focused on microservices and distributed systems. Currently shipping production backend systems at PT. Century Batteries Indonesia (Astra Otoparts), serving 600+ users across multiple internal platforms.
My primary stack is Go with Gin, GORM, gRPC (Protobuf), and Hexagonal / Clean Architecture. I build async event-driven systems with RabbitMQ, tune performance with Redis (caching, JWT token rotation, rate limiting), and deploy with Docker, Kubernetes, GitHub Actions, and Nginx. I monitor with Prometheus and Grafana and host on AWS. Day-to-day databases: PostgreSQL, MySQL, MongoDB. I've also built monolithic systems with PHP and Laravel and fullstack apps with Node.js, Next.js, and TypeScript when the job calls for it.
I write with a security-first mindset — backed by real offensive security experience: 20+ Web App and Network penetration tests at DPTSI ITS, hands-on with SIEM, IDS/IPS, Firewalls, and Honeypots. I occasionally build ML-powered security tools, including my thesis: "Statistical, Frequent Pattern Mining and Machine Learning based Web Honeypot Attack Data Analysis".
