Remote worker with 4+ years of experience - Last seen 4 months ago

👋 Hi, I’m Felix — a passionate backend engineer with 3+ years of hands-on experience building scalable systems and microservices. I specialize in Golang development and cloud-native solutions, with a strong focus on performance, data consistency, and security.

At PrivyID (Indonesia’s leading digital identity provider), I led major backend improvements to our user registration platform, scaling it to handle 3,000+ daily users across mobile and web platforms. I’ve worked extensively with technologies like:

Golang, gRPC, PostgreSQL, Redis

OAuth2, Two-Factor Authentication (2FA)

Firestore, Google Cloud Platform (GCP), GCS

Monitoring tools: Datadog, Graylog

I love solving complex backend problems — whether it's optimizing queries, building authentication pipelines, or integrating biometric verification.

🌍 Open to remote freelance or contract opportunities. Let’s build something amazing together!
