About Me

I'm an Informatics undergraduate at Telkom University (2024-2028), originally from Kutai Kartanegara, building backend systems and exploring how software actually breaks.

My focus spans backend development in Go and Java, database design, network protocol analysis, and crypto/Web3, with cyber security as the direction I'm deepening next.

Current Focus

Area What I am exploring
Backend Development Designing and building backend services and APIs with Go and Java.
Databases Modeling, querying, and optimizing relational data for real applications.
Network Protocols Analyzing how network protocols work and where they can be broken.
Crypto & Web3 Exploring cryptographic primitives and decentralized systems.

Featured Work

Project Focus Why it matters

Research Direction

I care about systems that hold up under scrutiny: how services communicate, how protocols can be analyzed and attacked, and how backend architecture choices affect real-world security.
