About Me
I am a full-stack Software Engineer specializing in scalable enterprise backends, cloud infrastructure, and AI integration. I graduated from Gadjah Mada University in Indonesia with a Bachelor's degree in Computer Science. My recent work in TelaAxon involves implementing serverless AWS environments, upgrading complex telecommunications systems, and integrating LLMs into cross-platform applications using Python, Ruby on Rails, NestJS, and Flutter.
I'd like to think of myself as a lifelong learner (stagnation is your first death!). Originally focusing on full-stack software engineering and computer vision in university, I have since expanded my curiosities to cloud infrastructure and computer networks as well. I love tackling architectural challenges, from end-to-end mTLS security, SIP and WebRTC routing, building automated CI/CD pipelines, resolving complicated Japanese sorting requirements, or optimizing high-volume SQL databases.
I've always been a bit of a nerd (complimentary). I graduated with cum laude in Computer Science (3.95 GPA) and achieved straight A+ grades during my international exchange program at Korea University. Combining this foundation with my background in data science, machine learning, and UI/UX design, I aim to bridge the gap between robust, secure backend architecture and intelligent, seamless user experiences.
If I'm not tinkering with code, I'm probably watching a Vtuber stream, playing video games, hopping around Kansai and doing karaoke with friends, or participating in language exchange events with strangers (currently working on JLPT N1!).

Experience
Software Engineer
TelaAxon
- Maintain a SIP PBX (Asterisk, Rails, Twilio) serving 100+ department stores; cut a 2M-record API query from 30s+ to 1s and reduced per-store deployment effort 60% with Ansible.
- Built mTLS certificate auth and a Keycloak session limiter for a major telecom's corporate phonebook app; led a zero-error production release.
- Built a NestJS + Flutter API for an AI beverage vending machine PoC, using Gemini to recommend drinks from flavor and fragrance inputs.
- Wrote ~90% of a serverless FastAPI health survey backend on AWS Lambda, with SQS + FCM batch notifications and Cognito JWT validation.
- Built GitHub Actions CI/CD for Lambda deploys and automated Alembic migration checks, cutting manual testing time by 50%.
