About Frinko

Building towards the future

I’m Frinko — a Java Backend Engineer, AI Explorer, Investor and Lifelong Learner.

Frinko Lab is my digital garden: a place where production engineering meets AI experiments, market research, English learning and personal growth. I care about first principles, elegant systems, craftsmanship and the quiet compounding of good decisions.

What I explore

Engineering — Java, Spring Boot, databases, distributed systems and architecture
AI — Agents, RAG, LLM applications, evaluation and automation workflows
Investing — US equities, semiconductors and future technology
Learning — English, books, thinking systems and personal growth

Code. Think. Build. Invest. Evolve.

This is not a finished portfolio. It is a living record of becoming.
