Hej! This is meAndika Septalonika
Building systems where precise interfaces meet resilient backends.
I build for scale and precision.
Full-stack developer with a Computer Science background, focused on building products that are technically excellent and genuinely useful.
I specialize in React, Next.js, Node.js, and PostgreSQL, with growing depth in cloud-native infrastructure and developer tooling.
Every project is a systems problem first and a code problem second.
Every project starts with a clear read of the problem space, constraints, and stakeholders before a line of code is written.
What is mine to own, what success looks like, and what the non-negotiables are — defined up front.
Decisions documented, trade-offs acknowledged, code reviewed and tested before it ships.
What improved, and why — tracked, not assumed, so the next project is sharper.

Tell me what you are building and where it is stuck. I read every message myself and reply within 24 hours.
Open to new product work and part-time collaboration. First reply comes with questions, a rough scope, and an honest answer on whether I am the right fit.
