Portrait of Tiavina

I'm 22, from the east coast of Madagascar, and a software engineer driven by designing reliable systems, well thought out. What moves me is architecture, logic, and how solid a product stays once it meets the real world, like a well-tuned car ready to take the load.

(How I work)

Tiavina, software engineer

My work serves one purpose: saving time and money for the people who hire me, by actually solving their problem.

  • 01

    Analyse before coding

    I take the time to understand the need completely. It's the one phase where slowing down saves money.

  • 02

    Move, don't debate

    Once the need is clear, I build. No calls that stretch on, no topics left hanging in meetings: ship, test, fix.

  • 03

    Architecture that holds

    I build solid from the start, so the product takes the load without anyone having to start over.
