About Me

Hi, I'm Davids Zalmanis.

I am an independent programming consultant with over 10 years of professional software development experience.

I specialize in stepping into complex technological environments, understanding business needs, and engineering solutions that are built to last. I don't believe in one-size-fits-all code; I believe in precise, tailored architecture.

How I work: I operate strictly on a contract basis. The vast majority of my engagements are done through billed hourly consulting. Before a single line of code is written, you and I will sit down, discuss the scope, and mutually agree on fair and transparent terms for the project. My goal is total alignment with your business objectives.
