Yakima, WA

IT for East of
the Mountains.

Software development, AI automation, and infrastructure
built for the Pacific Northwest — by someone who lives here.

GROUND TRUTH

Most regional IT
is reactive.

We build systems that don't break in harvest season.

We don't outsource your infrastructure to three time zones away.

We answer the phone. We show up.

Downtime costs more in October than April. Your systems should know that.

WHAT WE BUILD

Three disciplines.
One operator.

01 SOFTWARE

Software Development

Web platforms, mobile apps, AI agents, and custom automation — built in PHP/Laravel, Python, and React. Not generic, not over-engineered. Scoped precisely, shipped, and maintained by the same person you called to spec it.

02 INFRASTRUCTURE

IT System Administration

Linux systems, network security, cloud infrastructure (AWS, Cloudflare), and data integrity — managed by someone who answers when something breaks at 6 AM before a shift.

03 STACK

Tech Stack Management

We help you choose, connect, and actually use the right software — so your team stops fighting tools and starts using them. Integrations, migrations, and ongoing stack ownership.

ABOUT

One operator.
Full stack.

I'm Oleks Sobol — software engineer and systems operator based in Yakima, Washington. I build web platforms, mobile apps, AI-powered automation, and the infrastructure that keeps it all running — for agricultural operations, non-profits, and small businesses across the Pacific Northwest.

Entiat Systems is a solo practice. You talk directly to the person doing the work. No account managers, no handoffs, no three-week onboarding before anything happens.

YAKIMA VALLEY, WA

Harvest season
stresses everything.

Payroll spikes. Logistics multiply. Packing houses run 20-hour days. Cold storage systems can't go down. Connectivity failures cost more in October than they do in April.

We're from here. We build for the rhythm of this valley — not for a generic SMB somewhere with reliable fiber and an IT department.

JUN

right system.
