Three ways we help
Each one has its own page with examples and prices. Most clients start with a free written review.
Development partner for agencies
For web and marketing agencies with more projects than developers.
We take tickets or whole builds under your brand: React, Next.js, Laravel, WordPress. You keep the client relationship. We keep a fixed amount of time free for you each week, so nothing waits for a hire.
From $1,200 a month for 40 hours, or $35 an hour
Agency detailsLegacy app rescue
For companies running an old PHP or CodeIgniter app that nobody wants to touch.
We rebuild it on a current framework and run the old and new versions side by side until they behave the same. Then you switch over, with your data intact and a test suite for whoever works on it next.
Fixed price, quoted after a free review of your app
How a rebuild worksWebsites that bring in work
For trades, clinics and local services whose site is slow, out of date or broken on phones.
A fast new site that works on every phone, plus online booking and an automatic text back when you miss a call, so a job you can’t answer right away still comes back to you.

Hi, I’m Rafi.
I’ve shipped production software since 2019: six years as the sole engineer for an international foundation, whose apps serve 125+ people across 8 partner organizations, and now web work for a construction firm in New York. I studied engineering at Monash University and lived and worked in Sydney. Kodosys is how I work with clients directly.
I lead every project and review every change. AI agents write much of the code, which keeps prices fair and turnaround short. Automated tests decide what ships, and you can see them.
