Sound familiar?
Afraid to deploy
The app hasn't been updated in years. Every change risks breaking something. Deployments are manual and terrifying.
Can't hire for it
Nobody wants to work on old Java. The developers who know the system are leaving. New hires take 6 months to ramp up.
Consultancies want 12 months
Every firm that pitches you wants a year-long engagement with a 6-person team. You need results in one quarter.
Monday morning spreadsheets
Your team spends hours every week pulling numbers from 4 systems into a spreadsheet. The data is stale before anyone reads it.

15 years of enterprise delivery
"Partnering with Matt over several years at eVestment was a seamless experience. I never had to worry about any project he was involved in. His work was always executed quickly and thoroughly. He effectively managed an entire product line by himself, demonstrating exceptional reliability and expertise."
"During his time at Balto, Matthew consistently impressed me with his expertise in robust, efficient, and scalable solutions for our projects. His proficiency in crafting solutions and AWS made him an invaluable member of our team."
"What stands out is the quality of Matt's solutions. When others might take shortcuts, Matt engineers clean, maintainable solutions that stand the test of time. His code is something you can build on, not something you have to work around."
Hi, I'm Matt.
15 years building enterprise systems. I've worked with companies across financial services, pharma, ad tech, and music rights.
I started Katyella because legacy modernization projects don't need 6-person teams and year-long timelines. The right experience and AI-powered tooling can deliver what used to take a department.
Every engagement comes with documentation, team training, and a system your developers can actually maintain after I'm done.
