Missed deadlines, buggy releases, and scalability bottlenecks aren't just technical issues. They are business risks.
Your site is slow and it's costing you money
Every extra second of load time drops conversions by 7%. I've rebuilt portals that went from 4s to under 1s and watched the numbers change overnight.

I've joined teams mid-crisis more times than I can count. At Cuez, I inherited a 3-second API and got it down to 300ms. I find bottlenecks fast and fix them.

Most AI pitches are vaporware. I build the practical kind: one client cut 40 hours/month of manual document processing. I automate support tickets, connect your tools, and eliminate the repetitive work your team shouldn't be doing.

I've been freelancing since 2009. I don't disappear. You get daily async updates, clear timelines, and a phone number you can actually call. My clients stay for years, not months.

My Guarantee
You talk to me, not a project manager
No account managers, no middlemen, no game of telephone. When you hire me, you work directly with the person writing the code.
If it ships, it works
I don't push code and pray. Everything gets tested, reviewed, and deployed with monitoring. If something breaks after launch, I fix it. No extra charge.
Deadlines mean deadlines
In 16 years I've never ghosted a client or missed a launch date. I deliver when I say I will, or I let you know early enough to plan around it.
