I'm Adriano. I build software for founders who can't hire a CTO yet and for business owners tired of slow sites, broken tools, and freelancers who ghost. 17 years, 250 projects, fixed prices.

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 building software 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.

Four systems, one source of truth: HubSpot visibility for one of Brazil's largest vet networks
Built a custom integration layer for Reevia that connects four source systems into HubSpot for one of Brazil's largest veterinary companies. Over 2 million records processed with full normalization. Any lead from any system is inside HubSpot in under 50 seconds, standardized and ready to use.
For the first time, our teams all work from the same data. The integration runs silently in the background and just works.— Reevia
A custom CRM that turned Google Maps into a lead machine
Built a purpose-built CRM for a digital agency that captures leads from Google Maps, reaches them via official WhatsApp (Twilio + Meta API), and uses AI to suggest replies and standardize templates. The system scaled the lead base by over 500%, with 250 new leads entering the pipeline every day.
1,500 leads a day. We could never do that manually.— Norte Web Digital

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 17 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.
